Baytown weather, month by month

Baytown's year is short winter, brief spring, long humid summer and a very good fall. Hurricane season overlaps the hottest months, so the monthly pattern is useful but never a substitute for the forecast.

The fuller answer

October and November are the best months, January the clearest, March the last comfortable one before summer, and June through September are hot, humid, stormy in the afternoons and inside hurricane season. The nearest long-record National Weather Service station, Houston Intercontinental Airport, has normal highs of 94.5 and 94.9 degrees in July and August and 63.8 in January, and about 52 inches of rain a year. It almost never snows. If you can pick a month, pick October.

What it's actually like, month by month, so you can plan the visit, the move, or the outdoor thing.

• January: the best month nobody expects. Highs in the sixties, lows in the forties, cold fronts every week or two that scrub the sky, the clearest views of the bridge all year. Rain some days. A jacket, not a coat. A hard freeze comes in some winters, and the town shuts for it.
• February: the same, warming. Crawfish season is under way, the first eighty-degree day surprises everyone, and mornings can be foggy near the river.
• March: spring, briefly. Seventies, wind off the bay, the migration at the Nature Center, the first mosquitoes. The patio month.
• April: eighties, humid, storms starting to build in the afternoons, the wildflowers along 146. Still good outside. The Battleground's reenactment is on the 21st.
• May: the door closes. High eighties, the humidity arrives to stay, the water park opens Memorial Day weekend, graduations. May is also one of the wetter months on the record, at about five inches.
• June: ninety-plus with a heat index over a hundred, afternoon storms most days, and the wettest month on the record at about six inches. Hurricane season opens on June 1, and the Crosby rodeo is this month. Everything outdoors before ten.
• July: the same, hotter. The water park, the library, the AC. Fireworks on the Fourth at Bicentennial Park. Beryl in 2024 was a July storm, which is the reminder that the season doesn't wait for August.
• August: the hardest month. Ninety-five, humid, storms, the peak of hurricane watching, the water park closing at the end of it (Pirates Bay's 2026 season ended August 30). School starts anyway.
• September: still summer for three weeks, then a first front around the twentieth that changes everything. Grito Fest lands at the end of September or the start of October, ninety degrees at six in the evening (the 2026 one was October 3). Hurricane peak; Ike was September 2008.
• October: the reward. Eighties by day, humidity falling after the fronts, three good Saturdays in a row, every patio perfect. In 2026 they are Grito Fest on October 3 at Bicentennial Park, which is behind us now, then the Nurture Nature Festival on October 10 at the Nature Center and the Market on October 17. It is still one of the wetter months on the record, at about five and a half inches, so carry a rain jacket. If you visit once, visit now.
• November: seventies, the fronts, Birding Week from November 18 to 22, the Turkey Trot, the lights going up. The second-best month, and the last of the Market on November 21.
• December: sixties, either sixty-five or forty on any given day, the parade the first Thursday, the plants sharp at night in the cold air. Rain some days. Snow almost never, and when it comes the whole town goes outside.

The numbers

These are the National Weather Service's 1991-2020 normals for Houston Intercontinental Airport, the nearest long-record station, about thirty miles west of Baytown. Baytown sits nearer the bay, so treat them as a guide to the season rather than the day.

The year averages 80.5 for the high, 60.5 for the low and 51.84 inches of rain at that station, with an all-time high of 109 degrees and a low of 5. The hurricane history, Alicia, Ike, Harvey and Beryl, is on the hurricane page with dates. Atlantic hurricane season runs from June 1 to November 30, and the peak is August through early October. If you can pick, pick October. If you can't, pick the morning after the first norther and be at Bayland with a jacket.

