Ilot Sancho Surf Forecast and Surf Report

Alright, let's get into it. This is a tough stretch—a real waiting game. If you're on the Big Island, the swell at Ilot Sancho (Big Island) is set to be persistent, but the conditions are going to fight us for a while. The water is running a touch warmer than normal right now at 77.2°F.

From this afternoon, Monday the 6th of July, through Wednesday the 8th, it's honestly not worth paddling out. We've got a solid 6.2ft to 11.5ft of swell rolling in, but the cross-onshore and cross-shore winds are going to wreck it. The energy is there, but it's going to be lumpy, messy, and blown out. Not the wave we want.

We finally get a reprieve from Thursday morning, the 9th of July. The wind swings more cross-offshore, and the surf cleans up nicely. Swell drops to a manageable 5.6ft to 6.9ft out of the SSE and SE, with a moderate breeze keeping it clean. Friday, the 10th, stays clean and small, around 4.9ft to 5.6ft from the east. Not pumping, but rideable.

Now, here's where it gets interesting. From Saturday the 11th into Sunday the 12th, we see a jump in quality. The swell direction swings around to the southwest, and the period goes long—15 to 16 seconds. That’s proper groundswell. This is the standout window. Saturday morning sees 5.2ft SW swell with a 16-second period, and Sunday morning bumps up to 7.2ft from the SW at 15 seconds. The wind stays cross-offshore and clean all weekend. This is the one to target. This long-period SW swell will wrap in nicely at a reef like Ilot Sancho, giving it shape and power. Just keep in mind that long-period stuff can be a bit straight at beach breaks, but on a reef, it's gold.

Monday the 13th and Tuesday the 14th stay on the cleaner side but gradually drop off. Swell is 4.6ft to 6.6ft from the SW, still with decent periods in the 13-14 second range. Still worth a paddle if you missed the weekend.

The rest of the second week into the 21st looks more marginal. Swell sizes bounce between 3.9ft and 8.2ft, but the wind, while still cross-offshore, stiffens up, and the period on the E swells is often short—around 8 or 9 seconds. The long-period SSW pulses on the 16th and the 20th-21st bring the energy back up, but they come with cross-shore winds and lumpy conditions, which kills the magic. The 3.9ft days on the 18th and 19th are too small and weak to get excited about.

If you're a beginner, be careful on the 7.2ft - 8.2ft days unless the conditions are glassy, which isn't the case here. Anything over 8.2ft during the messy Wednesday the 8th is for experts only.

Bottom line: the standout window is Saturday the 11th through Sunday the 12th, with that clean, long-period SW groundswell. That's the one to circle on your calendar.
