The Lowdown
G’day, Rusty here, with the lowdown on the Sakawa River stretch for the next couple of weeks. Fair warning, it’s a slow start. We’re looking at a long, drawn-out period of tiny, weak, and messy conditions before anything worth paddling for shows up. The first real glimmer of hope doesn’t come for a while, so keep your expectations in check.
Right now, and for most of the next week and a half, it’s pretty bleak. The surf is small, under 2 ft, with periods all over the shop and the combined energy is weak, barely cracking 50 to 80 (units of energy). The wind is mostly light or glassy at times, which is nice, but there’s just no swell to work with. The water is sitting at 76°F, which is a bit colder than normal for this time of year, but not freakish. Nothing’s worth a look until way down the track.
There’s a real gap in decent surf from the start of the forecast all the way through to the very end of the month. We’re talking over two weeks of poor surf and marginal conditions. The only flicker of something bigger comes right at the end. On the 29th of July, Wednesday morning, the swell starts to bump up to around 5 ft from the S, with a period of 13 seconds. The combined energy jumps to 914 (units), which is finally a solid, moderate push. The wind is glassy and offshore from the SSE, so it could be clean. However, it’s still flagged as marginal, and the tide might be iffy. It’s a long-range call, so don’t book your flights yet, but it’s the only real standout in the whole window.
The 30th of July, Thursday morning, has a similar story: 4 ft from the ESE with a very long 15-second period, and energy at 1021 (units). The wind is still light and offshore, but that long period at a river mouth can be a bit tricky, making the waves too straight. Still, if you’re a patient surfer, it’s the best you’ll get.
If you’re desperate for a paddle, the 28th of July has some moderate energy (217–329 units) but the swell is only 3 ft and the wind is cross-onshore, so it’s not great. Honestly, for most of this run, the setup looks more interesting for a kite surfer than a paddle surfer, with small, choppy waves and cross-shore winds.
Stay patient, and keep an eye on that last week of July. It’s promising, but not certain.

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.
