The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming our way at El Olon de Ilo over the next couple of weeks.
First up, the waiting game. There’s nothing worth paddling out for right now—today and tomorrow are a write-off. The first real chance to get wet is Thursday morning the 13th of August, but even then it’s marginal. The water temp is sitting at 65°F, which is a touch warmer than normal for this time of year—no need for a thick steamer.
The real start of things kicks off Friday morning the 14th of August. We’ve got a clean 4 ft swell coming from the SW with a period of 16 seconds—proper groundswell with some push behind it. Winds are light cross-off from the S at 6 mph, so the face should be tidy. The combined energy reads 969 (moderate wave energy), and it’s an advanced reef break, so this is for experienced surfers only. It doesn't get crowded here, which is a bonus. This Friday morning is likely the standout of the whole run—good swell, clean offshores, and a quality wave.
Saturday the 15th is still fun in the morning, with clean 4 ft SW groundswell and light cross-off winds, but the energy drops to 590. From Saturday afternoon through Sunday the 16th, it gets a bit messy with cross-shore winds and a smaller, less organised swell.
Hold onto your leash for Monday the 17th of August. The morning looks average, but by Monday afternoon we see a glass-off—NNE winds at 0 mph, glassy conditions, and 4 ft SW swell with 14-second period. The combined energy reads 603. That afternoon session is a hidden gem in the forecast: glassy, hollow enough, and no one around.
Tuesday the 18th keeps the glassy theme in the morning with WSW winds at 3 mph, 4 ft SW groundswell, and clean conditions. Tuesday afternoon sees a slight wind pick-up but still cross-off and tidy.
Then we go into a bit of a lull. Wednesday the 19th brings a bump in size to 5 ft but with a short 10-second period and stronger S winds at 12 mph—choppy and less appealing. The next few days through to the 26th are all small—around 2 ft to 3 ft—mostly from the SSW with short periods. A few glassy windows appear, like Saturday the 22nd afternoon with 3 ft SSW and calm winds, but the energy is weak (256).
Now, if you can wait, there’s something cooking for Thursday the 27th of August. Both morning and afternoon show 4 ft SW groundswell with a 16-second period, light cross-off winds from the S at 6 mph, and combined energy up at 951—moderate to strong. Expect very good surf conditions. It’s too far out to lock in, but it’s got that long period groundswell feel—perfect for this reef.
So to sum it up: Friday morning the 14th is your prime call this week, with Monday afternoon the 17th as a sneaky glassy standout. The far end, Thursday the 27th, has promise, but don’t book your flights yet.
Rusty out.
