Right, let’s have a look at what’s coming up for the Sakawa River over the next couple of weeks. The first few days are pretty quiet—Friday the 3rd through to Sunday the 5th are a write-off. Tiny, weak swell and poor conditions mean you’re better off doing something else. Monday the 6th stays marginal, with a small bump in energy, but it’s not worth getting excited about.
Now, Tuesday the 7th is where things start to get interesting. We’ve got a solid groundswell starting to build from the SSE, around 4 ft in the morning, but the real highlight is Tuesday afternoon. The swell jumps to 6 ft with a very long 17-second period from the SSE, and the wind goes glassy. The combined energy is strong (1855), and the water temp is sitting at a normal 74 °F. This is the standout session for experienced surfers—clean, powerful lines, but at that size it’s probably too much for beginners. Expect it to be a bit peaky and straight at a river mouth, but the quality will be there for those who can handle it.
Wednesday the 8th holds similar size at 6 ft to 8 ft, but the wind gets a bit messy with cross-onshore conditions, knocking the quality down. Thursday the 9th and Friday the 10th stay big, with swell around 8 ft to 8 ft from the S, but again, the wind isn’t doing us any favours. This is proper expert territory—over 8 ft is big, and the cross-onshore chop will make it a battle. The energy is massive (over 3500), but it’s more of a grunt session than a smooth one.
Saturday the 11th morning offers another good window. Swell drops to a more manageable 6 ft from the SSW with a 15-second period, and it goes glassy. That’s a great call for experienced surfers again, with clean conditions and strong energy (1617). After that, the swell fades through the week, dropping below 3 ft by the 13th, and conditions go back to being poor or ordinary. From the 14th onwards, it’s mostly small and messy, with no real standouts.
So, the pick of the period is definitely Tuesday the 7th afternoon and Saturday the 11th morning. Both offer that rare combo of solid groundswell and glassy wind. Don’t sleep on them.

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.
