The Lowdown
Alright, let me level with you. The surf, or lack of it, is the story here. Looking at the next couple weeks, it's been a real dry spell. Don't expect much at all until about Friday, July 24th. That's over a week of flatness.
The only spot we got on the list is Surfside Jetty. It's an advanced, inconsistent wave, so it ain't for the faint of heart.
That first real chance comes up on Friday morning, July 24th. There's a 4ft swell from the S with a 14-second period. It’s got moderate wave energy (1017). Not bad, but it's a cross-onshore wind blowing at 9 mph, so it’ll be a bit bumpy. Water temp feels pretty average for July, so normal trunks or a springsuit.
The real standout window? That’s Sunday, July 26th, in the morning. The swell drops to 3ft from the SW, but the period jumps to 19 seconds – that’s super long period. That means big, organized lines. The wind is light and onshore at 6 mph, so the surface should be smooth. The energy is still solid (979). For a jetty break, those long groundswells can really line up. This is your window. It won't be huge, but the shape could be perfect.
After that, things get messy again with cross-breezes or the swell just not holding together. If you're keen, point your board at that Sunday morning session. Any other day, you're likely fighting the chop or waiting for a set that never comes.
Rusty.

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.
