The Lowdown
Alright folks, let me level with you. The surf scene is looking bleak for the next couple of weeks.
From Sunday the 13th right through Thursday the 17th, don't even bother. We're starting with a risk of thunderstorms, an onshore SSE wind blowing 12 mph, and a tiny 2 ft swell with a short period of 5 seconds. The wave energy is a pathetic 14. It's just poor conditions. This pattern of small, choppy, onshore wind holds all week. The wind goes cross-onshore from the ESE, ruining that 2 ft to 4 ft swell into complete chop. The energy does climb to 77 by Thursday morning, but it’s still blown out by that stiff 16 mph ESE breeze.
We finally get a tiny window on Friday the 18th. The morning looks clean. The swell is a bit better at 4 ft from the ESE with a period of 6 seconds, and the big change is a light NE breeze at 6 mph, giving us a cross-offshore flow. The combined energy gets up to a moderate 133, and the report says it's clean. The water is a balmy 87°F, a touch warmer than average for this time of year. It’s still weak and the direction is average, but it’s the only shot at "surfable waves" in the whole outlook.
After that one Friday morning, it’s game over. The rest of the 16-day window is flat. We're looking at 0.6 ft to 2 ft from the SE for days on end, with onshore or cross-onshore winds. We get a taste of offshore from the NNW on Tuesday the 22nd, and even a glassy morning that day with a 3 ft E swell, but the period is only 3 seconds and the energy is just 26. It's not enough to get wet for.
For a spot like Galveston, this kind of dry spell is normal. It’s an inconsistent break, and with the swell stuck coming from the SE, it just doesn't have the right exposure to pull in anything solid. Don't get too down, though; forecasts can change.

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.
