The Lowdown
Alright folks, Rusty here. Let’s get straight into the outlook for Galveston. I’m looking at a pretty flat and uninspiring forecast for the 16-day run. The water’s sitting at about 88°, which is a touch warmer than we’d normally see for this time of year—one of those little quirks that doesn’t mean much when there’s no swell to paddle into.
The first surf recommendation comes in on Thursday, 18th September. But let’s be honest, the numbers tell a story of misery. Right through from the 2nd to the 14th, we’re looking at weak energy readings mostly under 20, with swell heights barely scraping 2 feet and periods sitting at a pitiful 4 to 6 seconds. Combined energy tops out at a measly 38 on the 10th afternoon—still very weak. Winds are mostly onshore or cross-onshore, often moderate to breezy, with a few pockets of glass but nothing to get excited about.
Thursday, 17th September morning offers the best we’ll see. It’s not saying much, but we get a modest 3 feet of ESE swell with a 5-second period and combined energy of 50. The wind is cross-shore and light, so it’ll be clean with a slight chop. That’s the standout, sadly. It’s not big, it’s not powerful, but it’s the cleanest and biggest we’ll get.
Tuesday, 15th September morning also deserves a nod—2 feet from the SE with a 6-second period, and a clean cross-offshore breeze from the NNE. Small and workable for a longboard or a foamie if you’re desperate.
Other than those two windows, the rest is a long, flat gap. From the 2nd right through to the 10th it’s all poor surf conditions, tiny windswell, and raggedy wind. There’s a period from the 11th to the 13th with some onshore wind and bumpy conditions, but nothing worth planning a session around.
Galveston is a breakwater setup—inconsistent and only for beginners when it’s small. With swell this little and period this short, it’s really just a splash. No standouts worth chasing. If you’re looking for something to do, this setup with 16 mph onshore winds and weak chop might be more interesting for a kite session than a paddle.
Stay patient, folks. The forecasts can change, but right now we’re in a dry spell.
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.
