Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Black Rocks Jetty.

The next couple of weeks are a real mixed bag, with some absolute gems hidden in the middle of the run, but you’ll have to sit through a few quiet spells to get the good stuff. Right now, the swell is building. Tuesday morning kicks things off with a 5ft S swell at 12 seconds, backed by 1530 of moderate combined wave energy, but that cross-shore wind from the SE at 6 mph is going to mess up the surface. That afternoon, things take a turn for the heavier: the swell jumps to 10ft from the S on a 12-second period, energy cranks right up to 3922, and the wind goes light cross-off from the ESE. This is big, powerful, expert-only territory here – way too much water for a beginner.

Wednesday, the swell drops back to 5ft in the morning, but you’ve got a poor onshore wind from the SW, so that’s a write-off. Wednesday afternoon though is a nice surprise – the swell drops to 4ft from the S, but the wind goes glassy from the NW, so despite the small size, the surface is clean. Thursday and Friday morning stay small with 3ft swells but with glassy conditions, and a really juicy development on Friday afternoon: a 4ft SW groundswell with a long 14-second period, glassy SSE wind, and 543 of energy. That’s going to feel a lot better than the height suggests.

Now for the real standout. Saturday the 11th morning: 5ft SW swell, 15-second period – that’s proper long-period groundswell – combined with a glassy WSW breeze and 1077 energy. At a reef like this, that combo means juicy, lined-up waves. Sunday the 12th morning, it gets even bigger: 8ft SW, 15 seconds, and 2425 energy, with glassy SW wind. That’s the pick of the whole run for experienced surfers, but at that size, beginners stay out of the water. Monday the 13th keeps the quality high with 6ft to 6ft SW groundswell and either glassy or calm winds all day.

The water temp is sitting at 77°F, which is a touch warmer than normal for this time of year, so no need for a thick wetsuit.

After that, the second week of the month fades. You get a few more clean mornings around the 14th to the 17th with 3ft to 5ft SSW swells and light offshores or glass, but the energy drops, and by the 18th it’s barely 2ft with onshore wind. There’s a faint pulse again on the 20th and 22nd with 4ft long-period SSW groundswell and glass, but it’s not the same power as that killer stretch around the 11th to 13th.

Overall, the absolute best on offer is Saturday 11th and Sunday 12th mornings – big, clean, long-period SW groundswell, light winds, and plenty of grunt. Get in the water then.

Rusty.
