Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a good look at what’s coming our way.

We’ve got a solid run of swell on the cards for Black Rocks Jetty, starting Wednesday morning. The water is sitting at 77°F right now, which is much warmer than usual for this time of year, so you can leave the thick wetsuit at home.

Wednesday morning kicks off with a clean 5ft SW swell, 12-second period, and a light NNW cross-off breeze. The energy is moderate (935) and the conditions are glassy. It’s a good start, but the real standout is Thursday morning. That’s the pick of the first week. Thursday morning delivers a solid 10ft SSW groundswell with a 17-second period and absolutely zero wind – glassy as a mirror. The combined energy is strong (4932). This is proper reef-swell. The long period will keep the lines clean and the sets wide apart, making paddling out easier. It’s a big one though, over 8ft, so this is for experienced surfers only. The optimum swell direction from the SW lines up perfectly here.

Thursday afternoon gets messy with a cross-on SSW wind at 12 mph, roughing things up. Friday is a write-off for paddling – the swell jumps to 13ft, but the wind is howling cross-onshore at 16 mph, with energy up around 8234. That setup looks more interesting for kite surfing than paddle surfing.

Saturday afternoon brings a turn back to glory. The swell drops to a solid 10ft SSW, 15-second period, and the wind dies to nothing – glassy again. Another excellent session for the experienced crew. Sunday keeps the quality going with a 7ft SSW swell at 14 seconds, glassy conditions, and moderate energy (1969). Very clean.

Monday morning sees the swell back down to 4ft from the S, 12 seconds, glassy, with light energy (497). It’s surfable and clean, but nothing to write home about. From Tuesday the 1st of September through to the 4th, the surf drops off a cliff. The waves are tiny – 1.0ft to 2ft – with very weak energy (as low as 72). We’re looking at a four-day gap with nothing worthwhile. The 17-second period swell on the 4th morning is just too small at 1ft to do anything with.

Then we get a pulse back. Sunday the 6th of September morning is a real standout for the second week. A clean 4ft SSW swell, 17-second period, glassy, with moderate energy (1407). It’s a beautiful long-period groundswell, perfect for this reef setup. Then Monday the 7th keeps it tidy with 5ft SSW swell, glassy, and excellent conditions for experienced surfers. Tuesday the 8th afternoon also looks good – 7ft SSW, 17 seconds, glassy, with strong energy (2692). That’s another expert-only session. Wednesday and Thursday the 10th stay clean and surfable, with the swell easing back to 5ft, still glassy, all the way through.

The best on offer is Thursday 27th August morning and Saturday 29th August afternoon. Both are glassy, solid groundswell, and powerful. Don’t sleep on Sunday 6th September morning either – that’s a long-range beauty. Crowds are “sometimes” an issue here, so with conditions this good, expect company.

This is a classic reef run. Get on it when the wind drops, and you’ll be smiling.

Rusty.
