The Lowdown

Alright, Rusty here, and I gotta be straight with you — this forecast is a rough one. We’ve got a single spot on the radar, Udo Shrine, and honestly, it’s a no-go for the vast majority of the next 16 days.

The outlook starts with a bang, but not the good kind. From Thursday, August 6th, right through the first week, we’re staring down the barrel of some serious, dangerous swell. Thursday morning kicks off with a massive 20 ft swell from the ESE, with a very long period of 15 seconds. That’s genuine groundswell, but the wave energy is absolutely insane at 16632 — that’s very strong energy. The problem is, it’s just too big. This is expert-only territory, and even then, the wind is a screaming 31 mph from the NE, making it a near gale cross-onshore. It’s blown out and dangerous. That afternoon, it actually gets worse, with a 23 ft swell and energy jumping to 44365. The wind stays onshore and brutal. Friday and Saturday are much the same story — solid, powerful swell but with strong onshore or cross-onshore winds, creating nothing but poor, lumpy conditions. Water temp is a warm 85°, which is about 1° above normal, so nothing unusual there, just a normal tropical bath.

We get a bit of a lull from Sunday, August 9th, through to the end of the first week, but the swell drops and the wind, while easing a little, stays cross-onshore. The wave energy drops to moderate levels (around 2000-3000), but the quality is still poor. There’s a brief window on Tuesday, August 11th, where the wind drops to a gentle breeze and the swell sits around 5 ft to 6 ft, but it’s still cross-onshore and the comments say marginal at best. It’s not worth the paddle.

The second week, from around August 12th onward, is flat and lifeless. Swell heights drop below 3 ft for days, the wave energy is weak (under 500), and the occasional 5 ft bump on August 19th is still too small and weak to get excited about. The wind is light, which is a positive, but there’s just no power in the water.

The only possible standout — and I say this with a heavy heart — is the very end of the forecast. On Wednesday, August 19th, we see a small pulse of 5 ft to 5 ft swell from the E with a period of 10 seconds. The wave energy is still weak (520-575), but the wind is light and cross-onshore. It’s still marginal, but it’s the best we’ve got. For a reef break like Udo Shrine, a longer period is good, but this is a short period windswell, so it won’t have the same punch. The wind is light, so it’ll be cleaner than anything else in the window. But honestly, don’t get your hopes up.

Given the predominant onshore and cross-onshore winds and the significant swell early on, this setup is looking more interesting for kite surfing than paddle surfing for the first few days. The rest of the time, it’s a waiting game.

Rusty.
