Table - best surf conditions forecast for Little Austi and Main Beach over the next 16 days.
Alright, Rusty here. Let's break down what's happening at this spot.
The next few days are a bit of a bust, to be honest. From Wednesday through Friday, the wind is mostly sideways or blowing onshore, kicking up chop and making things messy. There's some size – up to 8ft on Wednesday morning – but the quality is no good. The wave energy is strong (1713), but you're fighting the conditions more than riding them. I'd give it a miss.
There's a lull after that. Saturday the 11th is the first day that looks half decent. Little Austi and Main Beach will clean up nicely with a light offshore NW breeze in the morning. Swell drops right back to about 2ft from the ESE, with a nice 12-second period – proper groundswell, long lines. The energy is moderate (299). It's clean, small, and better for a longboard or a funboard. Sunday the 12th through to Wednesday the 16th is basically flat or close to it, with some days showing zero wave energy. Don't bother.
Now, look ahead to Sunday the 19th. This is the one to circle. After that dry spell, we get a proper clean-up. The morning has 5ft of ESE swell with clean conditions and a light cross-off W breeze. The afternoon is even better: 6ft from the SSE, light wind, and it scores as "very good." The energy is moderate (680), but the combo of size and clean faces makes this the best session of the entire outlook for a fun surfer.
But Monday the 20th morning is for the experienced crew. You've got 8ft of ESE swell with an 11-second period, combined with a light offshore NW wind. The energy is strong (1372). This is excellent, powerful surf, but it's for experts only. The long period groundswell might make it a bit straight on the beach, but that offshore wind will hold it up nicely.
The water temp is about 65° right now, which is normal for this time of year.
To sum it up: the first week is mostly a washout. Saturday the 11th offers a small, clean session for the patient. The real highlights are Sunday the 19th afternoon – your best bet for clean, fun-sized waves – and Monday the 20th morning for the brave ones who want to handle some size and power.
Rusty.
