Onjuku Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’m looking at the next few weeks for Onjuku. I gotta be straight with you—this is a bit of a slow burn. There’s a long dry spell at the start, so don’t get your hopes up for the first week. We’ve got a decent window of cleaner conditions later on, but you’ll need to be patient.

The first notable surf comes in on Monday, July 20th, but it’s marginal. The water temp is sitting at a comfortable 77°, which is pretty much spot on average for this time of year. The real action doesn’t start to shape up until the early morning of Monday, July 21st. That’s when we get a shift. The wind goes light offshore from the NE, and the swell turns on at 4 ft from the east with a nice 11-second period. That’s a proper groundswell, and the combined energy is solid (393). It’s going to be clean, but keep in mind that long period swell like this can make the waves a bit straight at beach breaks; Onjuku is an exposed spot, so with that east direction, it could work. The crowd factor is listed as “sometimes,” so you might have some company.

The best windows in this whole outlook are the mornings of Saturday, July 25th, and Sunday, July 26th. Saturday morning is a real standout. The wind goes dead glassy at 0 mph, and we’ve got a 4 ft swell pushing in from the south. The period is a short 6 seconds, so it’s a bit of a windswell, but the glassy conditions will make it look fun. The combined energy is moderate (291). Sunday morning is also strong: 4 ft from the ENE with a clean cross-offshore breeze, and the energy is a bit lower (269), but it’ll be clean. The following Monday morning, July 27th, keeps the good run going with 3 ft from the SSE and a long 10-second period, which is a nice combo for cleaner lines. The energy is moderate (300).

The very last good call is on the morning of Tuesday, July 28th. It’s tiny at 2 ft from the SSE with a 9-second period, but the wind is glassy, and the energy is still moderate (212). If you’re just looking for a paddle, it’s a winner.

The standout for the whole period is the Saturday morning, July 25th. That glassy, clean morning with the 4 ft south swell is the best on offer. The Sunday morning, July 26th, is a close second with that clean cross-offshore wind. For the rest of the second week, things get onshore and messy again.

So, to sum it up: the first week is a write-off. The second week has a few solid mornings starting July 21st, but the real gems are the glassy mornings on July 25th and 26th. Don’t sleep on those.

Rusty.
