The Lowdown
Alright, let’s look at what’s on offer across the next two weeks for Akabane Long Beach.
It’s a slow start. On Monday the 14th and Tuesday the 15th of September, the swell is small and weak – around 3 to 4 feet of short-period SE energy, with light cross-onshore winds putting a chop on it. Nothing to get excited about.
Wednesday the 16th and Thursday the 17th stay pretty flat – waves between 3 and 5 feet, but the wind switches around and the quality is poor. Wednesday morning cleans up slightly with a light cross-offshore from the NE, bumping a 3-foot SE swell, period around 8 seconds. Energy is low, so it’s more of a gentle paddle than a real surf session.
Then Friday the 18th morning, things start to look up. The swell builds to 6 feet from the east, period 8 seconds, combined energy hits a moderate 791, and the wind is nearly nothing – just a slight breeze from the ENE. It’s not tidy enough for a recommendation, but it’s getting warmer.
Here comes the big highlight: Saturday morning, September 19th. The surf pumps up to 10 feet from the SE with a long 14-second period (groundswell). Wind is light from the NNE and cross-offshore – that’s clean. Combined energy is a whopping 4295 – that’s very strong, powerful surf. This is expert territory, not for beginners. For a beach break, that long-period groundswell will throw up some fast, hollow lines, but also means long waits between sets. Crowds are often here. If you’re skilled and hungry, this is it.
Sunday the 20th holds similar size – 10 feet from the SSE, period 13 seconds, combined energy 4206, and light cross-offshore north wind again delivering clean conditions. Another serious day for the crew with experience.
After that, from Monday the 21st to Tuesday the 22nd, the swell gets huge – 11 to over 21 feet – but the wind turns hard onshore, blowing 18 to 43 mph, turning the ocean into a washing machine. Combined energy rockets up to over 20,000, but it’s completely blown out. This is kite-surfing territory, not paddle surfing.
From Wednesday the 23rd through to the end of the month, conditions stabilize into small, clean surf. Saturday the 26th morning: 3 feet from the SE, 9-second period, glassy offshore from the NNW, combined energy 159 (weak). Sunday the 27th morning: 2 feet SE, 9 seconds, clean offshore from the NW at 9 mph. By Tuesday the 29th, you have a 6-foot ESE swell, period 11 seconds, combined energy 816 (moderate), but the wind is light cross-shore and it’s described as marginal.
So the prime window? Saturday the 19th morning – that’s the true standout. Big, clean, powerful groundswell for experts only.
