The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for Cozies and Geeries. This is a reef and point set-up, so it likes a clean, organised swell, and when the conditions line up, it can be a gem. The water sits at 63°F right now, which is about normal for this time of year with a slight cooling offset, nothing too wild.
First up, we’ve got a bit of a slow start. The forecast kicks off with Saturday the 12th, but honestly, you’re better off giving it a miss. We’ve got a 8ft swell from the WSW, but with a 12 mph cross-on wind, it’s going to be choppy and messy. The combined energy is moderate at 1972, but the wind is just ruining it.
Sunday the 13th looks much the same – lumpy and cross-on, with poor surf conditions. Hold out.
Now, Monday the 14th is the first real standout. The swell holds at 8ft from the WSW, with a sweet 14-second period. The wind goes *glass-off* offshore from the SSE at 3 mph in the morning, then picks up to 16 mph offshore in the afternoon. Either way, it’s clean. The wave energy sits at 2107-2167, a good solid push. This is a great window for experienced surfers – the size is up there, but clean, lined-up waves are on the cards. Crowds are sometimes an issue here, so be prepared for a few others who’ve been waiting for this.
Tuesday the 15th and Wednesday the 16th drop off in quality. The swell fades a bit and the winds turn cross or onshore, so the magic fades. Thursday the 17th is a write-off with strong cross-onshore winds.
Friday the 18th is a warning. That morning brings a 8ft swell from the WSW with a very long 16-second period, but the wind is howling at 22 mph from the north with a risk of thunderstorms. The energy spike is big at 3111, but it’s going to be lumpy and dangerous. Friday afternoon gets even worse with wind gusts. This is a day for the kite crew, not paddle surfing.
We get a messy weekend, but then Sunday the 20th shows up with a big improvement. The morning has a clean 7ft swell, light wind, and the afternoon bumps up to 8ft with a massive 17-second groundswell period and energy of 4060. The wind is cross-off, keeping it clean. The period is long, so expect those long waits between sets, but the shape on this reef and point should be well worth the patience.
Moving through the next week, Monday the 21st afternoon is another strong call. The swell is 7ft from the WSW, 16-second period, and the wind drops to a dead calm – glassy, clean. Excellent conditions for experienced surfers.
The biggest highlight of the entire run looks like Thursday the 24th. We’re talking an 12ft swell from the WSW with a 19-second period. The combined energy is enormous at 9244. Winds are cross-off from the south at 12 mph, keeping it clean. Now, 12ft is solid, expert-level territory, and with such a long period, it will really unload on this reef and point set-up. Spectacular waves for the crew that can handle it, but not for the faint-hearted.
Friday the 25th is also solid, with 8ft swell and offshore winds, though it’s a step down in power from Thursday. After that, the swell fades out into the last weekend of September with smaller, cleaner but less exciting surf.
All in all, Monday the 14th and Thursday the 24th are your two true standouts. The 14th for that first clean shot of real swell, and the 24th for the pure power and size. The spots can get busy though, so plan for a few others in the water.
Rusty, signing out.
