The Lowdown
Gather 'round, folks. Rusty here. We've got a solid 16-day window ahead, and it's all about one spot: Yo Yo's-The Wedge. This is a heavy, advanced reef break that's very consistent, so it's not for the faint of heart. The water temp is sitting at 80°F, which is just about spot on for this time of year. There's a big gap right now with no surf worth mentioning before the first solid call.
Let's start with the peak of the action. The standout window kicks off on Wednesday, August 19th. Wednesday morning is the real gem. We're looking at a clean 8 ft swell from the SW, with a very long period of 18 seconds. The wind is glassy, literally 3 mph from the SSE. For a wave like this, that's a dream scenario. The combined energy is a massive 3627 (moderate-to-strong). This is best for experienced surfers only. The swell direction is a perfect match for the optimum SW, and the conditions are primo. Wednesday afternoon sees the wind pick up to 12 mph, turning it cross-off, but it stays clean. The swell is a touch bigger at 8 ft, and the energy is even higher at 4090.
Thursday, August 20th, is another top-tier day. Thursday morning has clean 8 ft SW swell with a 16-second period and cross-off wind from the SE at 9 mph. The energy is 3868. It's a killer session. Thursday afternoon, the wind picks up to 12 mph, but it's still a clean, cross-off situation.
Friday, August 21st, is still very good. The morning has a clean 6 ft SW swell with a 15-second period, and the energy is 2367. The wind is a gentle 9 mph cross-off. The afternoon sees the swell bump back up to 8 ft with a 17-second period and 3172 energy, but the wind is a stiffer 16 mph. Still, it's cross-off and clean, so there are waves to be had.
From Saturday, August 22nd, through the rest of the week, the swell drops a touch, hanging around the 5 ft to 7 ft range. The wind stays mostly cross-off or cross from the SE, but it's consistently blowing 16 mph or more. The energy is moderate, ranging from 1463 to 2516. The conditions are clean, but it's a bit more of a wind-swell situation. It's not the highlight, but it's still surfable for the experienced crew.
There's a drop-off on Thursday, August 27th, with swell down to 3 ft and a cross-shore chop. Not great.
But then, we get a second puff of life. Friday, August 28th, brings a fresh pulse of 8 ft SW swell with a 16-second period and 3067 energy. The wind is a gentle cross-shore, so it's a bit bumpy but still a solid option for the advanced surfer. This continues into the start of September.
The final standout is on Tuesday, September 1st, and Wednesday, September 2nd. Tuesday morning has a clean 8 ft SW swell with a 17-second period and 3008 energy. The wind is a cross-off 16 mph. Wednesday morning is even bigger, with a clean 8 ft swell and a massive 3818 energy. The wind is still cross-off at 16 mph. These are excellent, powerful days for the experts.
A quick note on the long period swells (over 15 seconds). Yo Yo's-The Wedge is a reef, so it handles those long-period groundswells beautifully. It won't be as straight-breaking as a beach break. The long gaps between sets will make paddling out a bit easier, but the sets themselves will be heavy.
Crowds at Yo Yo's-The Wedge are often busy, so expect company.
Overall, Wednesday morning the 19th, Thursday morning the 20th, and Wednesday morning the 2nd of September are the absolute standouts. The rest is a solid run of clean, powerful, expert-only waves. If you're not an advanced surfer, this entire forecast is a no-go. The swell is consistently over 5 ft, and often over 8 ft, which is expert territory.
Rusty, signing off.
