The Lowdown

Alright folks, Rusty here. Let’s break down what Sakawa River has cooking for the next couple of weeks.

We’ve got a real slow start. From Monday the 27th all the way through to Saturday the 1st of August, it’s pretty much flat. The swell is tiny, mostly around 1ft to 2ft, with combined energy readings mostly below 100, just a little bump to 131 on Tuesday morning. The wind is all over the place—either cross-on or glassy—but with waves that small, it’s barely worth getting wet. You might score a glassy moment on Monday afternoon or Wednesday morning, but honestly, it’s “surfable but very ordinary” at best. Water temp is about 82°F, a touch warmer than normal for this time of year. If you just want a float, go for it, but don’t expect any waves.

Then Sunday the 2nd of August, things start to wake up. A proper groundswell shows up from the ESE with a 15-second period—that’s long-period energy, ideal for a river mouth setup. The swell bumps to about 3ft by the afternoon, and the combined energy hits 390, so there’s finally some push. Wind is light onshore, still a bit marginal, but keep an eye on it.

Now the real gold is Monday the 3rd through Thursday the 6th of August. Monday afternoon is the pick of the run. Swell hits 5ft from the ESE, period 16 seconds, and the energy is cranking at 1312. Wind goes cross-off from the NNE, so those waves are going to be clean and lined up. This is your best paddle session, no doubt. Water’s still that warm 82°F.

Tuesday the 4th gets bigger—7ft to 7ft—but the wind turns more cross-on, so it’s not as clean. Still, with that 17-second period and energy in the 2000-2800 range, it’s worth a look if you’re intermediate and up. By Wednesday the 5th morning, the swell is 8ft from the ESE, period 16 seconds, and it’s glassy—dead calm. That’s excellent, but it’s expert territory at that size. Thursday the 6th gets even bigger, with 10ft swell and energy over 3800, glassy in the morning. That’s for the experienced crew only.

From Friday the 7th onward, it’s just too big for Sakawa. We’re talking 13ft to 28ft swells with energy readings in the tens of thousands—that’s massive, raw power. Wind is light and glassy at times, but the forecast says it’s too big for this break. Saturday the 8th with 28ft swell and 75329 energy—that’s enormous. Sunday the 9th starts to drop back, but still 13ft in the morning.

After that, it fades through Monday the 10th and Tuesday the 11th, dropping to around 8ft then 3ft, with the period coming down too. By Tuesday afternoon, the wind is up to 12 mph from the SSW and choppy, so we’re back to poor conditions.

Bottom line: The only real standout is Monday the 3rd of August afternoon—5ft ESE swell, 16-second period, clean cross-off wind, and strong energy. That’s your best bet for a proper session. Wednesday the 5th morning is also a cracker if you’re experienced and want glassy, big groundswell. Everything before the 2nd of August is basically flat, and after the 7th it’s too big for this spot. Get it while it’s good.

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.
