Hey, Rusty here again, same spot but in feet and miles per hour. Sakawa River is your local river mouth, and the next two weeks have a bit of a slow start then a solid window. Tuesday 7th July morning gives you 3ft of SSE swell with a 15s period, but the wind’s cross from the NE at 9 mph, energy just 631 – not much happening.
From Wednesday 8th July morning you get into the good stuff: 4–5ft of SE swell with a 14s period, energy 1515 – decent power. Wind is light ESE at 3 mph, cross-on but hardly noticeable. That long period groundswell works a treat at a river mouth. Crowds are possible but it’s fairly consistent. Thursday 9th July morning brings 5–6ft from the S, 14s, energy 1618. Still nice.
Friday 10th July morning is the standout: 7ft from the S, 15s period, energy 1893. Wind is SSE at 6 mph – light cross-on. Saturday 11th July morning is almost as good: 6–7ft from the SSW, 17s period, energy 2347 – very long period stuff that’ll wrap deep into the river. Light cross-on wind again. Both mornings are your best calls.
After that, Sunday 12th drops to 4ft and it’s downhill. Monday 13th through Sunday 20th July is mostly flat – 1ft to 3ft – with poor conditions and low energy. A long dry spell.
Then on Monday 21st and Tuesday 22nd July the wind shifts to cross-offshore from the NNE at 12 mph, making for clean waves. Tuesday morning has 5ft of ESE swell with a 12s period, energy 704 – not a total bust but the direction is off. Worth a look if you’re keen.
So lock in Friday 10th and Saturday 11th July mornings. That long period groundswell at the river will give you great shape, and the light wind keeps it glassy. When it’s over 5ft it’s for intermediate to advanced surfers only. Go get it.

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.
