Table - best surf conditions forecast for Yo Yo's-The Wedge over the next 16 days.
The Lowdown
Alright, let's break it down. Yo Yo's-The Wedge is a reef break for advanced surfers, and it’s real consistent when the swell hits. Water temperature is about 80°, which is normal for the time of year.
We’ve got a slow start. Tuesday 18 August morning is weak—4ft from the SSW, but cross-on wind kills it. Energy is low (1961). Not worth it. That afternoon, the swell bumps to 5ft from the SW, wind goes cross-off, and it cleans up nicely. The energy jumps (2428). This is where it starts to get interesting.
Wednesday 19 August is the big one. Morning sees 8ft from the SW, cross-off wind, and energy pumping (3607). That afternoon hits 8ft (4087). That’s expert territory. Period is 18 seconds—long period groundswell, perfect for a reef. This is the best session of the whole forecast.
Thursday 20 August holds at 8ft but the wind goes cross-shore in the morning, with some chop. Afternoon cleans up again. The rest of that week stays in the 6 to 8ft range, with cross-off wind mostly, but the wind picks up to 25 mph later on.
From 24 August onward, the swell drops to 5-6ft, still SW, but energy and quality fade a little. Not terrible, just not the peak.
Into September, Tuesday 1 September shows another spike—7ft in the morning, 8ft in the afternoon, period 17 seconds, strong energy (3343 and 3554). Wind is cross-shore, so a bit of texture, but solid surf. Wednesday 2 September drops back but still worth a paddle.
The absolute standout is Wednesday 19 August. That’s the one. The early part of September is a solid backup.
Rusty.