The rule

October and November for visiting; January for the sky; March for the patios; June through September for the indoors, with the water park open only until the end of August. The forecast on the homepage is live, from the weather service, every time you load it, with the sunset. The Baytown Nature Center at 6213 Bayway Drive is open every day except Christmas and Thanksgiving, with gates opening 30 minutes before sunrise and closing 30 minutes after sunset, so summer visits belong to the early hours. Bayland Park on Tabbs Bay is open 5 a.m. to 10 p.m. daily and is free. In the worst of July and August, the Eddie V. Gray Wetlands Center and the Sterling Municipal Library are the free indoor answers; both are closed on Sundays.

Before you go

Do outdoor things before ten from June through September, and carry water. Check the Nature Center's gate times, which follow sunrise and sunset. Pack a rain jacket for October even though the sky looks clear, because it is one of the wetter months. If you are booking a summer or early fall trip, buy trip insurance that covers named storms, since the season runs June 1 to November 30.

Questions people ask

• Does it snow in Baytown? Almost never; a dusting every few years.
• When is hurricane season? June 1 through November 30; the real window is August to early October.
• What's the best month to visit? October.
• How hot does it get? Normal highs at the nearest station are in the mid-nineties in July and August, with a heat index over a hundred most afternoons.

If you can pick, pick October. If you can't, pick the morning after the first norther, whenever it comes, and be at Bayland with a jacket. That morning is the town's best argument for itself. Pirates Bay Waterpark is the one reason to come in August, and it closes at the end of the month.

Radar, the forecast and warnings

The month-by-month numbers above are averages. For today's weather, the National Weather Service office that covers Baytown is Houston/Galveston, and its site carries the local forecast, hazards and radar. The City of Baytown's Warnings & Alerts page lists the rest: Baytown Alert for severe weather messages, the outdoor sirens that are tested every Wednesday at 9 a.m., AM 1610, which loops the NOAA forecast, and the Harris County Flood Warning System gauges on Cedar Bayou and Goose Creek. For the quick look, the live weather page shows conditions now, and the flood page explains the creeks.

El clima de Baytown, mes a mes

Baytown tiene un invierno corto, una primavera breve, un verano largo y húmedo y un otoño muy bueno. La temporada de huracanes (del 1 de junio al 30 de noviembre) se cruza con los meses más calurosos. Los datos del Servicio Meteorológico Nacional vienen de la estación del aeropuerto Houston Intercontinental, la más cercana con registro largo: máximas normales de 94.5 y 94.9 grados Fahrenheit en julio y agosto, 63.8 en enero y unas 52 pulgadas de lluvia al año. Casi nunca nieva.

Mes a mes

Enero y febrero son frescos y claros. Marzo y abril son una primavera breve, el mes de los patios. De mayo a septiembre hay calor de 90 grados, humedad y tormentas por la tarde; el parque acuático abre en Memorial Day y cierra a fines de agosto. Beryl llegó en julio de 2024 e Ike en septiembre de 2008. Octubre es la recompensa: temperaturas en los 80 y tres buenos sábados seguidos en 2026. El Grito Fest del 3 de octubre ya pasó; siguen el Nurture Nature Festival el 10 de octubre en el Nature Center y el Mercado el 17. Octubre sigue siendo un mes lluvioso, con unas 5.5 pulgadas, así que lleve impermeable. Noviembre trae la Semana de Aves (del 18 al 22) y las luces, con el último Mercado el 21; diciembre, el desfile el primer jueves.

La regla

Octubre y noviembre para visitar; enero para el cielo; marzo para los patios; de junio a septiembre, mejor bajo techo. El Baytown Nature Center (6213 Bayway Drive) abre todos los días salvo Navidad y Acción de Gracias, desde 30 minutos antes del amanecer hasta 30 minutos después del atardecer. Bayland Park abre de 5 a. m. a 10 p. m. y es gratis. En el peor calor, el Eddie V. Gray Wetlands Center y la biblioteca Sterling son la opción gratuita bajo techo; ambos cierran los domingos. Si va a viajar en verano u otoño, compre un seguro de viaje que cubra tormentas con nombre. Visite en octubre o noviembre.
