Alright folks, Rusty here. Let's have a look at what's coming down the line at the Sakawa River.
This is a bit of a slow burner. We're looking at a gap right from the start. Sunday the 5th and Monday the 6th are pretty much a write-off with tiny, weak swell and poor conditions. Tuesday the 7th is where things start to get a little interesting, but we're still in marginal territory. The real interest kicks off from Saturday the 11th, but there's a long stretch of nothing after that, with the surf fading out completely from Monday the 13th right through to the end of the outlook on the 20th. A solid week-plus of flatness.
Saturday the 11th is your standout. The morning is the clear pick. We'll see a solid 7 ft swell coming from the SSW, and here's the kicker – it's glassy. Dead calm, no wind. That's a rare treat and it's going to make for some clean, peeling lines. The combined swell energy is pumping at 2429, so there's plenty of push. This is a proper groundswell with a 17-second period, and at a river mouth, that long period should wrap in nicely, giving you some nice, shapely waves with long gaps between sets. Be aware, that 7 ft is pushing into the "experts only" territory, so if you're not confident on a bigger board, maybe give it a miss. The SSW direction isn't exactly the optimum SE, but with that swell size and glassy conditions, it'll still be firing.
Tuesday the 7th afternoon is a close second. We've got a 6 ft SSW swell with a 16-second period and a cross-offshore breeze from the NNE at 12 mph. The energy is a strong 1559, but the air is a bit lumpy with a moderate breeze, so it won't be as perfect as Saturday morning. Still, clean surf for intermediate guys.
Sunday the 12th morning also looks worth a paddle, with 4 ft and those glassy conditions again, but the energy drops to 633, so it's a much smaller, mellower session.
For the rest of the week, the swell just drops right off. The river mouth will be flat, with nothing but tiny wind ripples. There's no energy to speak of, and the winds are messy. It's a real bummer after that Saturday blast. That's just the way it goes sometimes. Keep an eye on the forecasts though, things can change.
Rusty.

Information about the Sakawa River Surf forecast
The above surf forecast table for Sakawa River provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sakawa River can be found by selecting the local surf guide option on the grey menu. Our Sakawa River surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Sakawa River) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Sakawa River may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Sakawa River is 2 km (1 miles) from Odawara. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Odawara. Odawara has rooms for a wide range of budgets as well as car hire and transport links.
