The Lowdown
Alright, folks, let's cut the crap. The next two weeks are looking like a desert for surf. We've got a long stretch of junk ahead, so don't get your hopes up for any real rides.
The first time we see even a hint of a wave is over a week away, around the 25th and 26th. But even that's not good. We're talking small, weak, short-period windswell, with a nasty cross-onshore wind that's going to mess it all up. It looks more like a kiteboarding day than a surfing one.
Water temp is a warm 86°, about average for this time of year, so you won't be cold, just bored.
Here’s the rundown.
The First Week (Aug 15-22): This is a total washout. Swell heights are barely a ripple, from 0.3ft to maybe 1ft. The energy is pathetic, with readings in the low single digits to the 20s (like 10, 19, 28), just nothing behind it. Winds will be light and variable, with a few clean windows, but it's all for nothing with zero swell. Those glassy mornings on the 16th and 22nd will just be flat, shiny water. Nothing to surf.
The Middle Week (Aug 23-24): Still flat. Swell remains tiny at 0.7ft, and the east wind starts to pick up, making things choppy. Energy stays in the low teens. Same story – leave the board at home.
The Second Week – A Flicker of Hope? (Aug 25 on): About a week out, we might see things get slightly less terrible. On the 25th and 26th, the swell might push up to a whopping 2ft, but the period is a weak 4-5 seconds. This is just messy, short-period wind-chop. The energy numbers tick up a bit, and on the 26th afternoon, we see an 84 as the period jumps to 15 seconds. That long period is interesting, but it's from the east and hitting a spot exposed to the NE, so it's not great.
The wind stays as an east cross-onshore, so it'll be lumpy and rough. The 27th has a better period, but still small height. This could mean some long-period energy is trying to show, but it'll likely be closing out at a beach and reef break like Walton Rocks (Power Plant). Not the makings of a clean, rideable wave.
The Bottom Line: There’s no standout session in this whole 16-day window. The only thing worth mentioning is around the 25th and 26th, and even that is junk. This is a long, flat spell. The data shows the spot is very consistent, so it usually doesn't stay this bad for long, but this forecast window is a tough one. Keep your boards in the rafters and wait for the next storm.
