The Lowdown
Alright, crew, Rusty here. Let’s break down the next couple of weeks. It's a bit of a rollercoaster, with some rough stuff early on, but there are a few clean windows that are worth your time if you're patient.
The Early Grind
The first few days are a bit of a letdown. We're looking at a gap with no good waves, and the first real pulse on Friday afternoon is pretty marginal. The surf is there, maybe 7ft, but the light cross-shore wind puts a bump on it. The water is sitting around 63°, which is a couple degrees colder than usual – you'll feel that in the lineup.
The weekend is more of the same. There’s a consistent 5-6ft of swell, but the winds are all over the place, making it lumpy and choppy. Then, it all kicks off on Monday. The swell jumps to a strong 7ft, building to over 11ft by the afternoon with a huge jump in energy. But it comes with strong winds and rain. It’s a monster, but it’s a messy, blown-out monster. Only for the crazy ones.
Mid-Week Mess
Tuesday and Wednesday stay big and bumpy, with waves around 7-11ft. The energy is enormous, but the onshore winds just ruin it. It’s a lot of water moving, but the quality is terrible. You’d be battling the chop more than riding the waves.
The First Clean-Up
The first sign of good conditions comes on Thursday the 20th. The wind finally drops to a light cross-off, and the swell is still a solid 10ft from the WSW with a good 16-second period. It's powerful and now, finally, clean. This is a day for experienced surfers only. Friday the 21st also looks good, with 6-7ft surf and clean conditions. This is where things start to get interesting.
A Fade, Then the Big One
The end of the week fades a bit, and Sunday is a total loss with strong onshore winds again. Early next week is more of the same messy stuff. But then, circle Tuesday the 25th on the calendar. We're looking at a massive pulse of energy, with a swell of over 11ft and a long 17-second period. The winds are fresh, but they're cross-off, keeping it clean. This is an experts-only day with serious potential. It’s a long-range call, so it’s promising but not set in stone.
The Clean Finish
The final days of the period, especially Thursday the 27th and Friday the 28th, look sensational. Winds become light and variable, and we get periods of dead-calm, glassy conditions. The energy remains. The best of the best looks set for Friday afternoon when the wind goes glassy and a solid 10ft, 19-second southwest groundswell rolls in. This is the one we’re all waiting for – a true standout for the experts out there.
Keep an eye on the forecast and be ready to move when the wind drops. There are some serious waves on the way. If you've got the skills, the end of the month could be one for the books.
Rusty, signing off.
