If you’ve ever stood on the banks of Lake Livingston in the middle of July, you know exactly what "thick" air feels like. It’s that heavy, swampy humidity that makes you feel like you’re wearing the atmosphere rather than just standing in it. Weather in Point Blank Texas is a unique beast, even by East Texas standards. It's a tiny town with a population of barely 1,000 people, but its position right on the water changes the local climate in ways that can catch you off guard if you aren't prepared.
Honestly, the weather here is basically dictated by two things: the Gulf of Mexico and the massive lake sitting right in the backyard.
You’ve got the heat, sure. Everyone knows Texas is hot. But Point Blank isn't the dry, dusty heat of El Paso or the flat, windy heat of Lubbock. It’s a moist, forested heat that smells like pine needles and lake water.
Why the Lake Changes Everything
Most people looking at the forecast for San Jacinto County think they’re getting a standard read. They aren't. Being perched on the western shore of Lake Livingston creates a microclimate.
During the summer, the lake acts like a giant heat battery. While the sun goes down and the piney woods start to cool off, the water stays warm. This keeps the nighttime lows in Point Blank a few degrees higher than they might be just ten miles inland. On the flip side, in the early spring, that same body of water can keep the immediate shoreline a bit cooler when the rest of the state is starting to bake.
It’s a trade-off.

You get the breeze off the water, which is a lifesaver in August, but you also get the "lake effect" humidity. According to historical data from the National Centers for Environmental Information (NCEI), humidity levels in this part of Texas frequently hover around 70% to 80%. When the thermometer hits $95^\circ\text{F}$, that dew point—which often settles in the mid-70s—makes the "feels like" temperature skyrocket past $105^\circ\text{F}$.
The Real Numbers: Highs, Lows, and Everything Between
If you’re planning a trip or moving here, you need the hard data. No fluff.
- Hottest Month: August takes the crown. Average highs hit $94^\circ\text{F}$, but record days have seen it climb well over $100^\circ\text{F}$.
- Coldest Month: January is the "brr" month. Expect highs around $61^\circ\text{F}$ and lows near $40^\circ\text{F}$.
- Annual Rainfall: Point Blank is wet. We're talking 52 inches of rain a year on average.
Compare that to the national average of 38 inches. It rains a lot here. October is surprisingly one of the wettest months, often seeing over 5 inches of precipitation as the seasons try to shift.
Winter in Point Blank is weirdly short. One day you're wearing a heavy coat because a "Blue Norther" wind just blew in from the plains, and 48 hours later, you’re back in a t-shirt because the wind shifted south. Hard freezes happen, but they’re rarely long-lived. Snow? Forget about it. You might see a stray flake once every three years, but it’s usually gone before you can get your phone out to take a picture.
Severe Weather and the "H" Word
Living this close to the coast (about 80 miles inland from the Gulf) means you have to talk about hurricanes.

Point Blank isn't on the beach, so it doesn't get the catastrophic storm surge that wipes out places like Galveston. However, it gets the rain. And the wind. When a system like Hurricane Beryl or Harvey moves through, Point Blank becomes a target for inland flooding.
The soil here is a mix of clay and sand. When 10 inches of rain falls in a single afternoon—which isn't unheard of during a tropical depression—the ground just stops absorbing it. FEMA data suggests that while Point Blank isn't in a primary 100-year flood zone, the 500-year flood risk is actually quite high (around 68%).
Expert Note: If you are staying near the lake, pay attention to the dam releases at Lake Livingston. The Trinity River Authority manages the water levels, and heavy rains upstream in Dallas eventually flow down to us, affecting local water levels even if it didn't rain a drop in Point Blank that day.
Spring and Fall: The "Golden Windows"
If you hate the heat and fear the floods, there are two times a year when Point Blank is actually perfect.
Late March to April is spectacular. The dogwoods bloom in the woods, the bluebonnets pop up along Highway 190, and the temperature stays in that sweet $70^\circ\text{F}$ to $80^\circ\text{F}$ range. It’s the best time for hiking the nearby Sam Houston National Forest.

The second window is late October through November. The humidity finally breaks. The air gets crisp. You can actually sit outside without being eaten alive by mosquitoes (which thrive in the humid Point Blank summers).
Survival Tips for the Texas Humidity
If you're going to survive a summer here, you have to change how you live. Local life slows down between 2:00 PM and 6:00 PM. That’s not laziness; it’s survival.
- Hydrate with more than just water. When you sweat this much, you lose electrolytes.
- Check the dew point. Ignore the "temperature." If the dew point is over $70^\circ\text{F}$, it doesn't matter if it's "only" 85 degrees—you're going to be miserable.
- Watch the sky. Afternoon thunderstorms in the summer are sudden and violent. They’ll drop the temperature 15 degrees in ten minutes, but they also bring dangerous lightning.
Honestly, the weather in Point Blank Texas is a bit of a roller coaster. You’ll have weeks of stagnant, hazy heat followed by a tropical deluge that turns your backyard into a pond. But when those fall breezes kick in and the sun sets over the lake, you kind of forget about the $100^\circ\text{F}$ days.
Next Steps for Your Trip or Move:
- Check the National Weather Service (NWS) Houston/Galveston office for the most accurate radar, as national apps often miss the small lake-effect cells.
- If you’re boating, install a "Windy" or "FishWeather" app to track gust speeds on Lake Livingston, which can get choppy incredibly fast during a cold front.
- Keep a basic "go-bag" during June-November (Hurricane Season) just in case a slow-moving system causes local road closures due to downed pines or flash flooding.
