The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening at 13th Ave South Surfside. I’m gonna be straight with you – the next couple of weeks are a bit of a struggle. There’s nothing that’s going to get the heart racing, and it’s a long wait for anything worth paddling out for.
The first real chance we get is on the morning of Tuesday, 18th August. The swell is tiny at 1 ft from the SE, but the real story is the wind. We’ve got a light cross-offshore breeze from the NNE at 3 mph, which will clean the surface right up. The combined wave energy is pretty weak at 48, so don’t expect any power. It’s surfable, but you’ll be working for every little bump. This break is inconsistent at the best of times, so this is a true "beggars can’t be choosers" situation. The water temp is sitting at 84°, which is pretty average for this time of year, nothing unusual there.
After that little window on the 18th, things go flat and messy again. Most of the other days are plagued by onshore and cross-onshore winds, with swells barely reaching 1 ft and short periods under 10 seconds. It’s mostly choppy, bumpy, and just not worth the effort. We’re looking at a big gap with no real recommendations through to the end of the month.
The very last day in the forecast, Thursday, 27th August, offers a tiny glimpse of something, but it’s still just 1 ft from the SE with a moderate onshore breeze. Not a stand-out by any stretch.
Honestly, for this area, a run of flat and poor conditions like this isn't unusual. It’s a quiet spot. If you’re desperate for a slide, that Tuesday morning on the 18th is your only real shout, but keep the expectations on the floor.
