The Lowdown
Alright, let’s get into it. The Slot’s been pretty quiet to kick things off, but there are a couple of windows that’ll get the blood pumping.
The next week and a bit is mostly about small, clean surf. Friday the 14th and Saturday the 15th are super marginal – you’re looking at knee-to-waist high dribble with an onshore breeze messing it up. Not worth paddling out for unless you’re desperate. Sunday and Monday stay small, and the wind is just a little cross-on, so it’s not going to be pretty.
The first real glimmer of hope comes Tuesday morning the 18th. The swell’s still small, but the wind goes glassy, and that’s when this place can feel like a different world. The energy is weak, around 660, but the surface will be clean. It’s still small, but you could get a few fun ones if you’re in the right spot.
Then things get a bit more interesting around Wednesday the 19th and into the following weekend. The swell picks up a little, but the period drops off to that short-period, windswell stuff, coming from the NW. It’s a bit more push, but it’s not the clean, lined-up groundswell we love. It’ll be bumpy and a bit all over the place. The morning of the 22nd and the 24th will see some waist-chest high waves, but that short period makes it a bit crumbly.
Now, for the standout. Mark your calendar for Friday the 28th of August. The energy jumps way up to 1237, and we’ve got a solid S swell mixing in with a 15-second period. It’s still not huge, but it’s got some push – think head-high plus on the sets. The wind is light and cross-off in the morning, which should keep it pretty clean. This is the best-looking window in the whole 16-day stretch. This reef can handle that S direction really well, and with that long period, it should be holding some proper shape. It’s a bit of a wait, and the long-range forecast is always a bit less certain, but this one has all the signs of being the pick of the month.
There’s a smaller bump on the 29th with a similar S swell, but the energy is lower, and it’s already fading.
One thing to keep in mind: this break is a reef setup that sees its fair share of crowds, and it’s consistent. So when the bigger S swell hits on the 28th, expect it to be busy, but for good reason.
The water temp is about average for this time of year, nothing crazy.
It’s going to be a week of small waves and waiting, but that Friday the 28th surf is worth the patience. Get it while it’s there.
