The Lowdown
Alright folks, Rusty here. Let’s take a good, long look at what’s on the menu for the next couple of weeks, and I’ll be straight with you – it’s looking pretty grim.
We’ve got a solid 16-day window ahead, but don’t get your hopes up. The first surfable day worth mentioning doesn’t even kick off until Monday, the 10th of August, and even then, it’s a rough start. The whole run is essentially a series of tiny, weak swells with poor conditions. The combined wave energy barely gets into double digits most days, sitting in the weak range (under 100). The water temperature is sitting at 87°F, which is about 2°F warmer than usual for this time of year, so it’s a warm bath out there, but that’s about the only nice thing I can say.
Monday, August 10th through to Sunday, August 16th is a total write-off. We’re looking at surf heights of 1ft to 3ft max, all from the south or southeast. The period is a pathetic 4 to 6 seconds, meaning no power, no shape. The wind is a constant problem – mostly cross-onshore or onshore, building from a light breeze up to a moderate breeze. It’s choppy, bumpy, and just plain ugly. There’s one brief moment on Sunday morning, August 16th where the wind goes light and cross-offshore from the northwest, giving us a clean look at the 1ft SSE swell, but it’s so small it’s barely a ripple.
The next week, Monday, August 17th through to Tuesday, August 25th, doesn’t get any better. Swell heights stay stuck between 0.3ft and 2ft, with the same short, weak periods. The wind is a mess of onshore and cross-onshore flows. There are a couple of clean moments – like Monday, August 24th morning with a light offshore from the northeast, and Tuesday, August 25th morning with a light offshore from the northwest – but with the swell being so tiny (2ft and 2ft respectively), it’s still just ankle to knee-high slop. The combined energy never breaks 30, which is incredibly weak.
Galveston itself is a breakwater setup, and it’s inconsistent. Given the persistent onshore winds and tiny, weak swell, this setup looks more interesting for a kite surfer looking for a bit of wind than for a paddle surfer. For the rest of us, it’s a flat spell.
There’s no standout day here. The best you can hope for is a clean, glassy morning on the 25th of August, but even then, the swell is only 2ft from the SSE. It’s not worth a paddle.
Rusty, signing off.

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.
