The Lowdown
Alright, Rusty here, breaking down the Galveston outlook for the next couple of weeks, in feet.
To be honest, the first week and a half is a total dud. Tiny waves, onshore wind, and plenty of chop. No point getting your hopes up until Sunday, September 6th.
That morning, on the 6th, we finally see a little life. A 2 ft swell from the southeast, but the wind is blowing light offshore from the northwest. That makes all the difference – it’ll be clean and glassy. The combined swell energy is weak (44), so it’s not a power session, but you’ll get some fun little lines. Water temp is about normal for the season.
By the afternoon, the wind changes and it gets messy again, so it’s strictly a morning session. The next morning, Monday the 7th, has a touch more size – around 3 ft – but it’s onshore and choppy, so nothing special.
The one to really watch is the morning of Saturday, September 13th. That’s the standout. A light offshore wind from the northwest, with a 2 ft swell from the southeast. The swell direction isn’t perfect, but that offshore breeze is the key. It’ll be clean and glassy. The energy is tiny (13), so it’s a longboard or fun-shape day, but that’s the cleanest wave of the whole 16-day run. It’s a long way out, so the forecast might shift, but as it stands, that’s your best bet.
The rest of the time, the swell is small and the wind is trash. Nothing over 3 ft, and even that’s only for a couple of hours. Beginners will be fine with the size, but the onshore winds will make it messy. Honestly, mark those two mornings – September 6th and September 13th – and forget the rest.
Rusty.

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.
