The Lowdown

Right, Rusty here. Let's cut through the noise and see what's cooking.

Don't get too excited for the next few days, it's flat and messy. We've got a slow burn until things finally turn on next week.

The main event is Monday the 7th of September. We're looking at a proper pulse of S swell hitting about 8ft, with a wave energy reading of 1257, and the wind is forecast to be dead glassy. That's a nice groundswell with a 10-second period, giving it some real push. For the Sakawa River, this is a solid window. The water's at 83°, which is a touch warmer than usual, so leave the rubber at home. Just a heads up, 8ft is solid, so this is one for the intermediates and above.

That glassy vibe hangs around into Tuesday the 8th for the morning session with a still robust 6ft of SSE swell, and a moderate energy of 853. That's another top-notch window.

Beyond the 9th, the swell drops off a cliff. We're into small, weak surf and unfriendly winds right through the second week. So your window is really that one-day hit from Monday the 7th through the morning of Tuesday the 9th. After that, expect a solid week of nothing worth paddling for.

Get on it when it arrives. This one's worth a little schedule shuffle.

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.
