The Lowdown
Alright, Rusty here, and let's talk surf. We've got one spot on the radar, and it's a very specific kind of wave. This is an advanced-level reef break that needs the right conditions to really fire, and honestly, for most of this 16-day stretch, the conditions are going to be a mixed bag.
The water temp is sitting at a balmy 80°F, which is pretty much bang on average for this time of year, so no surprises there in terms of needing a thick wetsuit or anything.
We kick off Monday, the 7th of September, with some solid swell – waves around 7 ft from the SSW, but the wind is a cross-onshore breeze at 12 mph, making it choppy and messy. It's a pass. Tuesday the 8th sees a change, with the swell dropping a touch to 5 ft in the morning, but the period jumps to a very long 19 seconds. That's a proper groundswell. The wave energy is massive, but the wind is still cross-shore, and with that long period, a beach break like this one can get a bit weird. It's better for a point or reef setup, but this is a reef break so it might line up okay. Still, the conditions are "marginal" so I'm not getting too excited.
The biggest issue throughout the whole period is the wind. It's almost constantly a cross-onshore or moderate breeze, keeping things choppy. The swell sticks around, but the quality just isn't there. There is a standout moment, but it's a long way off. On Monday the 22nd of September, Tuesday morning, we see a drop in swell height to just 4 ft, but the period is a stunning 20 seconds, and the wind is just a light breeze at 6 mph. For a short window, you might get some long, lined-up, clean waves at this reef. That’s the one to keep an eye on if you can wait.
The rest of the week after that is a repeat of cross-onshore winds and moderate swell, nothing clean enough to call a ripper session. The swell doesn't get big enough to be just for experts (it stays under 8 ft), so it's paddlable, but the onshore chop will ruin it.
For now, the setup is more interesting for a kite surfer than a dedicated paddle surfer, as most of the period is choppy and decently windy. The best bet is banking on that 22nd of September morning for a rare, clean, long-period swell.
Rusty out.
