The Lowdown
Alright folks, Rusty here with the long-range look. This time in feet and miles for ya.
First off, we're looking at a pretty bleak start across the whole 16-day window here. The only spot on the radar is Little Austi and Main Beach, and for the first week or so, it's a total write-off. We've got a solid 9 days of flat, weak, or messy conditions from Tuesday the 15th right through to Wednesday the 23rd. Don't bother paddling out for that; it's a proper gap.
The first real glimmer of hope doesn't show until Thursday the 24th. That morning, we've got a 5ft swell pushing in from the NE, and with a gentle NNE cross-offshore breeze, it should be clean. The energy is moderate, and the period is a short 6 seconds, so it'll be a bit weak and sectiony, but it's the best we've seen. This spot is an exposed beach and reef, so it picks up everything, but that short period means it'll be fat and soft. Expect it to be a bit of a grovel, and with the crowds being 'sometimes' an issue, you might have some company. Thursday afternoon gets a bit choppier as the wind picks up to a moderate cross-shore, so the morning is definitely the move.
Then we roll into Sunday the 27th, and this is the standout of the whole outlook. The morning brings a solid 6ft SE swell with a gentle N cross-offshore breeze keeping it clean. The energy is moderate. The swell direction is from the SE, which isn't the optimum ENE direction for this break, so it might be a little awkward, but the size and clean conditions make it the best on offer. It's not huge, but it's rideable for intermediates. The afternoon holds clean too, but the wind gets a bit stronger. That Sunday morning is the one to circle on the calendar.
Monday the 28th afternoon also looks promising, with offshore WNW winds and a 3ft ENE swell, giving us clean conditions. It's smaller, but offshore wind is gold, and that'll make for some fun, lined-up waves, especially with the period stretching out to a slightly better 9 seconds.
Overall, it's a slow couple of weeks with a few bright spots. Thursday the 24th morning and Sunday the 27th morning are your best bets. The rest of it is mostly choppy, onshore, or just flat. Don't get your hopes up for anything before that.
Rusty.
