Honestly, if you're looking at the 10 day forecast for rockport texas starting this Sunday, January 18, 2026, you’re looking at a classic Texas Gulf Coast rollercoaster. One minute you’re peeling off a hoodie because the sun is hitting just right, and the next, you’re hunting for a windbreaker because a "blue norther" decided to drop by for a visit.
Right now, Rockport is sitting at a crisp 39°F under a clear night sky. If you step outside, it feels more like 32°F thanks to an 11 mph wind coming straight out of the north. It’s cold. Really cold for a town known for palm trees and bay breezes.
The Immediate Outlook: Sun, Then the Shift
Sunday is going to be a gorgeous, albeit chilly, start. We’re looking at a high of 59°F with full-on sunshine. It’s perfect for the Rockport Fulton Market Days over on Seabreeze—just maybe bring a thermos of something hot. The humidity is super low at 31%, so it won’t feel "heavy," but that north wind is going to keep things brisk at 10 mph.
Monday, January 19, starts the climb. We’ll hit 66°F. The sun stays out for most of the day, but by nightfall, the clouds start rolling in. There’s a slight 20% chance of light rain overnight.
Mid-Week Reality Check: When the Rain Arrives
Tuesday through Thursday is where things get a bit messy. If you had plans to be out on the water, you might want to pivot.

- Tuesday, Jan 20: High of 67°F. Expect light rain throughout the day. Humidity jumps to 70%, so it’ll start feeling a bit muggy.
- Wednesday, Jan 21: This is the wettest day of the bunch. There’s a 65% chance of rain with a high of 67°F. The wind shifts to the south at a gentle 6 mph, but that humidity is going to pin you down at 88%.
- Thursday, Jan 22: The rain tapers off to a 20% chance. It’ll be partly sunny, but the wind picks up significantly, hitting 18 mph from the northeast.
Basically, if you’re a "Winter Texan" staying at one of the local RV parks, Wednesday is your day for a indoor hobby or hitting up the Bay Education Center for one of those public lectures.
The Weekend Curveball
By Friday, January 23, we’re back into the 70s. It’s going to feel like spring for about five minutes. Saturday, January 24, looks to be the warmest day of the forecast with a high of 73°F.
But don't get too comfortable.
Rain chances return Saturday night (20%) and linger into Sunday, January 25. By next Monday and Tuesday (Jan 26-27), the temperatures start sliding back down into the low 60s and high 50s. It’s that January cycle we all know—warm up, get rained on, cool down, repeat.
What This Means for Fishing
I talked to a few folks who keep a close eye on the Aransas Bay conditions. Captain Kenny Kramer and other local guides have been noting that with these lower winter tides, the "bite" has actually been pretty solid in the deeper guts and channels.
Since the water temperature has been hovering between 56°F and 65°F, the fish are active but they're huddling in the deeper spots where it's a bit more stable. If you’re heading out during a warmer window—like next Friday or Saturday—target the grass flats. For the colder, windier days like today or next Tuesday, stick to the 3-6 foot depths using live shrimp or cut mullet. Black drum and redfish don't mind the chill as much as we do.

Handling the Rockport Humidity and Wind
People always forget that 60°F in Rockport feels a lot different than 60°F in Austin or San Antonio. It's the salt air and the moisture.
When the humidity hits 88% like it will this Wednesday, that 67-degree air is going to feel damp and heavy. Conversely, when the wind kicks up to 22 mph (which we’re expecting by next Sunday, Jan 25), it’ll cut right through a light shirt.
Pro-Tips for the Next 10 Days
Check the UV index. Even on Sunday when it's only 59°F, the UV index is a 4. You can still get a "winter burn" if you’re out on a boat all day.
Dress in layers. Seriously. You’ll want a heavy coat for the 39°F mornings, but you’ll be down to a t-shirt by the time the 73°F Saturday afternoon rolls around.

If you're heading to the Texas Maritime Museum Mah Jongg Tournament on Friday, the weather will be great for travel, but the humidity might make the indoors feel a bit stuffy—plan accordingly.
Actionable Steps for Your Trip
- Pack for "Four Seasons": Bring a heavy fleece for the 39-46°F nights and a breathable rain shell for the mid-week showers.
- Watch the Tides: Winter tides in Rockport can get extremely low. if you're boating near the spoil islands or back lakes, be careful not to get grounded.
- Book Indoor Backups: Since Jan 21 looks like a washout, check out the Rockport Little Theatre or the local galleries in the Heritage District to stay dry.
- Monitor the North Wind: When it's blowing 15+ mph from the North/Northeast, stay on the protected sides of the bay to avoid the chop.
The 10 day forecast for rockport texas is manageable if you're prepared for the humidity spikes and the wind shifts. It's not exactly "beach weather" yet, but for birding at Aransas National Wildlife Refuge or hitting the markets, it's actually pretty decent coastal winter living.
