The Lowdown
Alright, let’s get into it.
The first proper window is Thursday afternoon. Clean 1.5m of SW groundswell with a 15-second period, and that ESE breeze is just a whisper. The energy is moderate (1137), and it’s glassy. This one’s for the experienced crew—clean and punchy.
Friday morning’s a bit more mixed. Swell drops to 1.4m, period holds at 15 seconds, but that N wind at 15 km/h puts a bit of cross-shore bump on it. It’s okay, but not a patch on Thursday. The afternoon goes downhill as the wind swings onshore.
The weekend’s all over the place. Swell builds—2.1m Saturday, 2.3m by Monday—but the wind keeps messing it up. Onshore, cross-onshore, lumpy. Good energy, poor shape. I’d be sitting this one out.
Monday morning though, that’s a different story. 2.3m of SW swell, and the wind goes SE at 10 km/h. Clean cross-off. The period is a touch shorter at 14 seconds, but it’s still groundswell. Energy’s up (2171). It’s a bit of a paddle, but if you want a clean one, this is your alarm call.
Now, Saturday the 19th is where things get serious. Swell jumps to 2.5m from the WSW, and the energy is huge—4631 on the morning. That’s proper power. The morning wind is SSE at 20 km/h, cross-off, so it’s clean but packing a serious punch. Experts only. Then Sunday the 20th gives you a bit of a breather with 1.9m and a clean SE cross-off.
Skip the middle of that week—windy and messy. Tuesday the 22nd brings 3.5m of swell, and with S winds at 30-35 km/h, it’s going to be a chaotic, lumpy mess. Not one for the faint-hearted.
The standout is Wednesday morning the 23rd. 3.0m of SW groundswell with a 16-second period, and the wind is SE at 25 km/h, giving a clean cross-off. Energy is massive at 4938. Big, powerful, and if you’ve got the nerve, this is the one.
And to finish, Thursday the 24th and Friday the 25th both have clean morning windows. Offshore or cross-off winds, and solid 2.2m to 2.3m SW swells. Reliable days to round it all off.
Water temp is about 19°C, which is normal for this time of year.
Rusty out.
