Sakawa River Surf Forecast and Surf Report

Alright, let’s get into it.

Right off the bat, the Sakawa River isn’t really offering much for the first week or so. It’s a pretty bleak run from Wednesday the 9th through to the Thursday the 17th. There are a few days where the swell is just non-existent, down around 1ft to 2ft, and we’ve got weak energy readings in the 50s and 60s. That’s not surf, that’s just a lake. The wind is mostly cross or light cross-off, but with no swell to push around, it doesn’t matter. It’s a real flat spell. The water is sitting at 82°, which is a touch warmer than normal for this time of year, that’s a small comfort if you’re just going for a paddle.

We finally see a pulse of energy arrive late on Friday the 18th. The morning is still messy, but by the afternoon, the wind swings to a cross-off from the NNE and the swell jumps up to 3ft with a longer period of 15 seconds. That’s got some life to it. The energy number jumps up to 415, which is a start. It’s not big, but it’s clean.

Then Saturday the 19th is where things get interesting. The swell builds to 5ft, coming from the SSE with a 14-second period, and the energy is up around 1357 to 1635. That’s moderate to strong. The morning is the pick with a clean cross-off breeze. This is a river break, and that long period groundswell with that direction will be linking up nicely. This is looking like the first real standout.

Sunday the 20th is the big one though. We’ve got a proper groundswell pushing through. The morning shows 7ft from the south with a 16-second period, and the energy is a strong 2480. The wind is a light cross-off from the NNE. It’s clean, powerful, and organized. The afternoon gets even better with a glassy, 7ft southerly swell and a 15-second period. The energy is still strong at 1788. This is the best day on offer, no doubt.

Monday the 21st keeps the momentum, with the morning seeing 7ft from the south, a 16-second period, and energy at 2596. The cross-off wind is light. This is board-shortening territory. The afternoon gets a bit messier with a cross-shore wind and the swell swinging to the SSW, but the morning is the window.

Tuesday the 22nd is still solid, with 7ft from the SSW in the morning, but the afternoon is where I’d be. The wind goes glassy, and we still have a 6ft swell with 14 seconds of period. That’s excellent.

Now, for the caveat. This river break is handling a lot of size, but when it gets over 8ft, it can get tricky, and on the 23rd we’re seeing a solid 13ft southerly swell with a short 9-second period and a fresh 30 km/h cross-shore wind. That’s blown out and maxed out. That’s not for us; that looks more like a kiteboarding zone than a surf break. A messy, oversized, wind-blown river mouth isn't a fun paddle.

After that, on Thursday the 24th, it drops right back down again. The morning is glassy with a clean 3ft south swell, but the energy is dropping fast, and it just fades out from there.

So, to wrap it up. Look to Saturday the 19th for a taste, but the real standout is Sunday the 20th. Big, clean, long-period south groundswell with next to no wind. Monday morning is a close second. Get on it.

Rusty.
