The Lowdown
Alright crew, Rusty here. Let's talk about the stretch ahead at Ilot Sancho. I’ve been staring at the charts for this one, and it’s a proper mixed bag with a big window of opportunity if you’re patient, and a warning for the faint of heart.
The first week is a bit of a grind. We're looking at days of cross and cross-off winds making things a little lumpy. The swell is on the smaller side, mostly around the 3 to 4-foot mark, with short-period windswell out of the east. It’s not a total write-off, but it’s not going to be a classic. There’s a brief tease on Friday the 21st when a new southwest swell starts to show, still a bit small at 4 to 5ft and a bit weak in energy, but the morning looks clean with a gentle breeze. It’s surfable, but you’ll be hunting for the better ones.
Then, the game changes. The swell really starts to fill in on Sunday the 23rd. We see the southwest energy building, and the sea state jumps to a respectable 8ft with a solid 14-second period. The energy numbers are climbing, which shows us there’s some actual power behind it now. The wind remains cross-off and clean, so the surface should be smooth. This is when things start to get interesting.
The real standout, and I mean the one I’d be checking my calendar for, is Tuesday the 25th. The morning shows a very healthy 10ft of southwest groundswell at a long 17-second period, and the energy is near 5000. That’s proper, powerful stuff. But hold on, because by the afternoon, the model is telling us the swell is topping out at 11-12ft. The wave comment even says the 'wind and tide favorable, but the swell is predicted to be too big for this break'. This is a serious amount of water for Ilot Sancho. Even though the charts are clean, this is expert territory. If you're not on the shortboard and have your wits about you, this could be a beating. While a long period like that is amazing for points and reefs, it can make a beach break close out, so you have to know this spot well. Still, the raw power on that afternoon is about as good as it gets for the experienced surfer.
The rest of that week stays big, but the winds become more of a cross-shore breeze, and it gets lumpier. The swell stays well over 8ft, and it’s just too big and unruly for most people. By the time we get to the following week, from the 28th onwards, the wind starts to pick up seriously, hitting 19 mph and more. The swell is still there, but it’s messy and the conditions are not going to be pretty.
A quick word on the water: with the first proper swell, the water temp is about average for the time of year, so a decent spring suit is your friend. Not too cold, not warm.
Also, for a spot like this that can be fairly consistent, the crowds are a real factor. When that Tuesday the 25th swell hits, you can bet there will be plenty of locals out. Expect it to be busy.
So, there you have it. A slow start, a fun but short window on the 23rd, and one massive, spectacular, and dangerous day on the 25th. Get your fitness up for that one, and respect the ocean. It’s going to be a proper tow-in day for the fearless. For the rest of us, it might be a better day to watch from the shore.
This is Rusty, signing off. Get after it.
