Right. Gotta be honest with ya. The first few days here are flat. No meat on the bone at all. Friday the 3rd through Sunday the 5th is just no-go. Small, weak, messy. Don’t bother.
Things start to get interesting from Monday the 6th. Early Monday we see a 3ft swell from the ESE with that clean cross-offshore wind, but the period’s short and the combined energy is only moderate (214). It’s rideable, but nothing to write home about. Tuesday the 7th is where it gets weird. Tuesday morning has a 3ft swell with a very long 17-second period from the SSE. The energy number jumps to 924 (moderate-strong), and the wave comment says marginal, but that long period means those waves will have serious push. Keep an eye on it, but those long-period swells can get a bit straight at a river mouth.
Wednesday the 8th afternoon is the first real standout. Sakawa River cleans right up with glassy conditions and a solid 7ft swell from the SSE with a 16-second period. The combined energy is huge at 2513 (very strong). That’s big, powerful, and clean water. But look – over 8ft is expert territory, and at 7ft it’s still going to be a handful for anyone but solid intermediate or above. Definitely not a beginner day. Crowds are possible here, especially when it's this good.
Thursday the 9th is still solid with 7ft swell from the SSE in the morning, but the wind turns cross-onshore, so it won't be as clean. Friday the 10th holds in the 8ft range from the S/SSW, again with that cross-onshore wind, so it’ll be lumpy but still powerful.
Then Saturday the 11th morning is another glassy standout. 6ft from the SSW, 16-second period, combined energy of 1860 (strong). That’s excellent, clean conditions for experienced surfers again. The water temperature is about 74°, which is just a touch cooler than average for July, so not a big deal.
The swell then slowly fades from Sunday the 12th onward. By Monday the 13th it’s back down to 2ft and poor, and from Tuesday the 14th right through to the end of the forecast window on Saturday the 18th, it’s all small, weak, and not worth paddling out for. That’s a solid four-day gap of nothing.
So, to wrap it up: the best windows are Wednesday the 8th afternoon (7ft, glassy, very strong energy) and Saturday the 11th morning (6ft, glassy, strong energy). Both are for experienced surfers.

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.
