The Lowdown
Alright, let’s talk about what’s going on at Avalon 15th Street. The truth is, it’s a flat spell. Tiny swell, day after day, with hardly anything worth paddling out for. There’s no big standout, but I’ll break down the few moments that might get you wet.
Your first chance comes on the morning of Friday August 21st. A 2ft wave from the NE with a short 6-second interval, cross-off wind from the NNE at 9 mph, keeping it clean. The combined energy is weak at 35. It’s a beginner wave, so if you’re just starting out, that’s your best early window. Water temp is about normal for this time of year.
Saturday August 22nd is a mixed bag. The morning is a washout with rain and a cross-on easterly at 16 mph. But in the afternoon, the wind goes glassy – dead calm out of the north at just 3 mph. The swell is still tiny at just over 2ft from the ENE, period a sad 4 seconds, energy 38. It’ll be small and weak, but if you’ve got a longboard and just want to bob around in perfect glass, that afternoon is your cleanest option.
From there, it’s mostly flat into early September. Wave heights stay between 0.5ft and 2ft, with a mix of short and long-period swells. There are a few glassy or clean mornings, like Monday August 24th with a 0.5ft offshore from the WNW, and Tuesday August 25th with glassy conditions – but you’re looking at ankle-deep waves. The highest energy comes on the morning of Tuesday September 1st: a 1ft SE swell with a long 14-second period, cross-off wind from the WSW at 9 mph, clean surface, and energy hitting 60. That’s the best energy in the whole outlook. The long period might give it a little push for a longboard, but it’s still tiny. Crowds are possible here, so you might not have it to yourself.
Honestly, there are long stretches with nothing worth mentioning. If you’re not on a longboard, this setup – small swell and stronger onshores later (like August 31st with a 3ft S swell and 16 mph S cross-on) – looks better for a kite than a paddle.
Hang in there. These quiet runs happen, but the forecasts can change.
