The Lowdown
Alright folks, Rusty here. Gotta be straight with you – it's a bit of a slow start out there at Oswald State Park/Short Sands. We're looking at a long, quiet stretch to kick things off, so don't bother paddling out just yet.
From Sunday the 9th right through to Thursday the 13th, it's a write-off. The wind is messy, mainly cross or cross-onshore, and those weak little NW swells are only pushing around 1 to 5ft. The wave energy is weak to moderate (106 to 316) but it's all wind chop and poor conditions. Not worth the wetsuit peel. Friday the 14th and Saturday the 15th don't look much better – the wind swings onshore and the surf stays small and weak.
In fact, the first real glimmer of hope doesn't swing into view until Tuesday the 18th. That morning, we finally get a break in the weather. It's glassy – actually glassy – with a light offshore touch from the ESE. That moderate SW groundswell at 3ft with a long 14-second period will have some shape, but at a beach break like this, long-period swells can get a bit straight. Still, for the first proper surf in over a week, you'll take it. The combined energy jumps right up to 460, showing there's some real power behind it.
There's another little window on Wednesday the 19th afternoon. The wind goes light cross-offshore, cleaning up a 3ft W swell with an 11-second period. That combination of clean conditions and a bit more size makes this the standout of the whole outlook. It's not huge, but it'll be the best shaped and most fun you'll find.
After that, the surf drops away again. The rest of the week looks pretty average with onshore winds and small chop, and the final days are a mess of rainy conditions and weak, choppy surf right through to Monday the 24th.
So to sum it up: tough sledding for the first week and a half, but Tuesday the 18th morning and Wednesday the 19th afternoon offer some clean, rideable waves. The water temp anomaly isn't given, but the ocean feels about what you'd expect for this time of year. Hold tight and wait for that glassy spell.
Rusty.
