The Lowdown
Hey folks, Rusty here. Let's be straight: Galveston's got a tough row to hoe over the next 16 days. The outlook is basically a long stretch of flat, blown-out, or just plain tiny slop. There's nothing in the 16-day window that I'd call a proper surf session.
The entire run is filled with "poor surf conditions" and the wave energy is laughable. On Tuesday, September 8th, we're looking at 0.7ft of south swell with a 4-second period – that's just wind chop. The water's sitting at a warm 87°F, which is a touch warmer than normal for the time of year. Through Wednesday and Thursday, it's more of the same: 0.7ft to 1.0ft of weak, short-period junk from the ESE. The first week is a write-off.
We drag through into the second week, and there's a slight, and I mean *slight*, uptick. Around Saturday, September 12th, we see 3ft from the south with a pulse of energy hitting 30, but it's still short-period windswell and the wind is a moderate cross-onshore. By Monday, September 14th, we get 2ft from the SSE with 26 of combined energy. It's still poor. The best looking moment in this whole block is maybe the morning of Monday, September 21st. We see 2ft from the SE, but with a crisp cross-offshore wind from the NNE. That would finally clean things up a bit, but the swell is still tiny and weak (24 energy). For a breakwater that's inconsistent and needs a solid SE groundswell to work, this is a long, flat stretch.
Don't hold your breath. It's a blank run for Galveston, but that's the way it goes here sometimes. Forecasts can always change. Until then, the kites might have some fun in that afternoon cross-onshore breeze.
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.
