The Lowdown
Alright, let’s break it down.
To be honest pal, Surfside Jetty is looking like a mostly flat, blown-out mess for the better part of two weeks. There’s a big stretch of nothing worthwhile from now through the 25th, so don’t even bother checking the cams until the very end of the window.
The first week and a half is a write-off. Swell hangs around 1ft to 3ft with periods from 13 to 18 seconds – long period groundswell, sure, but there’s no height to work with. Winds are blowing onshore or cross-onshore from the SW and WSW all day, so it’s choppy and messy. Water temp is 70°, which is about 3° warmer than average for the time of year – a touch warmer than normal, but that’s about the only plus. The combined energy is weak to moderate, reading between 100 and 480 – nothing to write home about.
The only two standout windows are the mornings of August 26th and August 28th. On Wednesday the 26th, we get a jump of swell from the S at 6ft, period 13 seconds, with a strong energy reading of 1281 – that’s expert territory. Wind is light cross-onshore from the SSW at 6 mph, so it’ll be a little bumpy but doable. On Friday the 28th, the morning session offers 4ft from the SSW, 12-second period, energy at 751. Wind is light onshore from the SSW at 6 mph. Expect a bit of texture but still rideable.
This spot is inconsistent and rarely breaks properly, so when it does, it gets attention. Crowds are often a factor. The break is fairly exposed to swell, but the quality is almost always poor or marginal.
So you’ve got two mornings to maybe get a couple of waves. The rest is a beach day. Keep your hopes low and your eyes on the horizon.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Surfside Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
