You've probably been there. You're staring at your phone, checking the cypress tx weather hourly forecast, trying to figure out if you can actually squeeze in a round at BlackHorse or if you’re about to get drenched. It’s a classic Southeast Texas gamble. Living in Cypress isn't like living in a place with predictable "seasons." We have a vibe. And that vibe is basically "anything goes," especially during these weird transition months.
Honestly, the biggest mistake people make is trusting a 24-hour forecast like it’s gospel. In Cypress, the weather doesn't care about your plans. Because we’re tucked just far enough northwest of Houston to miss some of the coastal tempering but close enough to the Gulf to catch all the humidity, things get weird. Fast.
Why the Hourly Forecast Feels Like a Liar
It’s Tuesday, January 13, 2026. If you look at the cypress tx weather hourly today, you’ll see a high of 56°F and a low of 45°F. Sounds straightforward, right? Light showers are hanging around with about a 51% chance during the day. But here is the thing: a "50% chance of rain" in Cypress doesn’t mean it will rain half the time. It usually means it’s going to pour on your neighbor’s house in Bridgeland while you’re bone-dry over in Coles Crossing.
We are currently in a La Niña cycle for the 2025-2026 winter season. National Weather Service experts like Barry Goldsmith have been tracking this for months. Basically, La Niña usually means we’re warmer and drier than average. But "drier" is a relative term when you live in a swamp. Even in a dry year, the Cypress Creek watershed is always lurking.
Short sentences matter here: The rain is erratic. The humidity is heavy. The wind, currently kicking at about 7 mph from the west, feels sharper than it should because the air is so damp.
The 3:00 PM Slump
Have you noticed how the temperature always seems to peak and then plummet the second the sun ducks behind a cloud? In January, we lose daylight fast—sunset is around 5:44 PM today. Between 2:00 PM and 4:00 PM, you might feel great in a t-shirt. By 6:00 PM, you’re looking for that Patagonia puff jacket you swore you wouldn't need this year.
The Cypress Creek Factor
You can't talk about cypress tx weather hourly without talking about the water. We live in a 320-square-mile drainage collection basin. That is the largest in Harris County. When the hourly forecast shows a "moderate" rain event, locals know to check the Harris County Flood Warning System (FWS).
Why? Because our topography is flatter than a pancake. The elevation drops maybe one inch every 100 feet. When we get those intense bursts of rain—the kind where the hourly forecast jumps from 10% to 80% in an hour—the water has nowhere to go.
I remember talking to a guy who moved here from the Midwest. He thought "flash flood" meant a river overflowing. I told him, "No, man. In Cypress, a flash flood means the street in front of your driveway is now a lake because the storm drains are overwhelmed."

- Pro Tip: If you see the hourly precipitation climb above 0.5 inches in a single hour, stay off the feeders.
- The Wind: Watch for gusts. Today they’re mild, but in the spring, those 15 mph averages can spike to 30 mph in a heartbeat.
- The "Feels Like" Gap: A 56°F day with 49% humidity feels totally different than a 56°F day with 90% humidity. Today is actually relatively crisp and dry for us.
Misconceptions About Winter in Cypress
Most people think Texas winters are a myth. They aren't. They’re just short and bipolar. January is statistically our coldest month, with average lows hitting about 44°F.
But look at the 2026 outlook. We are seeing "punctuated" extremes. This is a term climate experts use to describe long stretches of mild, 70-degree weather broken up by two or three days of absolute "Arctic Express" freezing. You'll be wearing shorts on Monday and wrapping your pipes on Wednesday.
The cypress tx weather hourly data for late January often hides these "blue northers." These are cold fronts that move so fast the temperature can drop 30 degrees in two hours. If you aren't checking the hourly breakdown, you'll leave the house in a light sweater and be shivering by lunch.
Humidity: The Invisible Weight
Even on a "cool" day, the humidity in Cypress rarely stays low. We average about 79% relative humidity in January. It’s that damp, "get in your bones" cold. It’s not the dry, crisp cold you get in Denver. It’s a wet chill that makes 50°F feel like 35°F.
Practical Steps for Timing Your Day
Stop looking at the daily high and start looking at the "Dew Point" and "Wind Chill" on your hourly app. If the dew point is within 5 degrees of the temperature, expect fog. Cypress gets thick, "pea soup" fog in the mornings near the Barker Reservoir and the various man-made lakes in Towne Lake.
If you're commuting down 290 or the Grand Parkway, that 7:00 AM hourly slot is the most dangerous.
How to actually use the data:
- Check the 3-hour window: Don't look past three hours. In Southeast Texas, the models struggle with accuracy beyond that.
- Monitor the "Wet Bulb" during freezes: If we get a freak ice alert (rare but possible in late Jan 2026), the wet bulb temperature tells you if the rain will actually stick to the roads.
- Wind Direction: A north wind means dry air is coming. A south wind means the Gulf is "breathing" on us, bringing back the stickiness.
Ultimately, navigating the weather here is about being skeptical. The apps are tools, not prophets.
If you're planning an outdoor event this weekend, keep a "Plan B" for indoors. Even with the La Niña "drier" forecast, the 26% daily chance of rain is a permanent fixture of life here. Basically, keep an umbrella in the trunk and a jacket in the backseat, regardless of what the screen says.

What to Do Next
If you are serious about staying dry and safe, stop relying on generic weather apps. Bookmark the Harris County Regional Flood Warning System website. It gives you real-time data from gauges actually located in Cypress, not at Bush Intercontinental Airport (IAH). The airport is 30 miles away; the weather there isn't your weather.
Also, take five minutes to check your gutters today. With the light showers predicted for this afternoon, you want to make sure that water is moving away from your foundation. Cypress soil is mostly clay, and it expands and contracts like crazy. Keeping your perimeter dry during these hourly rain cycles is the best thing you can do for your home’s long-term health.
