The Lowdown
Second Text (Imperial Units)
Alright, let’s break this down. We’re looking at a real quiet stretch here at Oswald State Park/Short Sands. The first surf that’s even worth a look doesn’t come around until Thursday, August 14th. Before that, it’s a whole lot of nothing – messy, cross-shore winds from the north and northwest just killing any chance of a decent wave.
The one to circle is the morning of Thursday, August 14th. We’ll see a 5ft swell from the northwest, with a period of 8 seconds. The combined energy is a moderate 520. The wind is a light breeze from the northwest, so it’s cross-onshore, but it’s light enough that it won’t totally trash the surface. It’s still a marginal call, but it’s the best option on the board. The swell size is okay for most, but that cross-onshore wind will keep it from being glassy. The Friday morning on the 15th has a bit of swell but the wind turns onshore from the west-southwest, so that Thursday morning is your best bet.
After that, the weekend just fades back into weak, small swell and more wind. The water temp is about what you’d expect for this time of year.
It’s a tough outlook, but that’s the way it goes sometimes. Keep an eye on the charts, because a change can come quick. Thursday morning is your window.
