The Lowdown
Alright folks, Rusty here. Let’s be straight with you about the next 16 days for Triggs Beach. Look, the data's all pointing to a pretty brutal run of tiny, weak surf. The combined swell energy is mostly in the teens or single digits, which is basically flat. We’re looking at a long stretch of poor surf conditions with hardly anything to get excited about.
We kick off Friday the 21st with a tiny 0.3ft southwest swell at a 14-second period – that's a long period for a wave that small, and with the wind blowing onshore from the WSW at 6 mph, it’s just not gonna be worth paddling out. The water’s sitting at 57°, which is about average for the year, so nothing unusual there.
The whole run from the 21st right through to the end of the first week is dominated by these 0.3ft to 1ft swells, if you can even call them swells. Wind is all over the shop – onshore, cross, cross-off – but it doesn't matter much when the wave heights are that low. Saturday morning, the 22nd, has a glassy moment with a 0.3ft surf and a slight air, but it’s still just flat. The combined energy never gets above 13, and at times it drops to zero. We’ve got days with no swell at all, like Sunday the 23rd morning and Wednesday the 26th afternoon.
Heading into the second week, it’s more of the same. Monday the 31st through to Wednesday the 2nd of September shows a few 0.3ft to 1ft bumps, but the combined energy is still pathetic – 4 on the 31st, 3 on the 2nd of September. The swell direction shifts around from S to N, but with periods mostly under 10 seconds, it's weak and short. Wind is still a factor, with some clean cross-off conditions on the 31st morning, but again, no power behind it.
The last few days, the 3rd through the 5th of September, see a bit more wind – 19 to 22 mph from the north and west – but the wave heights barely register. The 4th of September morning has a 0.3ft southwest swell with a 13-second period, but the onshore wind is a fresh 22 mph, making it a total write-off for surfing.
Honestly, there’s not a single standout session in this entire 16-day window. The biggest wave we see is 1ft, and that’s hardly a wave. If you’re a beginner, there’s nothing to learn on, and for anyone else, it’s just flat. The spot is sheltered and inconsistent, so this kind of blank run is more normal for the area. Don’t hold your breath. Forecasts can change, but right now, it’s a long, flat spell.
Rusty.
