G’day, Rusty here. We’ve got a bit of a mixed bag coming up for Shichigahama over the next couple of weeks. The window kicks off with some solid swell early on, but the wind is messy for the most part. There are a few windows where things clean up, worth keeping an eye on.

The first real opportunity is Thursday the 9th in the morning. Swell’s coming from the south at 5ft with a 14-second period, which gives it a bit of push. The water sits at 75°, pretty much average for this time of year. The wind is onshore though, blowing from the south at 6 mph, so it’s a bit lumpy. The combined energy is moderate (937). Not perfect, but it’s the first surf on offer.

Friday the 10th morning sees the swell bump up to 6ft from the south, with a 15-second period – that’s proper groundswell energy. The wind is still onshore from the south at 9 mph, so it’s gonna be a bit ragged. Combined energy is strong (1410). The wave heights are getting into intermediate territory, but the onshore wind is holding it back.

The standout peaks on Saturday the 11th morning. Swell hits 7ft from the SSW, with a 17-second period – that’s very long period groundswell, meaning it’ll have plenty of punch and long lulls between sets. The wind is still onshore from the south at 9 mph, so it’s not clean. Combined energy is very strong (2605). This is only for experienced surfers; the size and period will make it a handful at the river mouth. The afternoon gets messy with the wind picking up to 22 mph.

Sunday the 12th morning is a bit of a saving grace. The swell drops to 6ft from the SSW, still a 16-second period, but the wind is light at 6 mph from the same direction, so it’s onshore but light. Combined energy is still strong (1694). The rain might put a dampener on things, but the surf is rideable for intermediates.

After that, the swell fades fast. Monday the 13th morning is the only clean session in the next run. Swell is small at 3ft from the SSW, 13-second period, and the wind is offshore from the NNE at 3 mph. Combined energy is weak (287). It’s clean and glassy, but tiny. A good session for a longboard or a foiler.

There’s a big gap of poor conditions from Tuesday the 14th all the way through to Sunday the 20th. Mostly small, weak swell and onshore winds. Not worth paddling out.

The next real light at the end of the tunnel is Tuesday the 22nd morning. Swell picks up to 5ft from the south, 12-second period, and the wind goes glassy. Combined energy is moderate (747). That’s about as good as it gets in this run – clean, glassy waves, waist to shoulder high. A proper dawny.

Then Friday the 24th morning has a small, clean option with 3ft from the south, 12-second period, and a cross-offshore wind from the ENE at 6 mph. Combined energy is weak (284). It’s clean, but small.

Overall, the best bet is Tuesday the 22nd morning for the cleanest conditions. Saturday the 11th morning has the most size and power, but it’s only for the experienced crew. Keep an eye on the forecasts.

Rusty.

Information about the Shichirigahama Surf forecast

The above surf forecast table for Shichirigahama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shichirigahama can be found by selecting the local surf guide option on the grey menu. Our Shichirigahama 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 (Shichirigahama) 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 Shichirigahama 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.
