Las Vegas breaks most of the rules about when to fly. In most cities, weekends are cheap for hotels and summer is peak season; in Las Vegas, Friday and Saturday nights cost several times what a Tuesday does, and the hottest months of the year are among the cheapest. The city’s calendar is driven by three forces that have little to do with school holidays: the desert climate, which makes spring and fall glorious and midsummer punishing; the convention calendar, which can fill much of the city’s roughly 150,000 hotel rooms midweek with trade-show crowds; and a growing list of huge events, from the Electric Daisy Carnival to the Formula 1 Grand Prix, that can double room rates for a weekend. Airfares are the easier half of the equation, because Harry Reid International is one of the best-connected leisure airports in the country and competition keeps fares low. This guide walks through the weather month by month, the fare and hotel seasons, the events that move prices, and how to handle the airport.
The short answer
For the best weather, come in March to May or late September to early November, when days are warm, the pools are open and the desert parks are comfortable for hiking. For the lowest prices, look at July and August, when the heat keeps crowds away and resorts discount heavily, at the first half of December outside the rodeo, and at the weeks after CES in January. The most expensive stretches are New Year’s Eve, the Grand Prix weekend in November, big convention weeks such as CES in early January, and the spring and fall weekends generally, when the weather is perfect and the city is full. Whatever you choose, fly and stay Sunday to Thursday if you can, and check the convention calendar before you commit; then run a flexible-date search on our Las Vegas flights page, where shifting a trip by a couple of days can change the total cost dramatically.

Las Vegas weather, season by season
Las Vegas sits in a basin in the Mojave Desert, about 600 meters (2,000 feet) above sea level and ringed by mountains. It gets only about 100 mm (4 inches) of rain a year, sunshine on the great majority of days, low humidity, mild winters and some of the hottest summers of any large city in the country. The figures below are approximate seasonal patterns at the airport, based on the long-term climate normals published by NOAA and the National Weather Service’s Las Vegas office; check the current forecast before you pack, especially for heat warnings in summer and wind in spring.
| Month | Typical daytime high | Typical overnight low | What it feels like | Fare pressure |
|---|---|---|---|---|
| January | around 15 °C (59 °F) | around 4 °C (40 °F) | Cool, clear and sunny; cold after dark | High for New Year and CES, then low |
| February | around 17 °C (63 °F) | around 6 °C (43 °F) | Mild days, chilly nights, the odd rainy spell | Moderate; Super Bowl and Presidents’ Day weekends busy |
| March | around 22 °C (71 °F) | around 10 °C (50 °F) | Spring arrives; windy days are common | High; spring break and March Madness |
| April | around 26 °C (79 °F) | around 14 °C (57 °F) | Near-perfect; pools open, desert in flower | High |
| May | around 32 °C (89 °F) | around 19 °C (66 °F) | Hot afternoons, warm evenings, full pool season | High, with EDC and Memorial Day spikes |
| June | around 37 °C (99 °F) | around 24 °C (76 °F) | Very hot and dry; outdoor sightseeing at dawn only | Moderate, falling |
| July | around 40 °C (104 °F) | around 27 °C (81 °F) | The hottest month; monsoon storms possible | Low, except the Fourth of July |
| August | around 39 °C (102 °F) | around 27 °C (80 °F) | Extreme heat, more humid; flash-flood storms | Low |
| September | around 35 °C (95 °F) | around 23 °C (73 °F) | Still hot, cooling toward the end of the month | Moderate, rising |
| October | around 27 °C (81 °F) | around 15 °C (59 °F) | Warm, dry and bright; ideal for hiking | High |
| November | around 19 °C (67 °F) | around 8 °C (47 °F) | Pleasant days, cool nights | High for trade shows and the Grand Prix, low at Thanksgiving |
| December | around 14 °C (57 °F) | around 4 °C (39 °F) | Cool and sunny; frost some nights, snow on the mountains | Moderate for the rodeo, low mid-month, peak at New Year |
Three things the table cannot show. First, the heat is dry, until it isn’t: for most of the year the humidity is so low that 35 °C (95 °F) feels bearable in the shade, but the desert sun is fierce, you dehydrate faster than you notice, and from mid-June to mid-September walking between resorts in the afternoon is genuinely dangerous for some people. Second, the monsoon: from July to September, moisture from the south brings sudden afternoon thunderstorms, dust storms and flash floods that can close roads and turn dry washes into rivers in minutes. Third, the evenings: the desert cools quickly after sunset in winter and spring, so a warm January afternoon at the pool can become a jacket night by eight o’clock, while in July the overnight low barely drops below 27 °C (80 °F).
