The Lowdown
Alright team, Rusty here with the lowdown on the local surf.
We’ve got a solid run of swell coming in, but the conditions aren't perfect across the board. Water temp is about 80°, which is right where it should be for this time of year.
The clear standout is the morning of Thursday, August 20th, at Yo Yo's-The Wedge. We’re looking at a stout 8ft SW groundswell, with an extra-long period of 16 seconds, pumping out a massive 3723 units of energy. The wind is a light 9 mph cross-off from the SE, keeping the surface clean. It’s a powerful, clean wave, but this is a reef break that’s very consistent, and at that size, it’s for the experts only. The afternoon holds similar size and energy, but the wind picks up a bit.
Friday the 21st and Saturday the 22nd still have decent pulse, with swells around 6ft to 8ft from the SW and SSW, but the moderate cross-off winds are a little stronger, making it feel less special than that first morning. The energy is still impressive though.
We see a steady drop in size through the end of August and into the first week of September. The energy readings dip into the three-digit range by the 27th, and the wind starts to swing more cross-shore, bringing in some chop. There’s a little blip on the 31st of August where the swell period jumps back to 20 seconds, which is a very long period groundswell, but the heights are only 6ft, so it’ll be more about the shape than the power.
Looking further out, the first couple of days of September offer a glimmer of hope. The morning of Tuesday, September 1st, has a gentle breeze and clean conditions on a 7ft SW swell, and the afternoon of Wednesday, September 2nd, looks excellent with a light 6 mph breeze and clean surf for experienced surfers. These are the most promising calls in the second week, but as always, that far out, we’re keeping a hopeful eye on the sky.
Overall, the best bet is to get on it Thursday morning, August 20th, for the biggest, cleanest, and most powerful waves on offer.
