The Lowdown
Alright, this is Rusty. Let’s see what Black Rocks Jetty has in store over the next couple weeks.
The first few days are looking real promising with clean southwest groundswell and light offshore winds. Thursday morning the 13th starts with a clean 4ft from the southwest at 13 seconds – not huge, but the water is a touch warmer than usual at 77°, and with glassy conditions, it’s a nice way in. The combined energy is moderate at 363.
The real standout is Friday the 14th. Morning brings 6ft from the south-southwest, 13-second period, glassy – combined energy of 1175, moderate. That afternoon it jumps to 1620, still glass. Excellent, clean surf for experienced surfers. Saturday the 15th afternoon is the peak of the first week: 7ft, south-southwest, 18-second period – that’s a long-period groundswell – and glassy with combined energy of 5094. For a reef break that’s very consistent and exposed to the southwest, this is the session. Sunday the 16th morning is also exceptional, with 8ft and glassy. That’s big, clean, expert territory.
The swell eases into Monday the 17th and Tuesday the 18th, but stays clean with 3–4ft waves, glassy. Crowds are possible at this spot sometimes.
Wednesday the 19th and Thursday the 20th go small – around 2–2ft – still glassy but not worth the paddle. Then building again Saturday the 22nd afternoon: 8ft south-southwest at 12 seconds, glassy, combined energy 3338 – solid. Sunday the 23rd keeps 7ft at 14 seconds, glassy.
The next big highlight is Tuesday the 25th of August: 7ft south-southwest at 17 seconds – very long period groundswell. Combined energy of 2395. For a reef, that’s real quality, and with glassy conditions, it’s a prime day for experienced surfers.
The very end – Wednesday the 26th – shows a massive 12ft swell from the south-southwest, but the wind turns cross-onshore. Combined energy of 6210 – that’s strong. That one looks more interesting for kite surfing than paddle surfing unless you’re an expert. Thursday the 27th afternoon cleans up with 5ft and glassy, then Friday the 28th finishes with smaller, wind-affected waves.
Best on offer: Saturday the 15th afternoon for the big, clean, long-period swell. Friday the 14th and Sunday the 16th are excellent too. Tuesday the 25th is another one to mark. That’s the word.

Information about the Black Rocks Jetty Surf forecast
