The Lowdown
Alright, this is Rusty, checkin' in from the 13th Ave South Surfside stretch. Let's get real about what's coming down the pipe.
Alright, honest truth? The next week and a half is a tough slog. We're looking at a long, dry spell with barely a ripple. The water temp is sitting at a comfortable 83°, which is pretty normal for this time of year, so at least the wait won't be cold. But from now until nearly the end of August, you're gonna be chasing shadows. Most mornings are clean, especially with those light cross-offshore winds, but the swell is just pathetic. We're talking tiny waves, mostly under 2 ft, with weak energy. The wind does go a bit onshore in the afternoons, chopping up what little is there. It's a real bummer.
There's a glimmer of hope around the 26th of August. The Wednesday morning shows a bit of a pulse with 3 ft swell from the S, with a clean cross-offshore breeze from the W. The energy is still only moderate, but it's the best we've seen. Then Wednesday afternoon, a tiny 1.0 ft SE swell rolls in, but with a long 14-second period. That groundswell energy is a tease, making the conditions "surfable but very ordinary." It's a hint of something better, but not quite there.
Then, as we roll into the last week of August and into September, things start to build. The swell picks up, with a 4 ft E swell on the 29th, and the wave energy gets into the moderate range. The catch? The wind is mostly cross-onshore, keeping it a bit messy. The first day of September wraps it up with tiny 0.7 ft waves. It's a bit of a nothing burger for the whole 16-day window.
The Best You'll Get: If you're desperate for a paddle, the Wednesday morning of the 26th of August is your best bet. It's the only day that offers a clean, cross-offshore breeze with a 3 ft S swell. The energy is moderate. It's not gonna be pumping, but it's the cleanest and most rideable wave in this whole forecast. The other days just don't have the combo of size and clean wind.
To be honest, for most of this period, the setup looks more suited for a kite surfer than a paddle surfer, especially on those days with stronger onshore wind and a bit of chop. The waves are just too small and weak for a good session.
