The Lowdown
Alright folks, it’s Rusty here, and honestly, it’s a bit of a slow start out there at Little Austi and Main Beach. We’ve got a long 16-day forecast window, but don’t expect much action for the first week. This patch is known for having quiet spells, and this is one of them. We’re looking at a gap of about 6 days before anything really starts to shape up, so patience is key.
The early days are a write-off. Thursday the 6th and Friday the 7th have tiny, weak swell with combined energy readings of just 21 to 71 – that’s weak energy, barely a ripple. Winds are a mix of cross-off and onshore, but the waves are just too small to bother with. Saturday the 8th is glassy in the morning, with a light breeze, but again, the swell is only 1 ft and the energy is a paltry 48. It’s flat, plain and simple.
Come Sunday the 9th, we finally see a little bump. The morning brings a 3 ft swell from the ENE, period around 9 seconds, and combined energy hits 150 (moderate). Winds are cross-off and clean, so it’s surfable, but ordinary. The afternoon sees a bit more energy (187) but with light rain and a stronger cross-off breeze. It’s still not worth rushing out for.
Monday the 10th is a bit of a tease. The morning jump to 7 ft from the NE with a fresh cross-off breeze and combined energy of 719 (strong wave energy) sounds big, but the forecast calls it marginal due to questionable tide conditions. The wind is strong at 35 km/h, which will be messy. This one is for the experienced crew only, if anyone bothers. After that, Tuesday through to Friday the 14th drops back into the doldrums with tiny surf and poor conditions.
Now, this is where it gets interesting. The real standout kicks off on Sunday the 16th of August. The morning shows a 8 ft swell from the east at 11 seconds, with a combined energy of 2108 – that’s very strong wave energy. The wind is light cross-on, but the afternoon is the true gem. We’re looking at 8 ft from the east, a 12-second period, and the wind goes glassy. The energy is a massive 2457, and the conditions are described as excellent for experienced surfers. This is the one to circle on the calendar. The swell direction is a touch east of the optimum ENE, but with that size, period, and glassy conditions, it’s going to be a proper session for the advanced crew.
Monday the 17th keeps the size going with 10 ft in the morning and glassy conditions, but the wind switches onshore in the afternoon. The following days, Tuesday the 18th and Wednesday the 19th, still hold good size – 6 ft to 7 ft – with clean conditions and solid energy in the 700 to 900 range. The water temperature is about average for this time of year, so no surprises there.
The best of the best is absolutely the afternoon of Sunday the 16th and the morning of Monday the 17th. Big, powerful east swell, glassy winds, and very strong energy. This is not for beginners – anything over 8 ft is expert territory. If you’re in the game, get ready.
Stay patient, stay stoked.
Rusty.