How Las Vegas fare seasons work
Airfares into Las Vegas are among the most competitive in the country. Harry Reid is a huge leisure market served by almost every U.S. airline, with Southwest the largest carrier and low-cost airlines such as Frontier and Allegiant adding capacity, so seats from the West Coast and the Mountain states are plentiful and fares rarely spike as sharply as hotel rates do. The real price swings in Las Vegas are in the rooms. Three calendars drive them: the weekly cycle, in which Friday and Saturday nights cost far more than Sunday to Thursday; the convention calendar, which can make a Tuesday the most expensive night of the month; and the weather, which fills the city in spring and fall and empties it in the heat. The result is that the cheapest total trip is usually a midweek stay in a low season with no big convention in town.
Peak season
March to May and late September to mid-November, plus New Year’s Eve and the biggest event weekends. Spring and fall weekends fill every resort on the Strip, and room rates on a Saturday can be several times the Wednesday rate. Stack a convention on top, and even midweek rates climb. If you must travel in peak, book early, stay Sunday to Thursday, and consider a downtown or off-Strip hotel, where rates rise less sharply.
Shoulder season
February, early June and early September. The weather is either not quite warm enough for the pool or a little too hot for comfort, and prices sit in the middle. February is interesting because the Super Bowl weekend is one of the busiest betting weekends of the year, and Chinese New Year and Presidents’ Day draw crowds; outside those, it is good value with mild weather.
Low season
Late June to August, the first three weeks of December outside the National Finals Rodeo, and the middle of January once CES has left town. Summer is the classic Vegas bargain: the resorts discount heavily to fill rooms, the pools are at their best, and everything but outdoor sightseeing works as normal. Early December is quiet and festive. Thanksgiving week, oddly, is also often cheap on the Strip, because business travel stops and the city is not a traditional family destination.
As elsewhere, mid-week departures and early or late flights usually price below Friday and Sunday afternoons on the same route, and a search across a whole month reveals cheaper pairs of dates close to your first choice. Our guide to the best times to book explains how to read those patterns, and our guide to cheap flight tickets to Las Vegas goes deeper on the airfare side.
Las Vegas month by month
January
The year starts expensive. New Year’s Eve, when the Strip closes to traffic for fireworks from the resort rooftops, is one of the priciest nights of the year, and CES, the giant consumer-electronics show in the first full week of the month, fills the city with well over 100,000 attendees and sends room rates soaring. Once CES leaves, January becomes one of the cheapest months of the year: cool, sunny days around 15 °C (59 °F), quiet casinos, and ideal hiking weather at Red Rock and the Valley of Fire. The Golden Knights are in season, and the NFL playoffs keep the sportsbooks lively.
February
Mild and good value, with a few spikes. Super Bowl weekend in early February is one of the busiest weekends of the year for the sportsbooks and the parties; Chinese New Year brings lavish decorations to the resorts and crowds from the West Coast and Asia; and Presidents’ Day weekend and Valentine’s Day, with the city’s famous wedding chapels at full stretch, fill hotels too. Midweek in February is excellent value.
March
Spring arrives, and so do the crowds. Spring break brings college students and families; college basketball’s conference tournaments early in the month and the opening rounds of March Madness fill the sportsbooks from morning to night; and the weather is warm enough for the pools to open. Windy days are common. Weekends are expensive; midweek is manageable.
April
Possibly the best month of the year: warm, sunny, not yet hot, with the desert in bloom and the pools and dayclubs open. It is also one of the busiest, with conventions midweek and full resorts every weekend. Book early, and consider the Easter weekend and the big April trade shows when choosing dates.
