The Lowdown
Right on, same story but in old-school numbers. I'm Rusty, and here’s how it’s lining up for Akabane Long Beach in feet and miles per hour.
Start of the run, Tuesday the 25th of August: there's proper lift in the water. We’re talking a 7ft swell from the SSE, 13 seconds apart. That's a strong pulse (2422 combined energy). The miss is that it’s cross-onshore blowing at 9 mph, so the ocean’s a bit of a chop bucket. Lot of power but ugly.
Wednesday the 26th pulls the same trick, one foot smaller, but the onshore wind holds in there at 16 mph in the afternoon. Just not clean enough.
Thursday the 27th dies out quick. Drop to 3ft and messy.
Then Friday the 28th comes in as the absolute standout. 3ft of swell from the south, but this time an offshore wind from the Northwest at 9 mph. Clean faces, tidy lines, moderate energy (255) – it’s actually rideable and fun. That’s the morning to be in the water.
From the 29th onward into early September, surf flattens right out. Like 1ft to 2ft of weak crumble, often onshore or cross-shore. There’s a stretch that’s almost not surfable. Monday the 31st has a brief window of glassy, flat conditions (1ft, SSE) but it's basically a lake. By the 1st of September a pulse to about 4ft comes through, but the wind remains all wrong.
Then the 5th and 6th of September see a new pulse, up around 8ft from the East-Southeast. But it’s wind swell – period only 7 seconds and wind howling onshore at 25 mph. For a beach break like this, that’s just a washing machine. Any kayaker would love it; for the surfer, it’s not worth paddling out. Over 2.5m (8ft), that’s expert territory only anyway, and with these conditions, it tempts only kites.
The call for the whole window: Friday 28th August morning. Offshore breeze, 3ft of southern groundswell, proper period. That’s the day.
Water temp sits at about 83°F and right on average.
Rusty out.
