Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here with the full lowdown for Black Rocks Jetty.

We've got a solid stretch of surf on the cards, but it’s a mixed bag with a couple of absolute standout sessions if you time it right. The water’s sitting at a warm 75° which is about average for this time of year, so no need to dig out the thickest wetsuit just yet.

The overall pattern starts with a bit of a rough patch. Sunday morning kicks things off with a 5ft SSW groundswell, but that cross-on wind has the surface a bit messy. It's surfable, but not the best of the run. The real action starts to build through the week.

Tuesday the 15th is where we see the first real gem. After a pretty average Monday, Tuesday afternoon turns it on. The wind drops to glassy, dead calm, and we’ve got a solid 6ft of SSW groundswell with a very long 17-second period pushing in. The wave energy is pumping (2002) and that combo of size, period, and perfect conditions will have Black Rocks looking exceptionally clean and powerful. This is a serious standout for experienced surfers.

Then we get another big hitter on Wednesday the 16th. The morning sees a bigger 8ft SSW swell (2999 energy) with an onshore wind, making it a bit raw and only for the brave. But hold out for Wednesday afternoon – the swell drops slightly to 8ft, and the wind goes glassy again. That’s a huge, clean swell with a 14-second period. Again, this is expert-level territory with that size, but the quality will be world-class if you can handle it.

After those two peak days, the surf settles down. We get some clean, smaller days through the end of the week and into the weekend. Thursday the 17th morning offers a fun 5ft S swell with glassy conditions, a good session for a wider range of surfers. Friday and Saturday see the swell drop off to under 3ft, though the winds stay favorable with some glassy windows.

Looking further ahead into the final week of September, the swell starts to build again. The standout from this longer-range period looks like Monday the 28th of September. It’s still a week and a half away, so take it with a pinch of salt, but the forecast shows a glassy afternoon with a 3ft SSW swell carrying a very long 18-second period. That kind of period on a reef like Black Rocks will produce some gorgeous, lined-up waves, even if the height is modest. The energy reading (936) backs that up – it’s quality over quantity.

Best on offer: Tuesday the 15th afternoon and Wednesday the 16th afternoon are the clear standouts for the experienced crew. For the rest of us, don’t sleep on that Monday the 28th afternoon session.

Keep an eye on the tides, because with a reef setup like this, they’ll make or break the session.

Stay wet,
Rusty
