The Lowdown

G'day, it's Rusty here with a look at what's coming up for Akabane Long Beach.

The next week and a half is a bit of a mixed bag for this spot. We've got a bit of a slow start, but then a few windows of clean surf start to appear, especially for the early birds. The water is sitting at a warm 81°F, which is just a touch under the long-term average for this time of year, so it feels pretty normal.

The first real chance for a wave comes on Friday the 21st. The morning is looking glassy with a light SSW wind, and there's a 3ft swell from the south with a period of 10 seconds. The combined swell energy is a moderate 354, so there's a bit of push behind it. The swell direction is a good match for this break, which is set up for a SSE direction. It's a very consistent spot, so you'd expect some waves. The onshore wind builds in the afternoon and messes things up, so it's a dawn patrol mission.

The next standout is Monday the 24th. The morning is clean with a cross-offshore NW wind at 6 mph. The swell picks up to 6ft from the SW, but the period is a short 7 seconds, so it'll be a bit bumpy and less powerful. The energy is moderate (598), but that short period can make for a bit of a lumpy surface. The afternoon also stays clean but the swell drops off.

Then, Tuesday the 25th morning is the pick of the early window. The wind is offshore from the NW at 9 mph, and we've got a 4ft swell from the SE with a very long 14-second period. The energy is a strong 540. That long period groundswell will produce some nice, well-shaped lines, particularly at a beach break like this, though it might make the sets a bit inconsistent. The water is clean.

The end of the forecast period sees a massive increase in swell. From Thursday 27th August, the swell is predicted to be over 10ft, and by Friday 28th it's up to 13ft from the SSE. The energy numbers are huge—over 7500 in some cases. The wind is offshore for the mornings, but the swell is too big for this break, even for experienced surfers. It's a case of being too much of a good thing. The 31st of August morning has a glassy 7ft south swell, which is excellent for experienced surfers, but the energy is still a very strong 1786. The crowds can be often here, so keep that in mind.

So, to sum it up: the best windows are the mornings of the 21st, 24th, and especially the 25th of August. The later stuff is just too big for this long beach.

Rusty out.
