Best Time to Fly to Houston: Seasons, Weather & Prices

Houston is a business city first, and its airfares show it. Two big airports, a United Airlines hub at Bush Intercontinental and a large Southwest Airlines operation at Hobby, compete for the traffic of the energy industry, the Texas Medical Center and one of the busiest convention calendars in the country, which keeps weekday flights full all year. Leisure demand layers on top: the rodeo in late February and March, spring break, the holidays, and the cruise passengers heading for Galveston. The weather adds its own twist. Houston’s winters are mild and its springs and falls are lovely, but its summers are long, hot and humid, and the city sits in the path of Gulf of Mexico hurricanes from June to November, which is exactly why late summer brings some of the lowest hotel rates of the year. This guide walks through the weather month by month, the fare seasons, the events that move prices, and how to choose between IAH and Hobby.

The short answer

For weather, the best windows are mid-October to early December and March to April, when days are warm, the humidity eases and the city lives outdoors. For value, late August and September and January after the holidays are usually the cheapest times to fly and to book a room, though late summer is hot and falls in the most active part of hurricane season. The most expensive stretches are rodeo season and spring break, from late February to mid-March, the week of the Offshore Technology Conference in early May, when the energy industry fills every hotel in the city, Thanksgiving, and the Christmas and New Year weeks. Whatever you choose, run a flexible-date search that includes both airports on our Houston flights page; a shift of a few days around the rodeo or a big convention can change the fare band entirely.

Houston’s weather, season by season

Houston sits on the flat coastal plain about 80 kilometers (50 miles) from the Gulf of Mexico, and the Gulf defines its climate: warm, moist air for most of the year, heavy rain that can fall in any month, long humid summers, and short winters broken by cold fronts from the north. The figures below are approximate seasonal patterns based on the long-term climate normals for Bush Intercontinental from NOAA’s National Weather Service Houston/Galveston office; check the current forecast before you pack, because a Gulf downpour or a winter front can change the day in an hour.

Three things the table cannot show. First, the humidity: from May to September the air is heavy with Gulf moisture, mornings are muggy even before sunrise, and the heat index, which combines temperature and humidity, is what you will actually feel. The National Weather Service issues heat advisories most summers; take them seriously, drink water and plan outdoor sightseeing for early morning or evening. Second, the rain: Houston receives around 50 inches (about 1,270 mm) a year, spread across every month, and it often arrives in short, intense downpours that can flood underpasses and low streets within an hour. Never drive into water on the road. Third, the hurricane season, which the next section covers in more detail.

Hurricane season, in perspective

The Atlantic hurricane season officially runs from June 1 to November 30, and the greatest risk to the Texas coast is from mid-August to early October. Most years pass without a direct hit on Houston, and most summer trips go ahead without a second thought, but the city has been struck hard in the past: Hurricane Harvey brought catastrophic flooding in 2017, and Hurricane Beryl knocked out power across much of the region in July 2024. The practical advice is simple. If you are booking for August through October, choose fares and hotels with flexible change policies or consider travel insurance that covers named storms, watch the outlooks from NOAA’s National Hurricane Center in the week before you travel, and remember that storms are tracked for days before they arrive, so airlines usually issue travel waivers well in advance.

How Houston’s fare seasons work

Three calendars drive seats into Houston. The first is business: the energy industry, the Medical Center, NASA contractors and the port keep Monday-morning and Thursday-evening flights full in every season, and big conventions at the George R. Brown Convention Center and NRG Park can fill downtown hotels without warning. The second is leisure, concentrated in rodeo season, spring break, the holidays and the cruise season out of Galveston. The third is the weather, which pushes visitors away in late summer and pulls them back in the fall. Because Houston is served by two large airports with different main airlines, competition on popular routes is strong, and a fare that looks high at one airport is often lower at the other.

Peak season

Late February to mid-March, for the Houston Livestock Show and Rodeo and spring break; the week of the Offshore Technology Conference in early May; Thanksgiving week; and the Christmas and New Year fortnight, from roughly the third week of December to the first days of January. During the rodeo, hotels near NRG Park and downtown fill for the big concert nights, and Texas school spring break, usually in the middle two weeks of March, adds families flying in and out. OTC week is the single sharpest hotel spike for business travelers. In summer, flights stay reasonably busy because Houstonians are flying out on vacation, but hotels in the city are soft.

Shoulder season

April to May outside OTC week, and October to early December outside Thanksgiving. These are the months with the most comfortable weather and moderate prices; October and November in particular are the local favorites. Watch Easter, Memorial Day, the Astros’ October playoff runs, and big home football weekends.

Low season

January after New Year’s week and early February, and late August through September. January is mild and quiet, apart from Houston Marathon weekend in mid-January. Late summer is hot, humid and in the heart of hurricane season, and it is when downtown and Galleria hotels discount most heavily; if you can handle the heat and book flexibly, it is excellent value.

