Alright, Rusty here. Let’s have a look at what’s cooking for the Sakawa River area.
Right now, things are flat and pretty ordinary. We’re looking at a few days of tiny surf through to the 5th of July, with onshore winds and messy conditions. Honestly, there’s nothing worth paddling out for until Monday the 6th.
The first real flicker of hope shows up Monday afternoon on the 6th at the Sakawa River. You’ve got a 3ft ESE groundswell with a very long 14-second period and glassy winds. The combined swell energy is moderate at 524. The river mouth should offer some clean, slow peelers with such a long period, but don't expect a huge amount of push. It’s a nice little breather after the flat weekend.
Things start to ramp up properly from Tuesday the 7th. Tuesday morning sees a 4ft SSE groundswell kicking in, period at a very long 16-seconds, with a light cross-offshore NNE breeze. That’s clean, and the energy is getting serious at 920. Nice. Tuesday afternoon pushes up to 6ft SE swell at the same long period, but the wind picks up to a moderate breeze. Still clean, but with over 2,000 in combined swell energy, this is proper. Keep in mind, over 5ft means it's not for beginners here.
Wednesday the 8th stays solid with a 6ft SSE swell and 16-second period in the morning, and then a 8ft SSE swell by the afternoon. That afternoon is pushing into expert territory at 8ft, with light cross-onshore wind. The combined energy is huge, around 2,934, so plenty of power. The setup at a river mouth might handle this long period swell better than a beach break, but keep your wits about you.
Thursday the 9th and Friday the 10th keep the size up, with Friday morning peaking at 8ft S swell at a very long 17-second period. The wind is light cross-onshore, so there’ll be some texture on the face, but the energy is massive at 4,036. This is strictly for the experienced crew.
By Saturday the 11th, the swell starts to dip a little, still in the 8ft range but the wind becomes onshore, so quality slips. After that, the surf steadily fades through the following week. By the 12th and 13th, we’re back below 5ft and the winds are messy. From the 14th onward, it’s mostly tiny waves or flat spells with occasional glassy moments, but nothing that’ll get your heart racing.
Overall, the standout window is Tuesday the 7th through Friday the 10th. The best bet for clean, powerful waves with manageable winds is Tuesday morning – that 4ft SSE swell with that long period and clean offshore breeze is where it’s at for intermediate surfers wanting a taste of the juice. For the big guns, Friday morning the 10th is the biggest and longest-period swell of the run, but expect crowds because it's a river break and the conditions are average.
Water temp is 74°, which is about normal for the time of year.

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.
