The Lowdown
Hey, it’s Rusty. Let’s talk about ADs/Doubles.
Truth is, the next week and a half is a bit of a grind. The wind is locked in from the ENE, blowing cross-shore at 25 to 28 mph most days, and that’s just messing up the surface. There’s plenty of energy in the water – the combined swell energy runs between 1187 and 1518 (moderate to strong) – but it’s all short-period, junky stuff. The water is 80°, which is about normal for this time of year.
We’ve got a long stretch of poor or marginal surf. From Friday the 24th all the way through to Tuesday the 29th, the morning and afternoon sessions are all getting a failing score for quality. The swell direction is all over the place, but the wind is just too strong and too cross-shore to let anything shape up. The one real exception comes on Wednesday the 29th of July.
The standout is Wednesday morning, the 29th. The wind shifts to the WNW, dropping to a light 6 mph and going offshore. That’s a huge change. The swell jumps up to 12ft from the NE, with a period of 11 seconds. The combined energy hits 3333 (strong). Now, 12ft is serious size – for experts only, no question. The offshore wind should make it glassy, but that’s a lot of water moving. The forecast says the wind and tide are favorable, and that’s the only window in this whole run that looks genuinely good. If you’re an experienced surfer and you can make it, that’s your session.
After Wednesday morning, the wind goes back to the cross-shore and cross-onshore pattern, and the quality drops off again. The rest of the 16-day window is more of the same – poor conditions, short-period swell, and messy onshore wind. No other standouts in the second week.
Lock in that Wednesday morning. It’s the only one.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for ADs/Doubles 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.
