Right now, if you stepped out onto the seawall in Corpus Christi, you’d feel a crisp, clear night. It’s exactly 42°F.
But that number is a bit of a lie. Honestly, it feels more like 36°F because of a steady 10 mph wind blowing in from the north. If you're planning your day for Sunday, January 18, 2026, things are looking up. You’ve got a high of 58°F coming your way under a perfectly sunny sky.
The low will bottom out at 40°F tonight. It’s classic January in the Coastal Bend—chilly enough for a heavy hoodie, but still clear enough to see every star over the bay.
Understanding what's the temperature in Corpus Christi Texas today
Texas weather is basically a mood ring. One day you’re in shorts, and the next, you’re looking for a scarf you haven't seen since 2022. For today, the humidity is sitting at a comfortable 43%, which is actually quite dry for this part of the world. Normally, we’re swimming in moisture.
Rain? Not a chance. The precipitation probability is a flat 0%.
If you’re heading out later this afternoon, the UV index is hitting a 4. It’s not summer-level intense, but the South Texas sun still bites even when the air is cool. Don't skip the sunscreen just because it’s 58 degrees.
Why the "Feels Like" matters here
People always ask about the "real" temp. In Corpus, the wind is the ultimate decider.
Because we’re right on the water, that 10 mph north wind makes the current 42°F feel significantly sharper. It's that damp, coastal cold that seems to get right into your bones. It’s different from a dry cold in the desert.
- Current Temp: 42°F
- RealFeel: 36°F
- Wind Speed: 10 mph (North)
- Today's High: 58°F
- Tonight's Low: 40°F
The seasonal shuffle in the Coastal Bend
January is officially the coldest month for the Sparking City by the Sea. Historically, the average high sits around 66°F, with lows hovering near 46°F. Today is actually running a bit cooler than the historical average.
By the time February rolls around, we usually see a jump. The averages climb into the 70s. Honestly, if you can make it through the random cold fronts of late January, you’re basically into the "false spring" that Texans love and hate.
If you’re visiting or just moved here, remember that the "cool season" is incredibly short—usually only about two and a half months. From early December to late February, we play this game of "Is it winter or is it just a long Tuesday?"
Summer is a different beast
Once May hits, the conversation about what's the temperature in Corpus Christi Texas changes entirely. We stop talking about jackets and start talking about survival.
August is the peak of the heat. You're looking at average highs of 93°F, but with the Gulf humidity, the heat index frequently cruises past 105°F. It’s the kind of heat where you can feel the air when you walk outside.
Practical steps for today
If you’re out and about in Corpus Christi today, dress in layers.
The transition from the morning low of 40°F to the afternoon high of 58°F is a 18-degree swing. It’s enough to make you regret a heavy coat by 2:00 PM but leave you shivering if you only brought a t-shirt.
- Morning/Evening: Stick to a wind-resistant jacket. That north wind at 10 mph is the main culprit for the chill.
- Mid-day: A light sweater or long-sleeve shirt will be perfect for the 58°F sunny peak.
- Hydration: Even though it’s cool and the humidity is low at 33-43%, the coastal air can be dehydrating. Keep some water on hand if you're hitting the trails at Oso Bay or walking the T-Head.
Stay warm out there. The sun is out, the sky is clear, and despite the 42°F start, it's shaping up to be a beautiful South Texas Sunday.
