The Lowdown
Alright, let’s talk about what’s brewing.
We’ve got Yo Yo’s-The Wedge, a heavy reef break that’s only for advanced surfers. It breaks very consistently and can get crowded. The water temp is about 81°F, which is right around normal for this time of year.
For the next week, it’s a bit of a mixed picture. The wind is a constant cross-off from the SE, keeping the surf clean, but the wave quality is often described as marginal. The swell is coming from the SW – exactly what this spot wants – and the energy levels are moderate to strong, with combined energy readings in the 900 to 1300 range early on. The swell size sits around 4ft to 5ft through Saturday the 18th and Sunday the 19th, with a solid 14-second period. That’s proper groundswell, which on a reef will line up nicely.
The best session in the first week is Monday morning, 20th July. The swell climbs to 6ft, the period goes to 17 seconds, and the combined energy hits 2349 – that’s strong wave energy. The wind is blowing 30 km/h cross-off, keeping it clean. That’s the one to aim for. Tuesday the 21st is still decent with 6ft and 14-second period.
There’s a bit of a drop through Wednesday and Thursday, with the swell falling to around 3ft. Then on Sunday the 26th of July, the morning shows a 6ft swell from the SE, but the period is a short 8 seconds – that’s windswell, not the same quality. The energy is only 944, so it’s moderate.
Looking at the second week, things pick up. Tuesday the 28th of July morning has 4ft, but the period jumps to 18 seconds and the energy is 1657. That’s promising. Wednesday the 29th is similar, with 6ft and 15-second period.
The big one is Saturday the 1st of August. That morning shows 8ft of SW swell, with an 18-second period and combined energy of 4585 – that’s strong to very strong wave energy. That’s a massive, powerful groundswell. The wind is 30 km/h cross-off, so it’ll be clean. But 8ft on a reef is for experts only – it’s going to be heavy and critical. Sunday the 2nd of August still has 8ft and 17-second period.
The standout sessions are Monday the 20th of July morning for the first week, and then Saturday the 1st of August morning for the real energy. That August 1st swell is the biggest, longest-period swell of the entire 16-day run, and it’s from the ideal direction. Just be ready for the crowd, because this spot is often busy.

Further information to help with frequently asked questions about our surf forecast for Yo Yo's-The Wedge 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.
