The Lowdown
Alright crew, Rusty here. Let’s break it down for the next couple weeks. Water temp is 85°F, right where it should be for this time of year. We start off a bit messy, but a big SSW groundswell is stacking up, and when it hits, it’s going to be a proper event.
Thursday the 6th afternoon shows a 7ft swell from the SSW, with a very long 16-second period, but the wind is from the NNW at 9 mph, so it’s choppy. The energy is strong (2102), but the conditions are poor.
Friday the 7th: swell builds to 8ft–8ft, period 17–18 seconds, but the wind stays cross-on from the north all day (12 mph dropping to 9 mph). Choppy and bumpy. Not the one.
Saturday the 8th morning is still a bit cross-on, but the afternoon cleans right up. Wind goes east at 3 mph, cross-offshore, and the swell is a clean 7ft from the SSW, 16 seconds, with 2379 energy. This is a solid, clean session for intermediates.
Sunday the 9th: flat. Zero swell. Stay home.
Monday the 10th: a tiny 2ft pulse rolls in with a 24-second period, energy at 368. Wind is offshore and clean, but it’s just too small to ride.
Tuesday the 11th morning sees a better 4ft from the SSW, 19 seconds, energy 1004, with clean offshore wind. A small but clean groundswell at Hideaways. Fun and quiet.
Then we hit a flat spell from Tuesday afternoon through to Friday morning (14th). A few tiny pulses (0.7ft–0.8ft) but nothing worth paddling for.
Saturday the 15th morning brings back 3ft from the SW, 17 seconds, energy 580, with glassy offshore conditions. A clean, gentle morning.
Sunday the 16th and Monday the 17th hold 3ft–3ft, SW, 14–16 seconds, with offshore winds. Monday afternoon (17th) is a gem – glassy, 3ft, energy 816, and a clean SW swell.
Now the big stuff. Tuesday the 18th: morning hits 7ft SSW, 16 seconds, energy 3017, with moderate offshore wind. Afternoon jumps to 8ft, 16 seconds, energy 3185, and light offshore wind. This is excellent, but 8ft is expert-only.
Wednesday the 19th is the peak. Both sessions deliver 10ft from the SSW, 18 seconds, energy over 5500. Winds are gentle offshore or cross-off. This is a world-class, heavy, powerful groundswell. Experts only.
Thursday the 20th holds at 10ft, 17 seconds, energy still over 5200. Clean and powerful.
Friday the 21st winds down to 8ft, 16 seconds, energy around 3500–3182. Still excellent and clean.
The standout? No question – Wednesday the 19th. That 10ft, 18-second SSW groundswell with clean offshore wind is the absolute best of the run. If you’ve got the skills, that’s your day.
Rusty.
