The Lowdown
Hey, Rusty here. Let’s talk surf for the next couple of weeks. It starts quiet but there’s a couple of windows worth paddling for.
Sunday the 23rd is a total dud – tiny, weak waves and poor conditions. Skip it. The first real chance comes Monday morning the 24th at Akabane Long Beach. Light cross-offshore breeze, clean lines, and the swell is coming from the SSE at about 3ft with a long 18-second period – that’s proper groundswell with good energy behind it (combined energy 948). Water temp is about 81°F, pretty normal for this time of year. This is the standout early, but don’t sleep in – the afternoon gets choppy with cross-onshore wind.
Tuesday the 25th sees bigger swell around 6-7ft from the SSE, but the wind is cross-shore and the quality is only marginal. Wednesday and Thursday mornings have similar size but with cross-onshore or glassy conditions. Thursday morning the 27th is worth an early alarm – glassy conditions, 5ft from the S, 11-second period, and clean waves.
From Friday the 28th through the end of August, it’s mostly poor with small swell and messy winds. A few days of nothing worthwhile.
Come September 1st, the swell builds again but so does the wind – strong cross-onshore and completely blown out. By the 4th and 5th, we’re looking at 8-13ft swell with gale-force winds. That’s expert-only and honestly, it’s more of a kiteboarding show than a surf session. Combined energy hits over 7000 on the 5th, but the conditions are shocking.
The real gem is Sunday the 6th of September. Morning has glassy conditions with a light offshore breeze from the NNW at just 6 mph. Swell is a clean 5ft from the S, 11-second period. Combined energy is 652, moderate but with that offshore wind, the waves will be peeling nicely. Afternoon stays clean with a moderate offshore breeze. This is the best session of the whole 16-day run. It’s a week and a half away, so keep checking in, but this one has real promise.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Akabane Long Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
