The Lowdown
Alright, let’s get into it.
The next couple of days are a bit of a write-off, but don't hang up the wetsuit just yet. There’s a decent pulse of energy lining up through the middle of next week, and if the stars align, we could see some proper sessions. The water’s sitting at a touch warmer than usual for this time of year, which is a bonus.
Right now, we’re looking at clean but weak surf. Wednesday morning has a bit of cross-off breeze and a 5ft NW swell, but the period’s short and the energy’s weak, so it’s not going to be doing much. By the afternoon, it turns a bit messy. Thursday and Friday bring some glassy mornings, but the swell’s inconsistent and lumpy at times. Friday afternoon does pick up though, with a 6ft+ NW swell and a longer 13-second period, and the energy’s building. It’s still a bit raw, but there are waves to be had.
The real standout comes early next week. Saturday morning the 19th is looking prime—6ft+ of NW swell, glassy conditions, and the energy’s cranking (1204). That’s the one to circle. It’s pushing towards the top end of the range, but it’s clean and powerful, perfect for anyone with a bit of experience. Sunday and Monday mornings are also clean and still have some decent 5-6ft NW swell, but they’re not quite as strong.
Then we hit a bit of a dry patch. Tuesday and Wednesday drop right off, with smaller swell and onshore winds messing things up. It’s lean.
But hold on, the real beast is lurking. Wednesday the 30th is showing a big 10ft+ WNW swell, but that’s just too much for this break. The energy’s huge (1484), and it’s going to be shutting the place down. Not one for the average punter. The next day, Thursday the 1st of October, it backs off to a still-solid 8ft WNW, and with a clean cross-off breeze in the morning, it could be firing for the experts. That’s a proper strike mission if you’ve got the skills.
So, to sum it up: the best window is Saturday the 19th, with that glassy 6ft+ NW swell. The long-range stuff at the end of the month is promising but way less certain, and it’s a lot bigger, so only for the experienced crew. The gaps in between are pretty bleak, so pick your sessions wisely.
Rusty out.
