The Lowdown
Alright folks, let’s get into it. This is Rusty, and I’ve been staring at the charts for Oswald State Park/Short Sands, and honestly, it’s a long and pretty grim stretch ahead. The whole 16-day window is a real struggle.
We’re starting on Monday afternoon, the 17th of August, and the water is *much colder than normal* for this time of year, with temps down at 54°. That’s a serious anomaly, over three degrees cooler than usual, so you’ll be wanting a thick suit.
The first few days are a write-off. Monday afternoon has a tiny 2ft southwest swell but it’s wrapping in under a cross-onshore breeze, making it choppy and poor. The combined energy is weak (165). Tuesday and Wednesday are just more of the same low-energy, messy slop. We're talking poor surf conditions right through.
Things tease us a little on Wednesday afternoon, the 19th, when the swell bumps up to just over 4ft from the WNW. The combined energy is moderate (572), but it’s still cross-on with a gentle breeze, making it fairly choppy. The ride is marred by marginal conditions. Not the day to cancel plans for.
The entire second week stays pretty bleak. The swell drops off again, and we get a lot of strong cross-shore winds, some hitting 18 mph, which just chops everything up. On Thursday morning, the 27th of August, there’s a brief moment of glassy conditions with a tiny 1ft south-west groundswell (222 energy), but it’s so small it’s hardly worth a paddle. The rest of the week is back to onshore slop.
There is no true standout here. The best you can hope for is that Thursday morning (27th) glass-off, but the swell is pathetic. For the rest of the forecast, with the onshore winds and poor quality, this setup looks more interesting for kite surfing than paddle surfing. It’s a long, flat, and choppy run. Hang in there, the forecasts can change, but for now, it’s a bust.
