The Lowdown
Alright, Rusty here, let’s talk about what we’ve got for the next couple of weeks. Straight up, this is one of those outlooks where you might want to keep the board in the bag and find something else to do. The swell window is pretty quiet for Galveston - Flagship Pier, and the conditions are fighting us most days.
We’re looking at a long stretch of small, weak surf. The combined wave energy is mostly in the double digits, barely cracking 39 at best, which is just weak sauce. The water temp is gonna be about what you’d expect for mid-August, nothing weird there.
For the first week, from Thursday, August 13 right through to about Wednesday, August 19, it’s a real struggle. The swell is tiny, mostly around 1 ft to 3 ft, coming from the SSE or S with a short, weak period of 4 to 6 seconds – that’s pure windswell with no punch. On top of that, the wind is mostly cross-onshore or onshore, at 9 to 16 mph, making it choppy and messy. There’s a brief moment on Sunday morning, August 16, where the wind drops to a cross-off 3 mph and the water cleans up, but the swell is only 1 ft – barely a ripple. Monday morning, August 17, has a similar clean window, but again, just 1 ft of weak SSE swell. It’s not enough to get excited about.
Then we roll into a gap. From around mid-week through to the end of the month, the numbers just flatline. There’s really nothing to recommend until the very end. On Thursday, August 28, the morning shows a glassy, clean start with the wind swinging light out of the NW at 3 mph. The swell is a tiny 2 ft from the SSE, period still short at 4 seconds, and combined energy at a paltry 17. It’s the only moment in the entire 16 days that even looks surfable if you’re desperate.
Truth is, this is a blank run. There are no standouts, no solid swells, just a whole lot of small, onshore junk. If you’re a kiter, some of those afternoons with 16 mph winds might be more your scene, but for a surfer, it’s a hard pass. The forecast is pretty consistent in its emptiness, so don’t hold your breath. Things can change, but right now, it’s a waiting game.
Rusty.
