The Lowdown
Alright, rusties, let’s get into it. We’ve got a solid run of surf coming our way at Black Rocks Jetty, but it takes a minute to warm up. The wait is short – just a day or so – then the fun begins and doesn’t really let up for over a week.
The water is sitting at about 77° right now, which is a touch warmer than normal for this time of year, so that’s a nice little bonus for the skin.
The real standout window kicks off Monday the 27th. We’re looking at a clean 6 ft swell out of the southwest, and with a period around 16 seconds you’ve got some decent ground energy rolling in. The wind is a light cross-offshore from the NNW, so conditions are going to be clean. There’s plenty of push behind it. This is going to be excellent for experienced surfers – the size is up there, so beginners should sit this one out. The swell direction is a touch south of the optimum, but with that long period and clean wind, it’ll still set up well for the reef.
Tuesday the 28th is another highlight, with morning glass (0 mph) and clean 4 ft swell from the SSW mixed with some bigger afternoon energy at 7 ft. The long period (19 seconds) in the morning will have the reef working nicely, but be aware that with that kind of period at a reef, the sets will be more defined and the lulls longer – makes paddling out a bit easier though.
From Wednesday the 29th through Friday the 1st of August, we get a repeated pattern of glassy to clean conditions with waist to chest-high swell, mostly in the 5 ft to 6 ft range. The energy stays moderate to strong, and the wind is pretty well behaved. Crowds are possible here sometimes, so it’s worth getting out early for the best of the glass.
By the second week, things start to drop off. The 4th of August brings a morning of glassy 4 ft surf that will be rideable, and the 5th of August has some clean 4 ft to 5 ft sets with very long periods (19 seconds). That kind of period loves a reef setup, so Black Rocks should be handling it nicely.
After the 7th of August, the energy fades and the wave heights drop under 3 ft. The last few days are ordinary – better for a paddle than a proper session, honestly. There’s a gap from there with nothing worth getting excited about.
Best bet? Monday the 27th is your one to circle. Big, clean, and powerful.
