Alright, grab your board, this is Rusty.
Look, I’ve gotta be straight with you. We’ve got a 16-day window here for Shichirigahama, a river mouth break, and honestly, it’s a pretty grim stretch. The forecast is a real letdown. There’s very little surfable swell on the cards and most of the time the winds are just going to mess things up.
We start with Monday morning, July 13th. That’s the only real glimmer we get for a while. It’s small, with a 3ft SSW groundswell at a long 13 seconds. The energy is moderate (313), but the water temp is 76°, which is pretty much average for this time of year. The kicker is the wind: ENE at 3 mph and glassy. That’s going to give us clean, smooth conditions right off the bat. So if you can get out there Monday morning, that’s your best bet. After that, it’s a long dry spell.
For the rest of that week and into the next, from Monday afternoon all the way through to Saturday, July 25th, the swell just disappears. We’re looking at tiny 0.7ft to 2ft slop with short periods, and energy readings that are mostly in the teens and twenties – that’s weak stuff. The winds are constantly onshore, cross-onshore, or just wrong. It’s going to be blown out and choppy. You’d be wasting your time.
Now, there’s a little pulse towards the end of July. Sunday the 26th and Monday the 27th see a slight lift. The swell builds to about 3ft to 3ft from the SSE, with periods of 10 to 12 seconds. The wave energy climbs back into the moderate range (163 and 276). The winds early on Sunday and Monday morning are looking clean and offshore from the ENE and NNE. But the comments on the forecast say it’s "surfable waves but very ordinary conditions" or "marginal." It’s a small, weak offering. Monday morning has that fresh offshore wind at 18 mph, which will hold the faces up, but the swell is just too small to get excited about.
Honestly, if you’re desperate for a paddle, stick to Monday morning, July 13th. That’s the standout, tiny as it is. The rest of the window is a write-off. Don't expect much company on the 13th because the crowds are only "sometimes" a problem here anyway.

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.
