The Lowdown
Alright, Rusty here. Let’s have a look at the coming swell window.
We’ve got a run of surf coming up, starting this Friday, but don’t get too excited yet. The first few days are a bit of a mixed bag with some lumpy, cross-shore wind messing up what could be a decent swell. The real standout window is Monday 7th through Tuesday 8th, and then again later in the second week around Monday 14th and Tuesday 15th.
Friday 4th September kicks things off at Cozies and Geeries with a solid 12 ft swell from the WSW, but a fresh cross-breeze from the SW at 19 mph keeps things lumpy. The combined energy is strong at 3531, but the quality is marginal. Friday afternoon sees the wind ease to 9 mph cross, and the swell drops to 10 ft with a nice 14-second period – still a bit of cross-chop, but cleaner. The water temp is 64°, about normal for the time of year.
Saturday 5th is a write-off. A cross-onshore wind from the NNW at 19 mph with light rain and a risk of thunderstorms. Swell is 8 ft but messy. Not worth paddling out.
Sunday 6th looks better. A cross-offshore breeze from the SSE at 22 mph in the morning, with 10 ft swell and 12-second period – clean. The afternoon turns offshore from the SE at 19 mph, dropping to 8 ft but with a 13-second period and fresh, clean conditions. The energy is still strong (2886). This is the warm-up.
Monday 7th September – now we’re talking. Morning glass-off with an ESE breeze at 12 mph, offshore, and a 8 ft swell with a very long 17-second period. The combined energy is 3161. This is excellent for experienced surfers. The point and reef setup here will love that long-period groundswell – expect clean, lined-up waves. Afternoon stays clean with a cross-offshore breeze. This is a top pick.
Tuesday 8th September is just as good. Morning offshore ESE at 12 mph, 8 ft swell, 17-second period, energy 3625. Afternoon offshore SE at 16 mph, same swell height and period, energy 3730. Two solid days of clean, powerful surf. If you’re an experienced surfer, this is the best of the lot.
Wednesday 9th eases off a bit. Swell drops to 7 ft in the morning, 7 ft in the afternoon, but still clean with a 16-second period. A nice option for those who want a lighter crowd – but note, this break can get crowded sometimes.
From Thursday 10th through Saturday 12th, things drop right off. Swell drops to 5 ft and below, with shorter periods. Not worth the effort.
Sunday 13th September sees a big jump in size but with terrible wind. A 13 ft to 15 ft swell from the W, but a strong cross-onshore breeze at 28 mph makes it a washing machine. Energy hits 7233 in the afternoon, but it’s messy and blown out. This is expert-only and probably more fun for kite surfers.
Monday 14th September – back on. A 13 ft swell from the W with a 14-second period, but the wind swings to a cross-offshore from the S at 19 mph, keeping it clean. Energy is 6706. This is big and powerful, so only for experienced surfers. The afternoon drops to 12 ft but stays clean. A solid second-week standout.
Tuesday 15th is another good one. A lighter 8 ft swell from the WSW, 13-second period, with a light offshore from the SE at 6 mph in the morning. Energy is 1868. Clean and fun. Afternoon gets a cross-offshore breeze, still clean.
Wednesday 16th is smaller – 4 ft – but offshore ESE breeze keeps it clean. Not a standout but a nice end to the run.
Thursday 17th brings a new pulse: 8 ft swell from the WSW with a very long 18-second period, but a moderate cross-breeze keeps it a bit choppy. Still worth a look.
From Friday 18th onward, the wind turns onshore again and the quality drops. By Saturday 19th, a near gale from the WSW at 34 mph makes it a write-off.
So, the clear winners are Monday 7th and Tuesday 8th September for the best combination of clean, offshore wind, long-period groundswell, and strong energy. If you miss that, Monday 14th September is the next big, clean swell for the experienced crew.
Stay stoked.
