The Lowdown
Alright, Rusty here. Let’s break down what’s coming for the surf.
The first few days are a bit slow, but we’ve got a couple of clean windows that are worth getting out for, especially early next week.
The 5th of September is a no-go. The water is a touch warmer than average at 71°, but the swell is a messy 5 ft from the NNW with a short 13-second period and a cross-on 30 km/h wind. The combined energy is moderate (798), but it’s lumpy and poor.
The first real chance is Sunday morning, the 6th. The swell is a clean 5 ft from the NNW with an 11-second period, and the wind is a light cross-off 15 km/h from the WSW. The energy is moderate (503) and the forecast says "clean." That’s a solid session.
Monday morning, the 7th, is still clean with a 3 ft NW swell, but it’s a bit ordinary. Tuesday morning, the 8th, is glassy with a 3 ft NW swell, but the energy is weak (141). You’ll be working for them.
The 9th of September brings a spike to 7 ft from the NW but with a short 7-second period and a fresh 30 km/h cross-shore wind. The energy is moderate (522), but it’s messy. That’s more for the kite crew.
The 10th of September is a good one. Thursday morning is clean with a 4 ft NNW swell, a 10-second period, and a light offshore breeze. The energy is moderate (365). Thursday afternoon is glassy with a 4 ft NW swell. That’s a clean, fun afternoon.
Friday the 11th is glassy in the morning with a 4 ft NW swell (259 energy). It’s surfable.
After that, the surf drops and the winds turn onshore. The standout in the second week is Wednesday morning, 16th September. It’s glassy, with a 5 ft NW swell and a long 12-second period. The combined energy is strong (532) and the forecast says "expect good surf conditions." That’s the one to aim for, but it’s a week and a half away, so keep an eye on it.
The rest of the 16-day window is small, weak, and often onshore. The energy dips to double digits (52 to 73) with tiny swells. Not worth it.
The best of the first week is Sunday morning, 6th September. Clean, 5 ft, light wind. For the long-range, Wednesday morning, 16th September is the one to watch: glassy, 5 ft, strong energy. That’s your best bet.
Rusty.
