Right, let’s have a look at what’s cooking around here. Honestly, for the next few days, you’re better off staying on the beach with a cold one. There is barely any energy in the water through Friday afternoon, with the combined swell energy sitting at just 34 (weak) on Friday morning and dropping even lower. We are looking at a big blank run here – nothing worth paddling out for until Tuesday, July 7th. That’s nearly four days of flat to close-to-nothing.
Alright, so the action finally kicks off on Tuesday morning, July 7th. Shichirigahama (Japan) is the one break to focus on this whole window. The swell picks up proper, with waves around 4ft coming from the SSE on a long 17-second period combined energy of 1092 (moderate). The wind is cross-offshore, clean, and it’s shaping up real nice. But the standout window is Tuesday afternoon: glassy conditions, 5ft SSE groundswell at 16 seconds, and that energy jumps to 1143. It’s going to be clean, lined up, and proper fun for an intermediate. This is the best you’ll get.
Come Wednesday, July 8th, the swell gets bigger, hitting 6ft in the morning and 7ft in the afternoon from the SSE, but the wind turns onshore and choppy, so the quality drops. That’s more for experienced surfers if you’re desperate, but the magic is gone. Thursday and Friday see it even bigger—over 7ft—but with poor onshore winds. It’s messy and big, not worth it for most.
Now, Saturday, July 11th morning brings a second chance. Glassy conditions again, with 6ft SSW swell at a very long 16 seconds. That’s powerful stuff—combined energy of 1571—but with that kind of period at a river mouth, it might wall up and be tricky to get into. It’s better for the more experienced crew. After that, the swell slowly fades through the following week, with winds mostly onshore or cross-onshore. The water temp is about 74°, which is pretty normal for this time of year, so no wetsuit drama.
So, to wrap it: Tuesday, July 7th is your day. Get on it early or afternoon. Saturday, July 11th morning is a solid backup if you can handle a bigger, longer-period groundswell. The rest is either flat, blown out, or too big for the average punter.

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.
