The Lowdown
Righto, let’s have a proper look at the run ahead. The early part of the window is shaping up nicely, with a solid, long-period groundswell from the west-southwest aimed straight at Cozies and Geeries. This is a reef and point setup, so it’s gonna handle that long-period energy well, giving some proper lines. The best of the bunch lands on the 13th and 22nd, but let’s walk through it.
Wednesday the 12th afternoon sees that 7 ft swell from the WSW with a 15-second period, and the wind is a light cross-off. The water’s sitting at 64°, which is about 2° cooler than the long-term average for this time of year – nothing too wild, just a touch on the fresh side. The combined energy is moderate at 2009, so there’s push behind it. It’s a solid session for experienced surfers.
Thursday the 13th morning is the real standout. You’ve got the same 7 ft WSW swell but the period has bumped up to 17 seconds – that’s proper groundswell. The wind is glassy, offshore from the ENE at just 3 mph. The energy has jumped to 2862, and the surf is clean as a whistle. This is the pick of the first week for anyone who can handle a reef. The afternoon stays clean with a cross-off, but it’s a touch windier.
Friday the 14th carries on the run with 7 ft to 7 ft WSW swell, 16-second period, and light cross-off winds. The energy is still strong, 2198 in the morning. Nice, consistent waves for experienced paddlers.
Saturday the 15th sees the swell drop to 6 ft, and the wind gets messy. Morning is a moderate cross-shore with a chop, not worth the paddle. The afternoon improves slightly with a light cross-on, but it’s not clean.
Sunday the 16th is a write-off. Fresh cross-shore winds and lumpy cross-chop on the 7 ft surf. Not good.
Monday the 17th is a total mess. Strong onshore winds and rain showers, with the swell jumping to 12 ft from the west. The afternoon is a near gale cross-onshore – blown out completely. This is kite-surfing conditions, not paddle surfing.
Tuesday the 18th sees a massive 12 ft W swell, but the wind is a cross-off in the morning, so it’s clean. The energy is 6432, very strong. Only for experts at this size, and the reef setup will be handling it. The afternoon gets a cross-on wind, so it’s a bit choppy.
Wednesday the 19th is back to poor. Strong onshore winds and a risk of thunderstorms. The swell drops to 6 ft, but the wind wrecks it.
Thursday the 20th has a huge 15 ft W swell in the afternoon, but the wind is a fresh cross-onshore. Energy is 9716, very strong, but it’s lumpy and blown out. Only for experts, and even then, it’s not clean.
Friday the 21st brings some relief. 10 ft WSW swell, 14-second period, with a clean cross-off wind. The energy is 3197. It’s big, but it’s rideable for experienced surfers.
Now, the standout of the whole run: Saturday the 22nd. Morning is glassy – zero wind from the SE. The swell is 10 ft from the WSW, 15-second period, and the energy is 3427. The afternoon is just as good with a light cross-off. This is the best on offer. Clean, powerful, long-period groundswell at a point and reef. It’s a date to circle. The crowds are listed as “sometimes,” so you might have company, but the quality will be worth it.
Sunday the 23rd drops off. 7 ft swell with a moderate cross-shore and chop. Not great.
From Monday the 24th through to Thursday the 27th, it’s a long run of poor conditions. The wind is onshore or cross-onshore, the swell is messy, and the energy drops. The 27th afternoon sees the swell shrink to 3 ft with a 17-second period, but it’s choppy and weak.
Thursday the 27th afternoon is the last record, and it’s a poor one. After that, there’s a gap of several days with no recommendations.
In short, the first week has a few gems, especially Thursday the 13th morning and Saturday the 22nd. The 22nd is the true standout. The second week is mostly a bust with that big, windy swell. If you’re an expert, the 18th and 21st might be worth a look, but the 22nd is the one to plan for.
