Ilot Sancho Surf Forecast and Surf Report

Righto, let’s have a look at what’s in store for Ilot Sancho (reef). The first thing to say is you’ve got to be patient. The start of this 16-day window is a write-off. Friday 28th August through to Sunday 30th August is a total mess. That big, long-period SW groundswell is pumping in at 13ft with a 16-second period, but the wind is howling from the SSE and SE at 22 to 25 mph, making it cross-on or cross, and the description is just poor. The combined wave energy is massive—around 9296 on the Friday morning—but it’s lumpy, choppy, and absolutely not worth paddling out. That’s three days of no-go. You’d be better off watching from the cliffs.

Then we start to see a slow improvement. Sunday afternoon the 30th brings a bit of hope: the swell drops to 7ft from the SSW, the wind swings to E at 22 mph and goes cross-off, so it cleans up. But the combined energy is still high at 3062, and while it’s “clean,” it’s only a marginal score because the tide might be playing games. Monday 31st and Tuesday 1st September keep that cross-off from the E at 16 to 19 mph, with 10ft to 8ft swell dropping to a 9-second period. It’s clean but that shorter period means the waves won’t have much shape or power—it’ll feel a bit fat and weak for a bigger reef break. The energy numbers come down to around 2182 to 1270.

The standout window is Wednesday 2nd and Thursday 3rd September. Wednesday morning has 8ft from the east with a 10-second period, light to moderate breeze from the E at 12 mph, cross-off and clean. The combined energy is 1415, which is moderate but well-directed. The wind is offshore enough to keep the faces smooth, and that swell direction is right in the optimum SW zone, so the reef should line up nicely. Thursday 3rd morning still holds clean, but the energy drops to 1116 and the wind picks up a touch. If you can, Wednesday is the pick of the first week.

From Friday 4th September through to around Tuesday 9th, it gets tricky again. The wind goes cross with moderate to fresh breezes from the ESE, and the swell mixes up between weaker east pulses and bigger, longer-period SW groundswells. On Saturday 5th September, there’s a sudden 4ft from the SW at 18 seconds, then 6ft from SW at 17 seconds on the Saturday afternoon. The combined energy jumps up to 2646 that afternoon, but the wind is still cross at 19 mph, so it’s lumpy. Not a clean day for this reef.

The long-range standout is a bit further out. Look at Wednesday 10th September. That morning has 5ft from the SW with a 16-second period, and for the first time the wind drops to just 6 mph from the SE—a light breeze with only small ripples. It’s cross-shore, but at that speed it’s essentially glassy. The energy sits at 1736, so it’s moderate, but that long period groundswell combined with near-calm wind on a reef setup like Ilot Sancho could produce some clean, well-shaped walls. It’s a bit of a tease because by the afternoon the wind swings and picks up, so you’d want to be there early. The last few days from Thursday 11th to Saturday 12th September are a mix of small, weak swell and choppy conditions, not worth chasing.

Overall, this isn’t a classic run. The best you’ll get is a couple of clean sessions around Wednesday 2nd/Thursday 3rd September and maybe Wednesday 10th September if the wind holds. That long-period SW groundswell that appears on the 5th and 7th is powerful but always has lumpy cross-wind spoiling it. Just keep an eye on the forecasts—if that wind lightens up, Ilot Sancho can handle a lot of size, but for this window, pick your moment. The water temp is about average for the time of year, so no surprises there.