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.

Houston month by month

January

Mild and changeable, with highs in the 60s °F and the occasional cold front that makes a jacket necessary for a day or two. After New Year’s week it is one of the cheapest months to fly and to stay, and it is a comfortable time for Space Center Houston, the museums and the bayou. The Houston Marathon in mid-January fills downtown hotels for one weekend. Hard freezes are rare but do happen; when they do, the city is not built for ice and roads can close for a day.

February

Mild, with azaleas starting to bloom by the end of the month. Fares stay low through the first half, then climb when the Houston Livestock Show and Rodeo opens in late February with its barbecue contest and trail rides. Mardi Gras is celebrated on Galveston Island in the weeks before Lent, and it fills the island’s hotels on its weekends.

March

Warm, green and beautiful, with azaleas in River Oaks and bluebonnets along the highways outside the city. It is also the busiest leisure month of the year: the rodeo runs into mid-March with a concert every night, and Texas school spring break, usually in the middle of the month, adds family travel. Book early, and compare IAH and Hobby.

April

One of the best months to visit, warm and pleasant before the humidity builds, with patio season in full swing and the Art Car Parade bringing hundreds of decorated vehicles to the streets. Spring storms can be severe, with hail and heavy rain, so keep an eye on the forecast. Fares are moderate apart from Easter weekend.

May

Hot and increasingly humid, with the chance of heavy rain. The Offshore Technology Conference at NRG Park in early May draws tens of thousands of energy-industry visitors, and hotel rates across the city jump that week; check the dates before you book. Memorial Day weekend is busy on the roads to Galveston. Otherwise, fares are moderate.

June

Summer arrives in earnest, and hurricane season begins on June 1. Afternoon thunderstorms are frequent. Juneteenth on June 19 is celebrated in Emancipation Park and in Galveston, where the holiday began, and Houston’s Pride celebrations take place during the month. Flights are busy with summer travelers, but city hotels start to soften.

July

The hottest, most humid month, with the heat index often above 100 °F (38 °C). The Fourth of July brings fireworks downtown, and the rest of the month is for air-conditioned museums, roofed baseball at Daikin Park, and early-morning or evening outings. Hotels are at their cheapest of the year, and fares ease after the holiday.

August

Just as hot, with rising tropical storm risk. Houston Restaurant Weeks, when many of the city’s restaurants offer fixed-price menus for charity, run through the month and into early September. Families head back to school in mid-August, and fares and hotel rates fall. Book flexibly.

September

Still hot and humid, and the peak of hurricane season. It is usually the cheapest month of the year for flights and hotels, and most years it passes without incident, but watch the forecasts in the days before you travel and avoid non-refundable bookings where you can. Labor Day weekend is busy on the roads to the coast.

October

Relief. The first real cold fronts arrive, the humidity drops, and the city moves back outdoors. It is often the best month of the year to visit. Fares are moderate, though large conventions and an Astros playoff run can tighten hotels on particular weeks, and the Texas Renaissance Festival draws weekend crowds northwest of the city through the fall.

November

Mild, dry and sunny, with comfortable days for Galveston, the bayou and outdoor dining. Fares are moderate until Thanksgiving, when the week’s flights are among the most expensive of the year; the city’s Thanksgiving parade runs downtown that morning. The week after Thanksgiving is a good-value window.

December

Mild, with occasional gray days and short cold snaps. The first half of the month is quiet and reasonably priced, with holiday lights across the city and ice skating at Discovery Green. From around the third week of the month, fares jump for the Christmas and New Year weeks as Houstonians fly home and visitors arrive.

Events that move Houston flight and hotel prices

Cross-check these against your dates before you book. Exact dates shift each year; Visit Houston keeps the current calendar.

• Houston Marathon (a Sunday in mid-January): fills downtown hotels for one weekend.
• Houston Livestock Show and Rodeo (about three weeks from late February into March): the city’s biggest leisure event; the rodeo’s site has dates and the concert lineup.
• Texas spring break (usually mid-March, varies by school district).
• Offshore Technology Conference (early May): the sharpest business-hotel spike of the year.
• Juneteenth (June 19) and Houston Pride (June).
• Fourth of July, Memorial Day and Labor Day weekends, when Galveston and the coast fill up.
• Hurricane season (June to November, peaking from mid-August to early October): low prices, higher risk.
• Thanksgiving and Christmas to New Year.
• Astros playoff runs, Texans home games, and stadium concerts. Our Houston events page shows what is on sale for your dates.
• Big conventions, which can fill downtown hotels on weeknights; if your mid-week rates look strangely high, that is usually why.

