The Lowdown
Alright, let’s talk surf, Rusty style. We’ve got a 16-day window, and the only spot on the radar is Manu Bay. It’s a slow start, but there’s a proper pulse of groundswell coming for the weekend of the 15th and 16th that’s going to be the highlight.
The first few days are small. Monday the 10th has a 0.8m to 1.1m WSW swell, but it’s crossed-up and the energy is only moderate (658 to 777). Not a total loss, but you’ll be hunting for a ride.
Tuesday the 11th is the gem of the early week. The morning is glassy with a 1.0m WSW groundswell at 14 seconds, and the energy is a moderate 478. It’s an easy paddle and the waves will be clean. Tuesday afternoon turns flat calm with a 0.9m, 13-second swell (468 energy). A great little window for some smooth ones.
Wednesday the 12th gets a bit bumpy with a 20 km/h cross-offshore breeze, and the swell drops to 0.7m. The energy dips (371), and the afternoon gets messy. Thursday the 13th is a no-go with a 0.9m, 10-second short-period swell from the WNW.
Friday the 14th afternoon is the build-up. The wind settles to a light 15 km/h cross-off, and the swell is 1.1m WSW at 16 seconds. The energy is a strong 728, and the reports are for very good surf. A solid warm-up.
Saturday the 15th is the absolute standout. The morning has a 1.5m W swell at a long 17 seconds, with a light offshore. The energy is 1435 (strong), and the conditions are clean. This is excellent for experienced surfers, and that long period is a dream for a point break like Manu Bay. The afternoon gets bigger, 2.1m WSW at 17 seconds, with a massive 2636 energy. It’s going to be pumping, but it’s expert-only territory.
Sunday the 16th morning sees the peak: 2.5m WSW at 16 seconds, 3256 energy. The wind is a bit cross-shore, so it’ll be lumpy, but the power is huge. Sunday afternoon is the big one: 3.0m WSW at 16 seconds, 3800 energy, and a clean cross-off breeze. This is heavy water, only for the well-prepared.
Monday the 17th and Tuesday the 18th see the swell back to 1.5m to 2.0m, but the wind is stronger on Monday (25 km/h), so keep that in mind.
From the 19th onward, it’s a more moderate run of 1.0m to 1.3m WSW groundswell. The 21st of August looks fun with a 1.2m, 16-second swell and light offshore winds.
The end of the forecast, around the 24th and 25th, is small but glassy. The 24th afternoon has a 0.7m swell with flat calm conditions, and the 25th morning offers a clean 0.9m with a light offshore. Worth a paddle for the quiet ones.
Rusty, out.
