The Lowdown
Alright folks, Rusty here. Let's be straight with you: the next couple of weeks are lookin' tough for getting wet around Galveston. This breakwater setup is gonna be starvin' for a while, so don't go gettin' your hopes up just yet. We're looking at a long stretch of weak, short-period leftovers with the wind all over the place. It's gonna be a waiting game.
We start off with a real flat spell. From Wednesday the 9th through to about the 21st, it's all thigh-high mush at best, and honestly, most of it won't even be that. Early on, winds are mostly cross-onshore and bumpy, and we've got a few days where thunderstorms are threatening to mess up the morning. The swell's tiny, with periods of just 3 to 6 seconds, and the energy readings are properly weak—down in the single digits and teens for the most part. There's a touch more energy around the 12th and 13th, but it's still only around 2ft and the period's short and fat. The water is 87°, which is a touch warmer than normal for this time of year, but you won't be feeling that on a board because you won't be on one. This is all just a whole lotta nothin'. We're talkin' a solid week with zero real surf on offer. The only thing to keep you occupied is watchin' the ripples.
Now, here's where things get interesting, but it's a double-edged sword. Around the 22nd and 23rd, a real swell finally shows its face, but it brings some serious wind with it. Tuesday the 22nd sees the swell bump up to 2-3ft, but with a strong cross-offshore breeze. Wednesday the 23rd is the one with the most size, hitting 4ft by the afternoon. The period's still short at 6-7 seconds, but the wave energy jumps up to 203, which is a moderate punch. However, this sets up with a gale-force offshore wind at 40 mph. I'm not kiddin'—it's gonna be howling. You'll get clean faces, but paddlin' out will be a death wish, and keepin' your hat on is a whole other battle. It's more of a "stand on the beach and watch the spray" kind of day.
But the real stand-out window, and what we've been waiting for, is on the 24th of September. A proper swell arrives. We're talkin' 5ft at 14 seconds—that's a long-period groundswell with some real grunt behind it. The combined energy reads a hefty 1004, which is strong to very strong. Here's the catch though: it's coming with a near gale cross-shore wind at 31 mph and some light rain, which is gonna wreck the surface. This is a big, powerful swell for the breakwater, and with that much energy and short period, it might be too much for the beginners. That size and power, combined with the wind, is going to make it a tough, gnarly paddle and strictly for the experienced crew. The swell direction is ESE/SE, which is good for the spot. It's promising, but it's a long way out, so treat it as a "watch the forecast" situation.
So, if you just have to get wet, the 24th is your best bet, but bring your big board, your bravery, and maybe a kite. For everyone else, keep your board in the car and keep an eye on those charts.
Rusty, out.

Information about the Galveston Surf forecast
The above surf forecast table for Galveston provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Galveston can be found by selecting the local surf guide option on the grey menu. Our Galveston surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Galveston) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Galveston may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Galveston is 3 km (2 miles) from Galveston. If you plan a vacation in Texas, look for hotels and other accommodation in Galveston. Galveston has rooms for a wide range of budgets as well as car hire and transport links.
