Sakawa River Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming down the line for the Sakawa River area.

Right off the bat, the first few days are a bit of a write-off. Friday the 7th of August has some solid swell—around 6ft from the south, with a long 12-second period—but the wind is a mess, and conditions are marginal at best. The combined energy is pumping at 1240, but with cross-onshore wind and a "marginal" call, it’s not worth paddling out for anything special. Friday afternoon only gets worse.

Saturday the 8th of August is where it gets interesting. The morning glass-off is a beauty: light wind from the SSE, near-calm, and 4ft of south swell at 11 seconds. The combined energy is a moderate 425, but the glassy surface means clean, fun waves for an intermediate surfer. This is the standout of the early period. Sakawa River is a river break, and with that long-period south swell, expect the wave to hold its shape nicely. Water temp is about average for this time of year, so nothing wild there. Crowds are sometimes a factor, so you might have company, but the clean conditions should make up for it.

Sunday the 9th sees a drop in swell size to 3ft, still with a nice 13-second period from the ESE, but the wind swings cross-on and conditions turn average. Not a total loss, but nothing to write home about. Monday and Tuesday are even smaller—dropping to 2ft and lower—with cross-shore or onshore winds, so mostly poor surf.

There’s a bit of a lull through the middle of the week. Wednesday the 12th morning goes glassy again but with only 2ft of swell, so it’s small and ordinary. Thursday and Friday are flat-ish and windy.

Now, here’s the long-range call. Sunday the 16th of August afternoon looks promising. We get 5ft from the ESE at 11 seconds, combined energy of 537, and glassy wind conditions. That’s another clean window, but it’s over a week away, so keep an eye on it—forecasts can shift. The Monday morning after that has 4ft with a clean cross-off wind, but the wind picks up strong through the afternoon, so the window is narrow.

After that, the swell drops off quickly into the second week, with tiny waves and mostly poor conditions through to the 22nd. The morning of Friday the 21st has a glassy 2ft south swell, but it’s small and ordinary.

All in all, the best bet is Saturday morning the 8th of August: glassy, clean, and a decent 4ft south swell. The Sunday the 16th afternoon is a promising long-range call, but don’t lock it in yet. Otherwise, it’s a lean run with plenty of flat or poor days in between.

Rusty.
