The Lowdown
Alright folks, Rusty here. Let’s be straight up – the next 16 days for the Galveston area are a brutal stretch of flat, blown-out nothingness. There really isn’t a single standout session worth paddling out for. We’re looking at a long, dry spell with barely a ripple. The water temp is sitting at about 87°, which is a touch warmer than normal for this time of year (water temperature anomaly 3°F), but that’s about the only thing worth noting.
Right from Monday the 14th, it’s ugly. We’ve got a tiny 2 ft south swell with a weak period of 5 seconds and only 18 units of energy. To make it worse, there’s a risk of thunderstorms and an onshore breeze. That’s a hard pass. Tuesday the 15th is even smaller at 1 ft, and the wind stays on it. Nothing changes through Wednesday the 16th or Thursday the 17th, though Thursday does see a bump to 3 ft out of the ESE, but with a fresh cross-onshore wind at 18 mph making a lumpy mess. The energy nudges up to 81, but the quality is still rated as poor.
Friday the 18th through to Sunday the 20th offer no relief. Swells stay below 3 ft, winds are cross or cross-onshore. Sunday morning the 20th does go completely glassy for a moment with 1.0 ft, but there’s no energy in it (8 units). After that, from Monday the 21st all the way through to Tuesday the 29th of September, the swell completely flatlines. Most days show wave heights of 0.3 ft to 1.0 ft. Even though we get some clean, cross-offshore winds from the north around the 22nd and 23rd, there’s simply no swell to ride. The energy readings drop to single digits – we’re talking 1 to 7 units. It’s a total bust.
For a breakwater setup like Galveston that’s already inconsistent, this kind of blank run isn’t totally out of the ordinary for the area. But it doesn’t make it any less frustrating. Don’t waste the gas. The forecasts can always change, but right now, there’s zero to report.
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.
