So, you're looking at the 5 day forecast galveston and trying to figure out if you should pack a swimsuit or a parka. Honestly, that’s the eternal Galveston struggle. One minute you’re walking down the Seawall in flip-flops, and the next, a "blue norther" screams across the bay and makes you regret every life choice that didn't involve a heavy wool sweater.
This week is a classic example of that coastal moodiness. We’re starting with crisp, bright Texas winter days and heading straight into a soggy, humid mess by mid-week. If you're planning to visit the Strand or hit up Restaurant Week, you're gonna want to keep a close eye on Wednesday.
The Current Vibe: Sunny but Chilly
Right now, as of Sunday afternoon, January 18, it’s actually gorgeous out, if a bit brisk. We’re sitting at 51°F with a light northwest wind. It’s the kind of day where the sun feels warm on your face, but the air has a real bite to it.
The rest of today stays pretty much like this. We're looking at a high of 52°F and a low of 41°F tonight. If you're heading to the Galveston Symphony Orchestra at The Grand 1894 Opera House this evening, definitely bring a coat. The walk from the parking lot to the theater can be wind-whipped.

Monday: The Last "Dry" Day
Tomorrow, Monday, January 19, is looking like the sweet spot. It’ll be sunny with a high of 58°F.
- Morning: Clear skies, great for a walk on the beach.
- Afternoon: High of 58°F, humidity starts creeping up to around 59%.
- Night: Clouds move in, and we drop to 49°F.
It’s MLK Day, so expect the island to be a bit busier than a typical Monday. If you’re participating in the MLK Unity Parade, the weather should cooperate perfectly—just standard "layer up" weather.
The Big Shift: When the Rain Hits
Tuesday is when things get kinda weird. The wind flips to the east and kicks up to about 18 mph. When that happens in Galveston, it starts dragging in all that moisture from the Gulf. The humidity jumps to 67%, and the high hits 63°F.

It’ll be cloudy all day. You might feel a few stray drops, but the real party (and by party, I mean the "I can't see the end of the pier" kind of rain) starts Wednesday.
Wednesday’s Washout
If you have outdoor plans for Wednesday, January 21, maybe... don't? We’re looking at a 75% chance of heavy rain during the day.
The humidity is going to be a staggering 88%. Basically, you'll be breathing soup.
The wind stays southeast at 14 mph, which usually means the tide might stay a little higher than usual. Speaking of tides, if you're a fisherman or just like to walk the jetties, the low tide at the North Jetty is predicted for 10:50 AM, with a high around 6:39 PM. But with heavy rain and southeast winds, those predicted heights can be a bit unpredictable.

What to do when the 5 day forecast galveston goes south
Look, nobody likes a rainy beach day, but Galveston is actually built for this. Since we’re right in the middle of Galveston Restaurant Week (which runs through the 30th), Wednesday is a perfect excuse to just go on a food crawl.
- Shearn’s Seafood: They’re actually doing a wine pairing dinner with Cline Family Cellars on Wednesday night. If it’s pouring outside, being tucked away with a glass of wine and a view of the moody Gulf is a top-tier move.
- The Museums: Galveston Museum Weekend is coming up soon, but places like the Bryan Museum or the Moody Mansion are solid escapes from the humidity.
- The Grand: Check out the Starry Night Market on Thursday if the rain lets up. It’s scheduled for 6 PM to 10 PM. Even if it’s cloudy, the art and live music vibe at Anne Lane Gallery is worth the trip.
Thursday: The Aftermath
By Thursday, January 22, the "heavy" part of the rain should be over, but don't expect the sun to come out and say hi. It’s going to stay cloudy with a high of 58°F. The humidity actually peaks here at 92%. It’s going to be that damp, "everything feels slightly sticky" kind of cold.
Expert Tips for Navigating Galveston Weather
Most people see "sunny" and think "beach day." In January? That’s a gamble. The water temperature right now is hovering in the mid-50s. Unless you’re wearing a thick 4/3mm wetsuit, you aren't swimming.
- Watch the Flags: Even if the sun is out, check the flags at the lifeguard stands. A yellow flag is standard, but if you see purple, it means marine life (like man-o-war) has blown in.
- The "Seawall Chill": The temperature on the Seawall is always about 3-5 degrees cooler than it is "in-town" or over the bridge in Texas City because of the onshore breeze.
- Fog Factor: With the humidity spiking Wednesday and Thursday, watch out for sea fog. It can get so thick on the 45 bridge that you can barely see the car in front of you.
Basically, this week is a tale of two islands. Sunday through Tuesday morning is for the outdoors—birding at the Coastal Heritage Preserve or geocaching. Wednesday and Thursday are for the indoor gems.
Next Steps for Your Trip:
- Check the Tide: If you're planning to hit the West End pockets, verify the tide charts via Tides Today or Surfline, especially with the southeast winds on Wednesday.
- Book Your Table: Since it's Restaurant Week, the popular spots like Gaido's or Hearsay on the Strand fill up fast when it rains.
- Pack Smart: Bring a waterproof shell for Wednesday. A regular cotton hoodie will just soak up the humidity and stay damp for three days.
