The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you. We’ve got a solid 16-day stretch ahead, but it ain’t gonna be all firing at once. There’s a bit of a slow burn to start, and we’re looking at a good chunk of time where the ocean’s just… ordinary. But don’t write it off, because there’s a proper window of clean waves on the horizon that’s worth keeping an eye on.
We kick things off at Guidel Plages this Monday with clean, glassy conditions. It’s small though, around the 3ft mark, with that nice west swell wrapping in. The water’s sitting at 66°F, which is a touch warmer than usual for this time of year. The energy’s there but it’s all a bit meek – we’re only looking at a combined energy of 131, so it’s a weak pulse. It’s surfable, but you’ll be working for it.
After that, we’re going into a bit of a flat spell. Tuesday through Thursday, the swell drops right off, bottoming out at 2ft on Tuesday and even down to 0.6ft on Thursday afternoon. There’s a little window of offshore winds on Wednesday and Thursday mornings, but with waves that small, you’re going to be on a longboard, just floating around. We’re talking a few days of nothing juicy.
Then we get a bit of a kick on Friday the 25th and Saturday the 26th. It’s not huge, but the swell picks back up to 5ft on Friday morning. Winds are cross-offshore, so the surf should be clean, even if the quality is only marginal. The energy jumps to 1019, which is a solid jump into moderate territory. But again, the conditions are just okay, not amazing. The weekend looks a little weaker and more cross-shore, so we’re still waiting for the main event.
Now, here’s where it gets interesting. Sunday the 27th is the standout in this whole stretch. The morning is looking proper. We’ve got a 7ft WSW swell, with a clean, cross-offshore breeze out of the ESE. And look at that juice – combined energy of 858. The reports are saying "expect very good surf conditions." This is the one. The break is a beach and reef setup, and with that west in the water, it should be handling it well. The only slight downside is the period is 10 seconds, so it’s not super long, but the clean conditions will make it feel better.
Monday the 28th has the biggest number on the board with a 10ft swell and a combined energy of 1244, but it’s messy. We’ve got a SE wind which is cross-shore, and that light chop is going to knock the quality off. Plus, that size is pushing well into the “experts only” territory. The afternoon goes bad with a strong SW onshore. So, as tempting as the size is, it’s not going to be the day.
After that, it fades out. The last few days of the window are back to small and clean, but nothing to get excited about. The standout remains Sunday the 27th. If you can get out for a dawny, do it.
Remember, this is a long-range call, so treat that Sunday as promising but not set in stone. Keep an eye on the charts. For now, that’s your lot.
Stay stoked,
Rusty.