Getting in from the airport

Houston has two commercial airports, both run by the Houston Airport System. George Bush Intercontinental (IAH), about 37 kilometers (23 miles) north of downtown, is the larger: a major United Airlines hub with nonstop flights across the United States and to dozens of cities in Latin America, Europe, Asia and the Middle East, and several terminals linked by an airside train. The drive downtown takes 30 to 45 minutes without traffic and closer to an hour at rush hour; taxis and ride-hail pick up outside every terminal, a shuttle bus runs to the consolidated rental car center, and METRO’s local bus service to downtown is cheap but slow. William P. Hobby (HOU), about 11 kilometers (7 miles) southeast of downtown, is dominated by Southwest Airlines, has a compact terminal with an international concourse for flights to Mexico, Central America and the Caribbean, and is 20 to 30 minutes from downtown by car. Hobby is also the closer airport for Space Center Houston and Galveston. Our guides to IAH and Hobby cover the layouts, and our Houston car-versus-transit guide works through whether to rent.

Timing tricks that work for Houston

• Search both airports. United dominates IAH and Southwest dominates Hobby, and the cheaper airport changes from route to route and week to week. A calendar search on TicketScanner that includes both shows the difference instantly.
• Book the hotel first for the rodeo and OTC. A cheap fare is not cheap once the room is added. Run a Houston hotel search for the same dates before you commit to either.
• Fly mid-week, stay the weekend. Business traffic makes Monday morning and Thursday evening the priciest flights on most routes, while downtown and Galleria hotels often discount Friday and Saturday nights.
• Book flexibly in late summer. August and September are the cheapest months, and a refundable fare or a flexible hotel rate costs little extra insurance against a tropical storm.
• Pair Houston with Dallas. The two cities are about four hours apart on I-45, and fares into Dallas sometimes undercut Houston; a one-way rental makes a classic Texas trip. Our guide to the best time to fly to Dallas covers that end.
• Allow time at IAH. Security and immigration lines can be long at peak times; our guide to how early to arrive covers what to allow.
• Flying out of Houston instead? The same seasonality applies in reverse; see cheap flights from Houston.

What to pack, by season

Summer (June to September): the lightest, most breathable clothes you own, a hat, sunscreen, a refillable water bottle, a compact umbrella for the afternoon storms, and a light layer for the fierce air-conditioning indoors. Spring and fall (March to May, October to November): light clothes for warm days, a light jacket for the evenings and the odd cold front, and rain gear. Winter (December to February): layers and a medium jacket; most days are mild, but a front can drop the temperature sharply overnight. In every season, comfortable shoes for the museums and something smarter for Houston’s restaurants, which dress up more than visitors expect.

The best time to fly to Houston for…

The rodeo

Late February to mid-March, booked as early as you can manage, with the hotel first and concert tickets bought when the lineup is announced.

Space Center Houston and Galveston

April to May or October to November, when the weather is warm enough for the beach but not punishing, and the Space Center’s tram lines are shorter than in the summer holidays.

The best weather

Mid-October to early December and March to April. Days are warm, evenings are comfortable, and the humidity is manageable.

The lowest fares

Late August and September, and January after the holidays. For late summer, book flexibly and keep an eye on the tropical forecast.

Families

Spring break is busy but ideal for the Space Center and the museums; the week after Thanksgiving and late October are calmer. In summer, lean on the indoor attractions and plan Galveston for the morning.

International visitors

Visitors from Visa Waiver Program countries need an approved ESTA before boarding; most others need a visa. The State Department’s travel site explains what applies to you, and the TSA lists what you can carry through security. IAH handles most long-haul arrivals, so allow time for immigration and customs.

Frequently asked questions

What is the cheapest month to fly to Houston?

September is usually the lowest, followed by late August and January after New Year’s week. Early December before the holiday rush is also good value.

What is the best month to visit Houston for weather?

October and November, with March and April close behind. Summer is hot and humid; winter is mild but can be gray.

Should I avoid Houston during hurricane season?

Not necessarily. The season runs from June to November and most visits are unaffected, but from mid-August to early October book flexibly, consider travel insurance, and check the National Hurricane Center’s outlook before you go.

How hot does Houston get in summer?

Highs are typically in the mid-90s °F (about 35 °C) in July and August, and the humidity pushes the heat index above 100 °F (38 °C) on many days.

Should I fly into IAH or Hobby?

Compare both. IAH has far more international flights and is the United hub; Hobby is closer to downtown, the Space Center and Galveston, and is Southwest’s base.

How far ahead should I book?

Earlier for the rodeo, spring break, OTC week, Thanksgiving and Christmas, when fares tend only to rise; for late summer and January, finding the right dates matters more than booking early.

Does it snow in Houston?

Very rarely. Measurable snow falls only once every few years at most, but hard freezes do happen occasionally in winter, and the city is not equipped for ice when they do.
