You’re waking up in 77055, maybe near Spring Branch or just off the Katy Freeway, and you look out the window. It’s early morning, January 17, 2026. If you’re like most people in this corner of Houston, you probably checked your phone and saw it’s about 51°F right now. But honestly, it feels more like 48°F because of that bite in the air.
Houston weather is a fickle beast. One day you’re wearing shorts to a backyard BBQ, and twelve hours later, you’re digging through the attic for a puffer jacket you swore you wouldn't need.
Right now, we are sitting under a partly cloudy sky. The humidity is surprisingly low for our swampy standards—down at 27%. That’s why it feels "crisp" instead of just "wet cold." There’s a north wind blowing at 8 mph, which is basically the universe’s way of reminding us that winter actually exists in Southeast Texas, even if it only shows up in three-day bursts.
The Real Deal on Weather Houston TX 77055
If you’re planning your weekend, don't get too comfortable. Today, Saturday, we’re looking at a high of 56°F. It’ll be mostly sunny, so the Vitamin D will be there, but that 10 mph north wind is going to keep things chilly. Tonight is the real kicker. We’re dropping down to 37°F.
Basically, if you have sensitive plants out on the patio near Gessner or Bingle, you might want to bring them in. It's not a hard freeze, but it’s close enough to make a hibiscus drop its leaves in protest.
People think Houston is just "hot and hotter," but the 77055 zip code actually sees some of the weirdest micro-swings in the city. Because we have so much concrete around the I-10 corridor, we get a bit of that urban heat island effect during the day, but the open spaces in the older residential parts of Spring Branch allow the heat to escape quickly at night.
What the Next Few Days Look Like
- Sunday, January 18: It’s going to be a gorgeous, clear day. High of 57°F, low of 36°F. Perfect for a morning run if you don't mind the cold air hitting your lungs.
- Monday, January 19: We start warming up. High of 64°F. The wind shifts to the southeast (the "humidity direction"), and the clouds start rolling back in.
- Tuesday, January 20: Getting gray. It’ll be cloudy all day with a high of 61°F.
- Wednesday, January 21: This is your "stay inside" day. We’ve got a 75% chance of rain. High of 63°F, but it’s going to be that messy, light-to-moderate rain that makes 290 and I-10 a total nightmare.
Why 77055 Flooding Isn't Just About Rain
When people search for weather Houston TX 77055, they aren't just looking for the temperature. They’re looking for "is my street going to turn into a river?"

The 77055 area is interesting. We’re in the Buffalo-San Jacinto watershed. While we aren't directly on the coast, we have significant "pluvial" risk—that’s just a fancy word for surface flooding when the drains can’t keep up with a sudden downpour. Experts at ClimateCheck note that while our annual rainfall might actually stay around 45 inches, the intensity of individual storms is rising.
Basically, we get the same amount of water, but it all likes to fall in two hours instead of two days.
If you live in Spring Branch North, you’re generally in a "Low Flood Risk" zone (FEMA Zone X), meaning you aren't in the 100-year floodplain. But as anyone who lived through 2017 remembers, those maps don't always tell the whole story.
Surviving the Seasonal Whiplash
January is technically our coldest month. The average high is 64°F and the low is 47°F. But averages are liars. In reality, you’ll see 73°F one day (like we did yesterday) and then wake up to 37°F today.

First, check your tire pressure. This sudden drop from 70s to 30s will trigger that annoying "low PSI" light on your dashboard. It’s not a leak; it’s just physics. Second, if you're heading out to Memorial City Mall or hitting any of the spots along Long Point, dress in layers. You'll want the coat for the parking lot, but you’ll be sweating once you get inside.
Lastly, keep an eye on Wednesday’s rain. With an 88% humidity jump and a heavy rain forecast, the morning commute is going to be a mess.
Check your windshield wipers today while it’s dry. If they’re streaking or squeaking, swap them out now. You don't want to be the person hovering at 35 mph on the Katy Freeway because you can't see through the gray mist. Stay warm tonight, 77055—it’s going to be a cold one.