May
Hot afternoons and warm nights, full pool season, and two big spikes. The Electric Daisy Carnival, one of the largest dance-music festivals in the world, takes over the Las Vegas Motor Speedway for three nights in mid-May and fills hotels across the valley; Memorial Day weekend is the unofficial start of summer and one of the biggest pool-party weekends of the year. Between those, May is excellent.
June
The heat arrives in earnest, with highs near 37 °C (99 °F) and rising, and prices begin to fall through the month. Father’s Day weekend and the big summer trade shows add pressure, but late June is often good value. Do outdoor sightseeing at dawn and spend the afternoons in the pool or inside.
July
The hottest month, with afternoons around 40 °C (104 °F) and nights that barely cool. It is also one of the cheapest: outside the Fourth of July weekend, when the resorts put on fireworks and the pools overflow, room rates drop to some of their lowest of the year. The monsoon can bring thunderstorms and flash floods in the second half of the month. If you are coming for the casinos, shows, restaurants and pools, July is a genuine bargain.
August
Still extremely hot, a little more humid, and still cheap. The monsoon storms are at their most frequent, and the big cybersecurity conferences and fashion trade shows fill midweek rooms for a few days. The Aces are in season, and the pools stay open. Book the desert day trips for sunrise, or skip them until fall.
September
Summer hangs on, with highs in the 30s °C (90s °F) most of the month, but prices climb as the conventions return after Labor Day and the weather improves. The Raiders’ season starts, the college football season fills weekends, and the last week of September is often very pleasant. Labor Day weekend is the last big pool party of the year.
October
One of the two best months: warm, dry, bright and ideal for hiking Red Rock, the Valley of Fire and the Grand Canyon. It is correspondingly busy and expensive, with big conventions midweek and full weekends, plus Halloween, when the Strip’s clubs and bars throw costume parties all weekend. Book early.
November
A month of extremes. The SEMA auto-industry show in the first week brings one of the largest trade crowds of the year, and the Las Vegas Grand Prix, a Formula 1 night race on a circuit through the Strip, sends room rates for its weekend in the second half of the month to eye-watering levels and closes streets for days. Then Thanksgiving week is often one of the cheapest of the year. Days are pleasant and nights cool.
December
The National Finals Rodeo, ten days in the first half of the month, brings cowboy hats, country concerts and full hotels to the whole city. The rest of early and mid December is quiet, festive and inexpensive, with the resorts dressed for the holidays and the Ethel M cactus garden lit up. From Christmas to New Year’s Eve, prices climb steeply for the biggest party of the year.

Events that move Las Vegas flight and hotel prices
Cross-check these against your dates before you book. Exact dates shift each year; the Las Vegas Convention and Visitors Authority keeps the current calendar, including the major conventions.
- New Year’s Eve: the most expensive night of the year on the Strip.
- CES (the first full week of January): the biggest convention of the year.
- Super Bowl weekend (early February) and Chinese New Year (late January or February).
- March Madness (conference tournaments and the opening rounds, early to mid-March) and spring break.
- Electric Daisy Carnival (three nights in mid-May) and Memorial Day weekend.
- Fourth of July and Labor Day weekends: the big pool-party weekends.
- SEMA (early November) and the Las Vegas Grand Prix (a weekend in the second half of November).
- National Finals Rodeo (ten days in the first half of December).
- Big fights, residency openings, Raiders and Golden Knights games and stadium concerts. Our Las Vegas events page shows what is on sale for your dates.
- Midweek trade shows, which can fill the city without warning; if your Tuesday rate looks higher than your Saturday rate, that is usually why.
Getting in from the airport
Harry Reid International Airport (LAS), named after the former Nevada senator and known as McCarran until 2021, is one of the busiest airports in the country and sits directly beside the south end of the Strip, about 8 km (5 miles) from its center. It has two terminals: Terminal 1, which handles Southwest and many domestic airlines, and Terminal 3, which handles international flights and several domestic carriers, connected airside by a tram to the D gates. Yes, there are slot machines at the gates. Getting to the Strip is quick: taxis wait at both terminals and the ride takes 15 to 25 minutes; ride-hail pickups are in designated areas of the parking garages; shared shuttle vans serve the major resorts; and RTC buses stop at the terminals, though with luggage and a transfer they are slower. All the rental companies operate from the off-airport Rent-A-Car Center, about 5 km (3 miles) away and reached by free dedicated shuttle buses from both terminals. Our Las Vegas rental car guide works through whether you need one, and our LAS airport guide covers the layout.

