The Lowdown
Alright folks, Rusty here. Let's get straight into it for the local stretch.
Honestly, for the next 16 days, it's a tough beat. We're looking at a real flat spell. The very first window of surf isn't even worth paddling out for, and it stays that way for the entire run. We're talking about a long stretch of tiny, wind-affected slop with no real energy behind it. The combined swell energy is in the single digits and low teens, maxing out at a weak 39, which is just sad. The swell is coming from the south and southeast, but with periods of just 4 seconds, it's pure windswill, not a wave to get excited about.
The only break on the radar for the whole period is Galveston - Flagship Pier (Galveston-Flagship). It's a beginner-friendly beach and pier setup that's often crowded, but with no surf, that's a non-issue. The water temperature is sitting at 87°, which is a touch warmer than normal for this time of year.
Let's run through the days. Nothing at all on offer for the 20th or 21st, just tiny, choppy junk. The 22nd and 23rd have some cleaner mornings with light offshore winds, but the swell is still only 1 ft. It's clean, but flat. This same pattern of tiny, clean mornings and choppy afternoons drags on through the 24th, 25th, 26th, 27th, and 28th. The swell never gets over 2 ft, and the period never gets over 5 seconds. It's a total write-off for anyone wanting to get a wave.
The last few days of August and into September are the same story. The morning of the 1st of September actually has glassy conditions, but the swell is only 1.0 ft. It's pretty, but flat. The wind shifts on the 3rd of September, with a stronger onshore flow from the southeast, but the swell only bumps up to 3 ft with a 5-second period. The combined energy is still a weak 39. It's a poor, choppy mess.
The bottom line is there's no standout, no best option, nothing. Every single entry in the forecast is marked as "poor surf conditions." For a spot that's fairly consistent, this is a rough run. But it won't stay this way forever. For now, keep the board in the car and wait for the next pulse.
Rusty.
