El Olon de Ilo Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cooking at El Olon de Ilo.

We’ve got a pretty solid run of surf on the horizon, starting this Thursday and stretching all the way through the 16-day window. The standout period is really the first week, where we see a nice combination of size, clean conditions, and that long-period groundswell energy. This is a reef break, and for an advanced crew only. It’s inconsistent, so you need to be patient, but when it fires, it’s a gem. The water temp is about average for this time of year.

The week kicks off Thursday, September 3rd. Thursday morning is a bit iffy with a light cross-shore at 4ft (moderate energy at 939), but the afternoon is where it’s at. The wind goes glassy, the swell holds at 4ft from the southwest with a very long 17-second period, and the energy jumps to 1044. That’s a proper groundswell pulse, and with glassy conditions, it’s going to be uncrowded and absolutely perfect for those who can handle a reef setup. The long period will make the waves lined up and powerful.

Friday, September 4th sees the swell building to 5ft in the morning (1198 energy), but the wind stays a light cross-shore, keeping things a bit bumpy. By Friday afternoon, it’s pushing 6ft (1258 energy), which is getting into big territory for most, and it’s still cross-shore. Still a solid option for the experienced.

Saturday, September 5th, a little smaller in the morning at 5ft, but the real magic is Saturday afternoon. Glassy again, 4ft southwest swell, 13-second period, and energy at 843. That’s a lovely clean window.

Sunday the 6th drops right off to 2ft, and the energy plummets. Not worth paddling out.

Monday the 7th through Thursday the 10th is a solid run of clean to glassy conditions, with swell sitting between 3ft and 4ft. Winds are light and either glassy or cross-offshore, giving you clean faces. The energy stays in the moderate range (700-880). This is consistent, user-friendly groundswell. Tuesday the 8th is particularly tidy, with glass all day and 4ft from the SW.

The second week sees things taper. From Friday the 11th, the swell drops and the energy falls below 400. There’s a real gap from the 12th to the 13th where it’s marginal at best, only 3ft and messy cross-shore winds. Not worth the effort.

We get a little pulse back on Monday the 14th and Tuesday the 15th, with clean conditions and 3ft to 3ft south-southwest swells. Energy climbs back to 400-460. A reasonable option for a quiet session.

The best of the second week, and honestly a real standout for the whole forecast, is Wednesday the 16th. That morning brings 5ft from the southwest with a 14-second period, clean cross-offshore wind, and energy hitting 1005. That’s a solid, powerful groundswell day, but it’s only for experts at that size. The afternoon gets a bit messier with cross-shore wind.

If I had to pick the single best session, it’s that Thursday afternoon, September 3rd. Glass, long period, uncrowded, perfect conditions for a reef break.

Stay patient, stay picky.

Rusty.
