The Lowdown
Alright, Rusty here. Let’s break down what’s happening in our local waters over the next couple of weeks.
To be honest, it’s a bleak picture. The first real chance for a wave doesn’t show up until the middle of next week, and even then, it’s not looking pretty. There’s a long stretch of nothing but tiny, wind-affected surf.
The only break in the game is The Breakwater-St Ives, a point that’s inconsistent at the best of times. The water temp is about 65°, which is a touch warmer than normal for the season.
We’re looking at a big dry gap until Wednesday, August 12th. That morning brings a 3ft swell from the West, with a 10-second period and moderate energy (198). The catch? The wind is cross-onshore from the ENE, making it pretty choppy. No standout there.
Thursday, August 13th, has a bit more size – 4ft from the West, period hitting 11 seconds, and energy up to 322 (moderate-strong). But the wind is onshore from the NNW in the morning and cross-onshore from the NW in the afternoon. It’s going to be lumpy and messy.
Friday, August 14th, offers the best of a bad situation. The swell drops to 3ft from the West, but the wind goes cross-shore from the W in the morning – the cleanest wind we’ll see all forecast. Period is 9 seconds, energy is 126 (moderate). It’s not firing, but with the wind siding up, you might find a couple of rideable ones. Still, “poor surf conditions” is the official word.
The rest of the outlook into the third week of August is just onshore wind and building, messy swell. We see waves hitting 6ft on Wednesday the 19th, and even 5ft on Thursday the 20th with strong energy (520), but it’s all blown out by onshore winds. For a point break that needs clean conditions, that’s just junk.
If you’re really jonesing, Friday the 14th of August morning is the pick. It’s not a standout, just the least ugly wave in the lineup. For everything else, the wind is just too mean. This spot is inconsistent, and this run of poor forecasts is exactly why.
Rusty.
