The Lowdown

Alright, let’s get into it. The next 16 days are going to be a waiting game for us. We’ve got a whole lot of nothing to start, with tiny, weak swell and only a brief window of decent waves right at the end of the first week. After that, it’s flat again for a long stretch before things finally start to look interesting in the second week. Here’s the rundown.

The only real window for a session that’s worth getting excited about kicks off on Sunday the 2nd of August. Little Austi and Main Beach (Little-Austi-and-Main-Beach) will have a solid pulse of groundswell. The water temp is sitting at 64°, which is about average for this time of year. We’ll see a morning bump of 6 ft SSE swell with a very long period of 13 seconds, and the combined energy is solid at (910). That’s a proper groundswell with a lot of grunt, so it’ll be better out at the reef sections than the beach, and those long period sets mean you’ll have gaps between the big ones to get back out. The wind is from the NNW at 9 mph, which is a nice cross-off breeze, so the surface will be clean. That Sunday morning is the standout of the whole forecast. It’s a touch big for beginners but an intermediate will have a lot of fun. By the afternoon the wind swings NE and picks up to 12 mph, putting a cross-chop on it, so get out early.

Monday morning, the 3rd, still has some clean conditions with an offshore wind from the NW at 9 mph, but the swell has dropped significantly to just 3 ft SE. The energy is down to (193), and it’s just ordinary. It’s surfable, but it’s the kind of day you go for a cruise, not a thrill. The afternoon is similar.

Then from Tuesday the 4th through to Friday the 7th of August, it’s pretty much dead. Swell heights barely hit 1.0 ft, combined energy is all under 40, and it’s not worth paddling for. The morning of the 7th is glassy but there’s simply no swell. That’s a gap of nearly four days with nothing.

Saturday the 8th of August sees a tiny pulse of 3 ft SSE swell, period a short 9 seconds, and combined energy of just (98). The morning is clean with a light NNE breeze, but it’s uninspiring. Sunday the 9th is also small and ordinary. Monday the 10th has a bit more energy at (150) but it’s messy and windy from the W at 16 mph, so it’s a washout.

After that, from Tuesday the 11th through to Friday the 14th of August, it’s back to tiny, weak swell. Most days are under 1 ft, and the combined energy stays below 60. A couple of mornings are glassy or offshore, but there’s nothing to ride. Another 3-4 day gap of flatness.

Then everything changes. On Saturday the 15th of August, the afternoon looks insane on paper, but with a big caveat. The combined energy rockets to (2699) and there’s a 10 ft SSE swell with a 12-second period. That’s massive, expert-only territory. The wind is a light SE 3 mph, which is onshore, so it could be a real foamy, blown-out mess despite the size. The included data flags it as questionable and it’s not worth the risk unless you are a seasoned charger.

Sunday the 16th of August morning looks much better. The swell drops to 7 ft from the SSE with an 11-second period and combined energy of (1041). That’s still big and powerful, and the wind is from the WSW at 9 mph – a clean cross-off. This is the second standout of the entire outlook, but it’s only for experts.

Monday the 17th of August morning is a last little hurrah, with a clean 3 ft SSE swell but only (256) in energy. It’ll be clean with a N wind at 6 mph, but it’s just a nice little leftover.

Overall, don’t waste your time chasing waves until Sunday the 2nd of August for the morning session. That’s your one real quality window. The rest is a long, flat slog with a couple of very big days right at the very end that are serious business for experienced surfers only. Forecasts a week and a half out can change though, so keep an eye on it.
