The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Surfside Jetty is lookin' real flat. There's a gap at the start with nothing at all on offer, and honestly, the whole run is a struggle.
We're looking at a pretty grim stretch. There's no real surf to get excited about. The water temperature is a very unusual 72°F, which is much warmer than normal for this time of year – practically bathwater, but that's about the only highlight. The first sniff of anything is on Thursday the 17th of September, but even that is just a marginal morning with a tiny 2 ft swell from the SSW (moderate wave energy of 269). It's marginal surf with questionable tide conditions. The wind is light onshore from the SW, so it won't be clean.
From there, it's a long, flat slog. You'll see that tiny 2 ft to 3 ft swell from the SW sticking around for days, but it's always crossed up by onshore or cross-onshore winds. The energy is moderate in the water (sometimes around 300 to 500 range), but the quality is just poor. Every day is a write-off with "poor surf conditions" annotations. There are a few mornings with light winds, like Friday the 19th, but the swell is too weak and the wind is still cross-onshore, giving it small ripples.
The consistency is non-existent here. It's an inconsistent break at the best of times, and right now, it's barely even registering. There are no standout days. No best on offer. This is one of those periods where you dust off the longboard or find something else to do. The forecasts can always change, but for now, this is a blank run that's pretty normal for a quiet spot like this. Even for a big wave spot, the setup here looks more interesting for a kite surfer than a paddle surfer.
Stay positive, but don't hold your breath.

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.
