The Lowdown
Alright, this is Rusty. Let’s have a look at what’s on offer.
Honestly, the next couple of weeks are a bit of a flat spell for this stretch. The first proper surf recommendation doesn’t kick off until Thursday the 13th of August, and even then it’s not much to write home about. We’ve got a gap of a couple of days with nothing worth paddling out for right at the start.
The best chance for a decent wave comes on Thursday the 20th of August at Oswald State Park/Short Sands. Early morning, there’s a touch of WSW wind, glassy-like, with a 3 ft swell from the W. The period is 12 seconds, so that’s a proper groundswell, giving the waves some shape and a bit of punch. The combined energy is moderate at 314. It’s a beginner-friendly break, so if you’re looking to get wet without getting hammered, this is your window. The water is running a bit colder than normal for this time of year, so you’ll want a good suit.
For the rest of the run, it’s a lot of small, weak, and messy. The wind is mostly cross or cross-onshore, keeping things choppy and uninviting. Swell sizes hover around 1 ft to 4 ft, but with short periods or just poor conditions, it’s a struggle to find a clean face. The other morning that might be worth a look is Friday the 14th, with a 3 ft swell from the WNW and light onshore wind, but it’s only a marginal, questionable tide situation. The energy is moderate at 211, but it’s not going to be a standout.
Later in the window, around Wednesday the 19th, the swell energy jumps up to 479 (strong) with 4 ft from the W and a 12-second period, but the wind is a moderate cross-onshore from the NNW, so it’s just going to be a choppy mess. Not worth the paddle unless you’re desperate.
Overall, the best bet is the morning of the 20th. It’s not a world-beater, but with the clean(ish) wind and a bit of groundswell, it’s the pick of a very quiet couple of weeks.
Rusty.
