The Lowdown
Alright, let me level with you. This is a tough one. I’m looking at the next couple of weeks and honestly, we’ve got a rough patch ahead.
15th Street is a consistent, exposed beach and reef break that usually has something, but for the next ten days or so, it’s going to be a real struggle. The water’s sitting at 77° right now – that’s much warmer than normal for this time of year, which is nice for a paddle, but it doesn't help the waves.
We start off on Thursday the 6th of August with a tiny 2ft SW groundswell, period around 13 seconds, but the wind is straight onshore from the west. The combined energy is weak, around 139, and it’s just poor. That theme holds through the weekend and into the next week. The swell stays small, mostly between 2ft and 3ft, and while it's a long-period SSW groundswell – which usually means better shape – the onshore and cross-onshore winds from the west and southwest are just wrecking it. It’s choppy, it’s messy, and honestly, not worth suiting up.
There’s a gap here with no real recommendations. It’s not until Tuesday the 11th that we see a glimmer – a 1 out of 10 on the afternoon. The swell picks up slightly to 2ft from the SW with a solid 18-second period, and the wind finally goes light and offshore from the WNW. That’s the best call in this whole period, but it’s still marginal. The combined energy hits 469 (moderate), but it’s a one-off.
The following days through to the 20th of August are more of the same: small, wind-affected, and poor. The swell height nudges up to 4ft on Saturday the 15th with a 16-second period and light offshore winds – that’s the only other standout. The energy gets up to 783 (moderate), so there’s some push, but the overall quality is still rated marginal. It’s the best of a bad bunch.
Honestly, if you’re desperate, aim for the Tuesday 11th afternoon or the Saturday 15th. But don’t expect much. The setup here is more interesting for a kite surfer than a paddle surfer on most of these days. Keep an eye on the forecasts, though – it tends not to stay this poor for long.
