Sakawa River Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for the Sakawa River. I gotta be straight with you—the first week and a half is a real tough go. We’re looking at tiny, weak waves with poor conditions, so don't even bother waxing up until the 25th of August. That’s a solid week of flat, onshore dribble.

The first real sign of life shows up on Tuesday the 25th of August. Late in the afternoon, we’ve got a 5ft swell from the SSE, pushing in with a long 13-second period. The wind is onshore, though, so it’s a bit messy. The combined energy is moderate at 718. Still, it’s a glimmer.

The standout window, and I mean the one to circle on the calendar, is the morning of Saturday the 29th of August. The swell drops a touch to 5ft from the SSW, but it’s carrying a very long 14-second period. The real kicker is the wind: dead calm, glassy conditions. The water temperature is about 81°, which is average for this time of year. The combined energy is strong at 945. That’s the session to aim for – clean, lined-up waves before the wind fills in.

Before that, from the 27th through the 28th, we get a bigger pulse. On Thursday the 27th, the swell hits 7ft from the S with a 15-second period and a massive 2074 combined energy. That’s powerful, but the wind is a stiff cross-offshore at 16 mph, keeping it clean. It’s a solid, expert-level wave. The Sakawa River is a river mouth, so with that long period, the waves will be set-y and clean off the bank. Just be aware that with that size, it’s not for beginners.

The week after that, into early September, the swell drops off again, but we get another pulse on the 2nd of September. That Wednesday morning sees a 6ft swell from the ESE with a 12-second period and clean cross-offshore wind. The energy is 1087. Not a standout, but a decent option if you’re desperate.

So, to wrap it up: the first week is a write-off. The best window is the 27th to 29th of August, with the absolute top pick being the glassy morning of the 29th. The river mouth handles the long period well, so expect some nice, pushy lines. The crowds are noted as "sometimes" here, so you might have a few others after the same wave.

If you’ve got the gear and the nerve, the bigger days on the 27th and 28th will fire for the experienced crew. For the rest of us, hold out for that Saturday glass-off.

Stay salty,
Rusty
