The Lowdown
Alright, Rusty here. Let’s break it down in the old numbers.
Right now, we’re looking at a solid stretch of surf at this exposed reef break, but it’s going to be a mixed bag. The main player is a South-Southwest groundswell meeting a cross-offshore wind. The surface is clean, but those long-period swells—17 seconds apart—are making it a bit lully and fat, not exactly rippable for the average board.
The water is sitting right at 80°F, which is totally normal for this time of year.
The first few days, from Wednesday the 12th through the following Monday, the swell holds steady in the 6 to 7-foot range. The wave energy is strong, like 2857 on Wednesday morning, but the reports keep calling it “marginal.” Wind is from the ESE to SE at 12 to 15 mph. Thursday the 13th bumps up to around 8 feet, and by Saturday the 15th the wind drops to a light 9 mph, making the surface glassier. Still, nothing is really screaming “go” until the middle of next week.
The real standout, and this is the one to circle, is Wednesday the 19th of August. The morning is clean, but the afternoon flips to a true offshore breeze from the ESE at 12 mph. That’s paired with an 8-foot swell out of the SW and a 17-second period, meaning wave energy is pumping (3771). The report says “excellent surf conditions for experienced surfers,” and that’s the truth. That’s your best bet.
Thursday the 20th morning keeps that offshore wind and an 8-foot swell from the SSW, also rated “excellent.” That’s serious size, pushing into expert territory, so be smart. The wind picks back up by afternoon.
After that, into the third week, the swell drops to 6 feet on the 21st, then surges to 10 feet on Saturday the 22nd. That’s huge, powerful energy (4306), but all cross-off wind, so it’s going to be a wild mess. More of a kite-surfing day than a smooth paddle session. Then look to Tuesday the 25th afternoon – the wind is light at 9 mph, and the period jumps to 19 seconds (energy 3047). That’s a very long period groundswell; expect clean lines but long waits between sets, best for the reef.
Wednesday the 26th morning offers a reprieve, with calm 6 mph winds and 6-foot swell, getting a nod for “excellent” surf. It could be a nice, mellow session before the energy fades.
Circle the 19th afternoon and 20th morning. That’s your window. It’s an inconsistent spot, but when it lines up with that offshore, it’s a treat.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Airport Lefts 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.
