The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line.
To be honest, the next week and a half are looking pretty flat. We’ve got a long stretch of tiny, weak swell with mostly cross-onshore winds. The Sakawa River is going to be a no-go for paddle surfing until the very end of the month. The water temp is about average for the time of year, so nothing special there.
The first real sign of life shows up on the morning of Monday, July 27th. The swell bumps up to 3ft from the SSE with a 12-second period, and the combined energy is moderate. The wind is light and cross-shore, so it’s not perfect but it’s rideable. This is marginal, but it’s the first time we’ve seen anything worth paddling out for.
The best on offer looks to be the morning of Tuesday, July 28th. We’ll see a 5ft S swell, with a 13-second period giving it some decent push. The combined energy is strong. The wind is light and cross-shore, so the river mouth could clean up nicely. This is a bit much for beginners, but for intermediate surfers, it’s the standout window. The afternoon picks up a bit more size – 5ft – but the wind swings cross-onshore and gets choppy, so mornings are the call.
After that, the swell hangs around for Wednesday, July 29th, with 4ft SSW swell and a 13-second period, combined energy in the moderate range. Again, light cross-shore winds in the morning offer the best chance for a wave. The swell fades by Thursday and Friday, leaving us with smaller, weaker leftovers.
So, if you’re keen, pencil in the 28th morning. That’s the one to aim for.
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.
