The Lowdown
Alright, Rusty here. Gotta give it to you straight: the next two weeks at Galveston are pretty much a bust for any real surfing. It’s a long stretch of ankle-high windswill with mostly crummy wind directions. The whole 16-day window has no standout days, and honestly, no surf worth chasing.
It kicks off Wednesday the 19th with a tiny 0.5m swell out of the S, period of just 4 seconds, and combined energy only 9. A 25 km/h cross-on wind makes it choppy and useless. Thursday and Friday are the same deal—minuscule, onshore and cross-on winds, energy barely hitting double digits. Small and gutless.
You get a little break Saturday the 22nd morning. The wind swings light cross-off from the W at 10 km/h, cleaning the surface up. The swell is still only 0.6m from the SSW, but it’s clean. Energy is still only 18, so it's knee-high at best. Sunday the 23rd morning is a repeat—clean with light W winds, but same tiny 0.5m swell. If you’re really jonesing, those two mornings are your only chances, but it’s just a paddle, not a surf.
From Monday the 24th all the way to Thursday the 3rd of September, it’s more of the same: sub-1.0m windswell, mostly from the S or SSE, periods stuck at 4 to 6 seconds. Energy never reaches 70. Most days have onshore or cross-on winds, and every entry says "poor surf conditions."
There’s one little moment on Thursday the 3rd morning with a light offshore breeze from the NNW at 5 km/h, making it glassy. But the swell is only 0.4m from the SE, period 5 seconds. You could float around on a longboard, but there’s no wave to ride. It’s clean, but flat.
The breakwater here is an "inconsistent" spot in the best of times, and right now it’s dead. Water temp from the first day is 31°C, a touch warmer than usual for late August, so it’s nice for a swim but not for a wave.
Bottom line: no good surf options in the whole 16-day forecast. This coast can go quiet like this—it’s a normal stretch of nothing. Don’t let it get you down; forecasts can turn around. For now, keep the wax dry and the board stored.

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.
