The Lowdown

Alright, grab your waders if you’ve got ’em, because the next 16 days at Shichigahama are looking pretty grim, to be honest.

Look, I’m not gonna sugarcoat it – this stretch is a tough one for us paddle surfers. The swell is tiny for the most part, barely cracking 2ft to 2ft for the first two weeks, and the overall energy in the water is weak, sitting under 100 most days, with only a few touches of moderate energy around 151 or 154. The waves that do show up are just not holding any power, and the southeast to south winds are often onshore or cross, messing up what little shape there is. We’re looking at a big dry spell, with no real recommendations from Sunday, August 9th, all the way through to around Friday, August 22nd.

There is one faint glimmer of hope right at the tail end. On Saturday, August 22nd, in the afternoon, we finally see a bump. The swell jumps to 4ft from the south with a proper 12-second period, and the energy rockets up to 351 (very strong). That’s the best looking window we’ve got. Even better, the wind is gentle offshore from the northeast, which should clean things right up. This is probably the one standout, but it’s two weeks out, so treat it as promising but not a sure thing.

For that afternoon on the 22nd, I’d point you to the river mouth at Shichirigahama. It’s a bit inconsistent and only fairly exposed, but when that long-period south swell hits, the river mouth setup can focus it nicely. Just keep in mind, with that period over 11 seconds, it might wall up a bit at the beach and be better for the more experienced crew. The water temp is sitting at a normal 81°F for this time of year, so no shocks there.

Other than that, it’s a bleak run. Many mornings have offshore winds, but with waves under 2ft and short periods, there’s just no push. For the first two weeks, this is more interesting for the kiteboarders than anyone with a paddle.

Stay patient, keep an eye on that 22nd, and hopefully the models hold.

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.

Shichigahama is 6 km (4 miles) from the city of Chigasaki. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Chigasaki. Chigasaki has rooms for a wide range of budgets as well as car hire and transport links.
