The Lowdown
Alright, let me break this down for you straight.
The next couple of weeks are looking pretty bleak for a proper surf. There’s a lot of junk energy and onshore wind filling in the forecast. It’s one of those stretches where you’ll be checking the cam and then walking right back inside. We have a small window of cleaner conditions but the swell just isn’t there to get excited about. Hang tight, because it’s not a total washout, but you’ll need to pick your moments.
We’re starting off this stretch with nothing but closeouts and chop. Wednesday morning kicks things off with a tiny 1ft of windswell coming from the E at a short 5 seconds. It’s cross-on and messy, and honestly, not worth getting wet. That afternoon the breeze picks up, making it even worse. Thursday stays in the same boat, with 1ft and a cross-shore wind. We see a slight glimmer of cleaner skies on Friday morning with a cross-off breeze, but the swell has dropped to a pathetic 0.7ft. That’s a board-waxing and lawn-chair day, not a paddle-out session.
The weekend turns ugly. Saturday sees the swell bump up a bit to 3ft, but it’s onshore and junky. Sunday is a mess with a cross-shore wind and lumpy, sectiony waves around the 3ft mark. Early next week, Monday brings a fresh cross-onshore breeze and building, raw swell. The size jumps up Tuesday, with 6ft on the morning session, but it’s straight onshore and stormy. Not a single wave out there is going to be worth the fight.
Now, here’s where things get interesting. On Wednesday the 23rd, we finally catch a break. The morning is glassy with a clean 4ft of E swell. The wind is dead calm. It’s surfable for sure, but the conditions are still pretty ordinary – no punch, no shape. The period is only 7 seconds, so it’s all a bit soft and mushy. Still, if you’re desperate, this is the best looking, cleanest paddle of the last week.
After that, the swell drops right back out. Thursday and Friday mornings see some cleaner conditions, with a fresh offshore breeze on the 25th, but there’s barely any swell. We’re talking 1ft at best. That’s not surf, that’s just ripples. The rest of that week stays tiny.
Then, at the very tail end of the window, there’s something on the horizon. On Wednesday the 30th, we see a pulse of new energy. The morning has a clean 4ft from the ESE, and the wind is light offshore. It’s surfable, but still pretty average. The afternoon, though, shows a jump to 7ft. The energy really ramps up, with a combined swell energy of 384. That’s a solid amount of push. But the wind goes cross, and the period is still a short 7 seconds, so it’s going to be lumpy and sectiony. It’s a tease.
Then it really kicks in. Thursday the 1st of October is the standout, if you can call it that for this stretch. The morning brings a 8ft swell from the ESE at 11 seconds. That’s proper groundswell energy, and the combined energy is a massive 1221. That’s a serious amount of water moving. But the wind is fresh cross-onshore and it’s choppy. The afternoon sees the size drop slightly to 7ft, but the energy is even higher at 1618. This is powerful, but messy. You’ll need to be an experienced surfer to handle this kind of raw, unruly power. This is definitely expert territory only.
Honestly, for this spot, the whole window is a struggle. The water temp is a notable 75°, which is a good 4° warmer than usual for this time of year, so you won’t need a thick wetsuit. But that doesn’t help the waves. The only real standout is that Thursday the 1st, with that big, long-period groundswell. It’s promised, but with that onshore wind, it’s a gamble. For the intermediate surfer, that Wednesday the 30th might be the best bet for a clean-ish wave, but it’s small. For everyone else, this is a time to find other things to do.
Signing off, Rusty.
