Table - best surf conditions forecast for Sakawa River over the next 16 days.
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for us at the Sakawa River. It's a bit of a mixed bag, so let's get into it.
The truth is, this forecast starts off with a pretty flat spell. We've got a long wait on our hands, with very little doing for the first week or so. The numbers just aren't there for a decent paddle, with tiny, weak swell and poor conditions. That’s a good stretch to get the boards fixed or the fishing gear out. Don't hold your breath.
We finally see a pulse of life showing up towards the end of next week. The real standout, the one to circle on your calendar, is Thursday, 23 July. The Sakawa River is looking at a solid 8ft of southerly groundswell. That's proper energy, with a combined energy reading of 2590, and it's got a long 15-second period pushing in from the SSE. The wind is set to be a clean cross-offshore breeze from the NNE, which should groom the face nicely. This one will be for the experienced crew though – that's big, powerful water for a river mouth. The crowds might be out given the quality, but it looks worth the fight.
Leading into that, Wednesday, 22 July late arvo sees stirrings with a 3ft SE swell, but it’s nothing to get excited about. Friday Morning, 24 July will have a clean, offshore breeze from the NNW on a smaller 4ft SSE swell, making for some decent, cleaner walls after that big day.
After the main event, Saturday the 25th has a dropping swell around 6ft from the SSE, but the wind swings cross-off in the morning keeping things clean. By Sunday, 26 July, the surf settles to a glassy 6ft SSW swell – light offshores making for a beautiful morning session to wrap up the run. Enjoy it.
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.
