The Lowdown
Alright, folks, Rusty here. Let's be straight up: this is a tough outlook for our local waters. We're looking at a long, long stretch of flat or near-flat conditions. There's a solid 10 to 12 day gap with basically nothing worth paddling out for, so don't hold your breath.
The first chance we get, and it's a real "if you're desperate" kind of chance, rolls in on Monday the 31st of August. Before that, it’s all tiny, weak slop. On Monday morning the 31st, we might see a tiny bump at Galveston - Flagship Pier. Swell is coming from the SE around 2ft, but with a short period of 5 seconds, so it's weak and gutless. The combined energy is only 23 (moderate), so don't expect any push. The one saving grace is a light westerly wind, keeping it clean. Later that afternoon, the wind swings southerly and picks up to 19 mph, turning it choppy and messy, but the swell bumps up to 3ft with a combined energy of 41 (moderate). It's still poor surf, but it's the best we've seen in this entire forecast.
Tuesday the 1st of September offers a similar story. A morning session with a weak 3ft SSE swell and a light onshore breeze. The water temp is about average for this time of year, so no surprises there.
Honestly, there is nothing to get excited about. The first week and a half are a total write-off. These conditions are more suited for a flat-water paddle or a kite if the wind is right, than a surf. The forecast can always change, but as it stands, leave your board in the car.
Rusty.