Timing tricks that work for Las Vegas
- Check the convention calendar first. A cheap fare into a CES or SEMA week is not cheap once the room is added. Run a Las Vegas hotel search for the same dates before you commit to either.
- Stay Sunday to Thursday. Weekend nights on the Strip can cost several times the midweek rate for the same room; even shifting one night makes a difference.
- Compare total prices. Nightly resort fees and parking charges add a substantial amount to the advertised room rate, so compare the all-in price, not the headline.
- Use the summer. If the pool, the shows and the restaurants are the point, July and August offer the lowest rates of the year; do the desert at dawn or save it for another trip.
- Consider driving from Southern California or Arizona. Las Vegas is a classic road trip from Los Angeles and Phoenix; see our Los Angeles to Las Vegas and Las Vegas to Phoenix route guides.
- Leave time at the airport. Security lines at LAS can be long on Sunday and Monday mornings after a big weekend or convention. Our guide to how early to arrive covers what to allow.

What to pack, by season
Winter (December to February): layers for mild days, a warm jacket for evenings that drop close to freezing, and sunglasses. Spring (March to May): light clothing, swimwear, a layer for the evenings, and sunscreen, because the sun is already strong. Summer (June to September): the lightest clothing you own, a hat, high-factor sunscreen, a refillable water bottle, and a sweater for the aggressively air-conditioned casinos and theaters. Fall (October to November): summer clothing into October, with a jacket for the cooler nights of November. In every season, bring comfortable walking shoes, because a stroll between two neighboring resorts can be longer than it looks, and something smarter for the restaurants and nightclubs, which enforce dress codes.
The best time to fly to Las Vegas for…
Pool parties
April to early June, and September, when the dayclubs are in full swing and the heat is manageable; Memorial Day and Labor Day weekends are the biggest parties.
Hiking and the national parks
March to May and October to November for Red Rock, the Valley of Fire, Zion and the Grand Canyon; winter works for the lower desert parks but brings snow to the Grand Canyon’s South Rim and Zion’s higher trails.
Shows and dining on a budget
July and August, the first half of December, or mid-January to early February, midweek.
The lowest fares and rates
Midweek in July, August or early December, with no major convention in town.
Families
Spring break or a fall break for comfortable weather for the Hoover Dam and the parks; summer is cheap, but the heat makes outdoor sightseeing hard with children.
International visitors
Canadians need a valid passport; visitors from Visa Waiver Program countries need an approved ESTA before boarding, and everyone else needs a visa. U.S. Customs and Border Protection explains what applies to you, and the TSA lists what you can carry through security. Grand Canyon National Park and the other national parks charge an entrance fee per vehicle; the National Park Service sells passes online and at the gates.
Frequently asked questions
What is the cheapest month to fly to Las Vegas?
July and August are usually the cheapest for the whole trip, followed by the first half of December and mid-January after CES. Airfares vary less than hotel rates, so the room is where the savings are.
What is the best month to visit Las Vegas for weather?
April and October, with March, May and early November close behind.
Is Las Vegas too hot in summer?
For outdoor sightseeing in the afternoon, yes; highs around 40 °C (104 °F) are normal. For the pools, casinos, shows and restaurants, which are all air-conditioned or built for the heat, summer is fine and far cheaper.
Why are Las Vegas hotels so expensive on some weekdays?
Conventions. The city hosts some of the largest trade shows in the world, and a big one can fill every resort midweek. Check the convention calendar before booking.
Is it cheaper to go to Las Vegas midweek?
Almost always. Sunday to Thursday nights are far cheaper than Friday and Saturday, unless a large convention is in town.
How far ahead should I book?
Earlier for New Year’s Eve, the Grand Prix, EDC, CES week and spring and fall weekends, when rates only rise; for midweek summer and early-December stays, rates are stable enough that finding the right dates matters more.
Does it rain in Las Vegas?
Rarely, about 100 mm (4 inches) a year, but winter storms and summer monsoon thunderstorms can bring sudden downpours and flash floods. Never drive into a flooded road.
