The Lowdown
Alright, Rusty here, looking at the local surf for Shichigahama over the next couple of weeks. Gotta be straight with you—it’s looking pretty grim for a while. The whole stretch from Tuesday, July 14th, right through to Monday, July 27th, is a write-off for any kind of decent surf. We’re talking waves under 3 feet, often with onshore or cross-onshore winds, weak energy levels (often under 100), and just bad conditions. There are a few glassy moments here and there, like Thursday morning the 16th with a glassy surface and light airs, but the swell is tiny at 2ft and the period is a short 5 seconds, so it’s just not worth paddling out. Even the times it cleans up, like Saturday morning the 18th with clean conditions and a cross-off breeze, the wave size is barely 1ft. You’d be floating. It’s a tough run for a spot that’s a river mouth, fairly exposed to swell from the SSW, but right now the ocean isn’t giving us anything to work with. The crowds can show up here sometimes, but with this lack of surf, I doubt anyone’s wetting a line. The water temperature is about average for this time of year, so no surprises there.
Now, there is a light at the end of the tunnel, but you’ve got to be patient. Things start to look a little better on Tuesday, July 28th. The morning brings some clean waves at Shichirigahama (Japan) with a 2ft swell from the south, an 11-second period, and a nice cross-off wind from the northeast. The combined energy is moderate at 127, and the conditions are clean. It’s not a big swell, so it’s fine for all levels, and the longer period means better-shaped waves, though at a beach setup it might break a bit straight. The afternoon stays clean too with a cross-off breeze and similar size. This is the standout of the whole forecast—ordinary waves but clean and rideable. It’s the only time in the entire 16 days we get a score above zero. The wind stays cross-off again on Wednesday the 29th in the morning, but the swell drops back down to 2ft. So if you’re keen, make a move for Tuesday the 28th—that’s your window. Everything else is a flat spell.
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.
