Hey, it’s Rusty. Let’s talk Shichirigahama. It’s a river break, inconsistent, so you have to pick your moments. Crowds can show up, but it’s usually manageable.
We start Tuesday morning the 7th with a clean offshore breeze out of the NE at 12 mph. Swell is 2–3 ft from the SSE with a 15-second period – moderate energy (287). Water temp is about 75°, right on average for the season. Nothing huge, but clean lines are on offer. Tuesday afternoon the swell pushes 3 ft with light cross-off wind, still good.
The best early call is Wednesday morning, July 8th. Swell jumps to 4–5 ft from the SSE, very long 16-second period pumping strong energy (1094), and a light cross-off breeze from the east at only 3 mph. That’s a sweet window for an intermediate session. Wednesday afternoon turns onshore and goes downhill.
Then it’s a brutal lull. From Thursday the 9th right through Monday the 21st – over 13 days – wind stays onshore and the swell drops to nearly nothing. Hardly a wave worth chasing. That’s the reality of an inconsistent setup.
But there’s a light at the end. Wednesday morning the 22nd shows glassy conditions, almost no wind, and a 4 ft S swell at 14 seconds with moderate energy (702). It’s a long way out, so take it with a grain of salt, but if it lines up it’ll be another clean morning.
Grab that Wednesday the 8th if you can.

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.
