If you’ve ever spent a summer afternoon in Colorado County, you know the air in Sheridan doesn’t just sit there. It hugs you. Hard. Honestly, the weather in Sheridan Texas is exactly what you’d expect from a town tucked away in the coastal plains, but there are a few quirks that catch people off guard. It’s a place where the sky feels massive, the humidity is a constant companion, and the seasons don’t always follow the calendar you have hanging on your fridge.
Basically, Sheridan lives in a humid subtropical bubble.

The Reality of Sheridan Summers
Let’s not sugarcoat it: July and August are brutal. You’re looking at average highs that hover around 96°F or 97°F, but the "feels like" temperature is the real story here. Because Sheridan is only about 70 miles from the Gulf of Mexico, the moisture levels are sky-high. When that Gulf air meets the Texas sun, the dew points climb into the 70s, making it feel like you’re breathing through a warm, damp washcloth.
It's hot. Really hot.
Most locals plan their lives around the 10:00 AM cutoff. If you aren't done mowing the lawn or working outside by then, you’re probably waiting until sunset. Nighttime doesn't offer much of a "cool down" either, with lows often staying stuck at 73°F or higher. It’s the kind of heat that radiates off the pavement long after the sun goes down.
Rainfall Patterns and the "May Spike"
Sheridan gets about 42 inches of rain a year. That’s actually quite a bit more than the Texas average, but it doesn't fall in a nice, steady drizzle. Instead, you get these massive atmospheric dumps.
Historically, May is the wettest month, averaging around 5 inches. This is often when those classic Texas thunderstorms roll through, fueled by the collision of cool inland air and that warm, unstable Gulf moisture. If you’re visiting Splashway Waterpark in the late spring, keep an eye on the radar. Those storms move fast, and they pack a punch with frequent lightning and the occasional hailstone.
- Wettest Months: May and June.
- Driest Month: August (though it’s still humid as all get-out).
- Surprise Peak: September often sees a secondary spike in rain due to tropical activity.
Winter: The Season of "Maybe"
Winter in Sheridan is a bit of a gamble. One day you’re wearing a T-shirt in 65°F sunshine, and the next, a "Blue Norther" screams down from the plains and drops the temperature 30 degrees in three hours.
January is the coldest month, but "cold" is relative. The average high is 64°F and the low sits around 41°F. Snow? Forget about it. You might see a stray flake once every decade, but it’s mostly just "wet cold" which feels much chillier than a "dry cold" because of the lingering humidity.
The record low for the general region actually dipped below zero way back in 1899, but in modern times, you’re mostly just looking at a few nights of light frost. If you’re coming from the North, you'll think it’s spring. If you’re a local, you’re breaking out the heavy parkas the second it hits 50 degrees.

Why October is the Secret Favorite
If you’re asking for my honest opinion on the best time to experience the weather in Sheridan Texas, it’s October. Hands down.
By mid-October, the "humidity wall" finally breaks. The highs drop into the comfortable 78°F to 84°F range, and the air actually feels crisp. It’s the perfect window for camping or hitting the local lakes without the threat of heatstroke. Spring (March and April) is a close second, thanks to the wildflowers, but you run a higher risk of getting rained out by those May-style thunderstorms.
Severe Weather: What to Actually Worry About
Tornadoes get the headlines, but in Sheridan, the real threats are flash flooding and the occasional hurricane remnant. Since the town is relatively flat and sits at an elevation of about 266 feet, heavy tropical downpours can turn low-lying areas into ponds pretty quickly.

- Hurricane Season: From June through November, the town keeps a weather radio handy. Even if a storm hits the coast at Galveston or Matagorda, Sheridan can get hammered with 10+ inches of rain and tropical-storm-force winds.
- Thunderstorms: These are a year-round reality. The "lightning alley" effect is real here, and the storms in late spring can produce localized damaging winds.
Next Steps for Planning Your Visit:
- Check the Dew Point: Don't just look at the temperature. If the dew point is over 70, expect to sweat through your clothes in minutes.
- Pack for Layers: If you're visiting between November and March, the morning-to-afternoon temperature swing can be as much as 35 degrees.
- Monitor the Tropics: If you have a trip planned for August or September, check the National Hurricane Center (NHC) updates five days out.
- Hydrate Early: In Sheridan, if you wait until you're thirsty to drink water, the Texas heat has already won.
The weather in Sheridan Texas is a force, but if you respect the sun and time your visit for the shoulder seasons, it’s one of the most scenic parts of the Lone Star State to explore. Just don't forget the bug spray—mosquitoes love this humidity just as much as the local oak trees do.
