Black Rocks Jetty Surf Forecast and Surf Report

Righto, let's have a look at what's on the table here. We're looking at Black Rocks Jetty, a reef break that's exposed to the southwest. Water temp is sitting about average for this time of year, so nothing out of the ordinary there. This spot is very consistent, so there's rarely a dull moment.

We start off this Sunday morning with a bit of a dud. There's a small 3ft SW swell, but the wind is a cross-on from the south, so it's messy. The combined energy is weak at 457. Not worth paddling out for.

Monday the 20th is when things kick off. Holy moly, Monday morning we've got 7ft of SSW groundswell with a 14-second period, and it's glassy – dead calm. The energy reading is a solid 1987, which is strong. This is excellent surf, but at that size, it's strictly for experienced surfers. The afternoon holds 8ft with the same glassy conditions. That's the standout window of the whole run. Clean, powerful, and pumping.

Tuesday the 21st eases a touch to 6ft in the morning with a light north cross-off breeze, keeping it clean. The energy drops a bit to 1102, but still moderate. The afternoon gets a little cross-shore chop. Wednesday the 22nd is another beauty morning – 5ft of S swell with glassy conditions. The energy is 967. This is very good, clean surf.

Thursday the 23rd and Friday the 24th have smaller swell around 3ft to 4ft, and the winds get a bit onshore and cross-shore, so it's more marginal. Saturday the 25th looks cleaner again with glassy mornings, but the swell drops back to 4ft.

Now, hold onto your board for the end of the month. Sunday the 26th afternoon, we see a massive 5ft SW swell with a 20-second period, but the energy jumps to 2352. The wind shifts glassy, so this is a long-period groundswell. Be aware that this kind of swell can be tricky at a beach break, but at a reef like Black Rocks, it's going to be lined up and heavy. For experts only.

Monday the 27th and Tuesday the 28th are absolute crackers. We're looking at 7ft to 8ft SSW swells with 15-16 second periods, and the mornings are glassy. The energy is through the roof, over 2400. This is serious, powerful surf. The crowd situation? It says "sometimes", so expect a few people out, but it's worth it.

Wednesday the 29th afternoon looks like the absolute peak. An 8ft SSW swell with a 16-second period, glassy conditions and a combined energy of 3792. That is a massive, powerful, clean swell. This is the one to circle on the calendar. If you're advanced, get in the water. If you're not, stay on the beach and watch.

The first few days of August keep the run going. The 30th and 31st still hold big 7ft to 8ft swells with glassy mornings, though the afternoons get a little onshore. Saturday the 1st of August starts with a glassy 6ft but the swell period drops to 12 seconds. Sunday the 2nd comes back strong with 8ft and glassy conditions. The run finally fades on Monday the 3rd with some onshore wind.

So overall, there is a serious run of swell here. The absolute standout is Wednesday the 29th of July afternoon – 8ft, 16 seconds, glassy, and a combined energy of 3792. Monday the 27th and Tuesday the 28th are also world-class. For a more manageable but still excellent session, Monday the 20th is the first big day. This is a reef break, so the long-period swells are going to suit it perfectly. Keep an eye on the crowd, but for the experienced surfer, this is a golden run.
