The Lowdown
Alright, let me tell you how it’s looking. I’m gonna be straight with you – this stretch is a bit of a tough one. The surf’s pretty quiet for the next week or so, and honestly, it’s not looking great. There are a few days that might be worth keeping an eye on, but overall, you’re gonna have to be patient.
For the first few days, we’re seeing small, weak swells and a lot of cross and cross-onshore winds. The water temp is sitting around 58°, which is about normal for this time of year. The waves are tiny – like 1ft to 3ft – and the period is short, so the energy’s low (119 to 137). Not really worth paddling out unless you’re a beginner and just want to get wet.
We’ve got a long stretch of nothing special until around the 18th of August. That Tuesday afternoon looks like the first real chance for something clean. A 4ft swell from the west with a 9-second period, and the wind goes cross-off and light. The combined energy is 391 – moderate, but the clean conditions make it the standout. This is the one to aim for if you can.
Then the 19th and 20th see a little more size, with 5ft and 5ft from the west, but the wind is cross-on, so it’s not going to be perfect. The energy picks up (510 to 565), but it’s still marginal. The 20th has a light breeze, so it might be okay for a session.
The 23rd and 24th have some bigger swell – 6ft and 5ft from the west-northwest – but the wind stays cross-on or cross. The energy is strong (615 and 561), but the quality is still not there. For a bigger day, you’d want cleaner wind.
So, the best bet is Tuesday the 18th afternoon at Oswald State Park/Short Sands. That’s the one with the clean wind and decent waves. After that, it’s a waiting game.
Stay patient, keep checking the forecasts, and I’ll be here.
