Alright, Rusty here. Let’s have a look at what’s cooking for Shichirigahama (Japan). It’s a river mouth setup, and we’ve got a real mixed bag ahead.
The week starts off with some promise. Tuesday afternoon the 7th sees a clean 0.9m SSE swell with a very long 15-second period and light cross-offshore breeze. The water temp is sitting at 23.9°, which is about average for this time of year—nothing unusual there. The combined swell energy is moderate at 447. It’s not massive, but it’s clean and fun for a rippable afternoon session. This is the best we’ll see for a few days.
Wednesday morning the 8th gets even better: 1.4m from the SSE, a massive 16-second period, and a slight offshore breeze. The energy jumps to 1094, so there’s some proper grunt. This is a standout window for the confident surfer—long-period groundswell like that will draw nice lines along the river mouth, just watch for lulls between sets. Afternoon gets blown out by onshore wind.
From Thursday the 9th onward, it’s a tough stretch. The wind swings onshore and stays there for days. The swell hangs around 1.4m to 1.9m through Friday and Saturday, but with strong onshores (up to 35 km/h on Saturday the 11th), it’s messy. Sunday morning the 12th is still onshore and only 1.6m. By Monday the 13th the surf fades fast, dropping to under 1m, and the conditions stay poor for more than a week.
There’s a near-week-long gap from around the 13th through to the 15th of July where it’s just flat or tiny junk. Wednesday the 15th shows a spike back to 1.5m SSE with long period, but the onshore wind is back, so no quality. After that it’s all small—0.2m to 0.7m—and mostly blown out or cross-shore. Even that slight lift on the 15th isn’t worth paddling out for.
Overall, you’ve got one true highlight: Wednesday morning the 8th. Tuesday the 7th afternoon is a solid warm-up. After that, put the board away until the forecasts change.

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.
