You’ve probably heard that Texas is just one giant, sweltering heat lamp. Honestly, if you’re looking at the weather in Corpus Christi Texas, that’s only about half the story. Sure, August will make you feel like you’re walking through a literal bowl of warm soup, but then January rolls around and suddenly you’re reaching for a hoodie because it’s 58°F and the wind is whipping off the bay at a clip.
It’s weird. One day you’re sunbathing at Padre Island National Seashore, and the next, a "Blue Norther" screams down the plains and drops the temperature 30 degrees in three hours.
The Reality of Weather in Corpus Christi Texas
If you are checking the forecast right this second—Sunday, January 18, 2026—it’s actually a gorgeous, crisp day. We’re looking at a high of 58°F with a low of 39°F tonight. It’s sunny, the humidity is unusually low at 21%, and there’s a light northwest breeze.
Basically, it’s "Chamber of Commerce" weather. But don't get too comfortable. By Tuesday and Wednesday, the humidity is going to skyrocket back into the 80% range, and we’ve got a decent chance of light rain. That’s the Coastal Bend for you. It’s a constant tug-of-war between dry continental air and that thick, salty moisture from the Gulf of Mexico.
Breaking Down the Seasons (The Non-Boring Way)
Most people think of the year in four parts. In Corpus, we kinda have three: "The Long Steam," "The Windy Nice Part," and "Wait, Is It Actually Cold?"

- The Long Steam (June - September): This is the heavy hitter. August is the hottest month, with average highs of 93°F or 94°F. But the high isn't the problem. It's the "feels like" temperature. When you factor in the humidity, the heat index regularly clears 105°F. September is the wettest month, averaging over 5 inches of rain, often coming in massive afternoon thunderstorms that dump water and then vanish.
- The Windy Nice Part (March - May & October - November): If you want to visit, this is the sweet spot. April and October are peak perfection. You get highs in the low 80s and enough of a breeze to keep the mosquitoes from carrying you away.
- The "Wait, Is It Cold?" Phase (December - February): January is the coldest month. The average low is around 48°F, but we’ve seen it dip into the 30s. It rarely snows—the average is literally zero inches—but the dampness makes the cold feel much sharper than a dry cold in West Texas.
The Wind: The City’s Unofficial Mascot
You can't talk about the weather in Corpus Christi Texas without mentioning the wind. It's almost always blowing. The city is consistently ranked as one of the windiest in the United States, usually averaging around 12 mph.
This is a godsend in July because it keeps the heat from becoming fatal. However, it’s a nightmare for kite flyers who aren't pros or anyone trying to keep a hat on their head. It also makes the city a world-class destination for windsurfing and sailing. If the wind stops blowing in Corpus, locals start looking around nervously like something is wrong with the simulation.
Hurricane Season and Survival
Look, we have to talk about it. Hurricane season runs from June 1 to November 30. While major hits like Harvey in 2017 are rare, tropical storms and "rain events" are just part of life here.
The peak is usually around September 10. If you're living here or visiting during that window, you basically just keep an eye on the National Hurricane Center and make sure your gas tank isn't empty. Most of the time, it's just extra rain and some choppy surf, but the city takes it seriously. There are evacuation routes mapped out—mostly heading north on U.S. 181 toward San Antonio or West on SH 44 toward Laredo.

Humidity: The Silent Mood Killer
The humidity here is subtropical. It stays high almost year-round, which is why your hair will never look the way you want it to.
Even in the winter, the humidity rarely stays below 50% for long. Right now, on this specific Sunday, we’re at a rare 21%, which feels incredibly dry for us. Usually, you can expect it to hover between 60% and 90%. It makes the summer "oppressive" (that’s the word the meteorologists love to use) and the winter "raw."
Actionable Tips for Navigating the Local Climate
If you are planning to spend time in the Sparkling City by the Sea, here is how you handle it like a local:
Pack for three climates. Even in the summer, the air conditioning in restaurants and the Texas State Aquarium is set to "Arctic Tundra." You will need a light jacket indoors. In the winter, you’ll need layers you can peel off as the sun comes out.

Hydrate or die. Not literally, but the combination of salt air and high heat will drain you faster than you think. If you’re fishing on the Bob Hall Pier or walking the seawall, drink twice as much water as you think you need.
Sunscreen is non-negotiable. The UV index today is a 0 because it's late afternoon, but during the day it hits 4 or 5 even in January. In the summer, it hits 10+ regularly. You will burn in 15 minutes without protection.
Watch the "Northers." If you see a dark line of clouds on the horizon and the wind suddenly shifts from the South to the North, get inside. The temperature will drop instantly.
The weather in Corpus Christi Texas is a living thing. It’s moody, it’s loud, and it’s rarely boring. Whether you're here for the beach or the bird watching, just respect the sun and the wind, and you’ll be fine.
Check the local buoy reports if you're heading out on the water, and always have a backup plan for a rainy afternoon at the USS Lexington. Honestly, the rain usually passes in an hour anyway. Just grab a taco and wait it out.
