The Lowdown

Alright folks, Rusty here. Let’s look at what’s coming for the Sakawa River. Gotta be straight with you – this stretch is looking pretty grim for a long while. The first real window of surfable energy doesn't show up until Thursday morning, the 16th, and even then it’s a small, short-period swell. We’re looking at a massive gap of dead flat or poor conditions before that. It’s a tough start.

The Sakawa River only gets a tiny 3ft swell from the SSW on Thursday morning, July 16th, with a very short period of 5 seconds. That’s weak, weak energy (80). The one saving grace is glassy conditions, so it’ll be clean as a whistle for the small ripples. But honestly, it’s barely surfable, and only for the most desperate of floaters. The rest of that week and into the next is just a write-off – tiny, onshore, and messy.

You’ve got to wait until the 29th of July, Wednesday morning, to see something real. That’s a solid 4ft groundswell from the SE with a long 14-second period, and the energy is pumping – 813. The wind is light and cross-off, keeping it clean. This is a standout, but it’s a point-break style river mouth, so that long period could make it a bit straight and fast. Still, a proper wave is on the cards.

The absolute best of the whole run, and the one to circle, is Thursday morning, July 30th. That’s 8ft of SE swell with a very long 16-second period, and the energy is massive at 3444. The wind is glassy – SE at just 3mph. That’s the kind of setup that’ll have the river mouth handling some serious size. This is for experienced surfers only; over 8ft gets sketchy, but this is right in the expert wheelhouse. The water temp is about average for the time of year, nothing unusual.

Crowds are possible at the Sakawa River, so with a swell like that, expect a few locals out. The rest of the window is a drought. The Sakawa River is a fairly consistent spot, so this blank run is a bit of a bummer, but forecasts can change.

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.
