The Lowdown
Alright, Rusty here again, but I’ll give it to you in the old units for the imperial-heads.
The story’s the same: a long, dry spell to start. From the 8th of August all the way through the 12th, there’s zilch. Tiny, weak swell, and the wind is just not cooperating. It’s a big gap of nothing.
The first real chance comes on Thursday morning, the 13th of August. Swell is about 4 ft from the WSW, with an 11-second period. That’s a groundswell with some power – the combined energy is 292, which is solid. The wind is a light cross-offshore from the north, so the waves will be clean. The water temp is about normal for this time of year. This is the standout of the entire 16 days. Keep in mind the break is inconsistent, so you’ll be waiting for the sets, but they’ll be worth it. It’s a fairly exposed SW-facing spot, so that direction is what we want.
After that, it goes downhill. The afternoon of the 13th and the next few days get windy and the quality tanks. We get a bigger swell on the 17th and 18th, with waves reaching 5 ft to 8 ft, but the wind is a cross or cross-on shore, making it choppy and lumpy. The 18th sees the biggest surf at 8 ft, but with a short period of 8 or 9 seconds and a cross wind, it’s going to be a messy, ugly wave. That’s more for the kite surfers than us. The energy hits 954, which is a lot of power, but it’s wasted on bad conditions.
The very end, on Sunday morning, the 23rd of August, offers a small, clean option. We’ve got 3 ft swell from the WNW, but the wind is finally offshore from the NE at about 12 mph. It’ll be clean and rideable, but the period is a short 6 seconds, so it’ll be weak and a bit crumbly. Fine for a longboard, but not what that Thursday morning will be.
So, bottom line: Thursday morning, the 13th. That’s the one. The rest is a whole lot of nothing or a whole lot of mess.
Rusty, out.
