G’day, I’m Rusty. Let’s get into it.
Look, I’ll be straight with you – this 16-day window for Shichigahama is a real mixed bag, and honestly, there’s not a whole lot to get excited about. The first real chance you’ll have to paddle out is on Sunday, 13 July, but it’s a one-session wonder. The early morning is your only shot, and it’s actually a beauty, so that’s where I’d put my money.
The standout for the whole period is the early session on Monday, 13 July. The swell is a clean 3 ft from the SSW, with a long 13-second period – that’s proper groundswell energy, meaning the waves will have some shape and punch. The combined energy is moderate (313), and the wind is glassy from the SSE. That’s about as good as it gets for a river mouth break like Shichirigahama (Shichigahama). The water temp is about average for the time of year, nothing wild. You’ll get clean, lined-up waves, and the crowd is only a “sometimes” thing, so you might have a few friends out but nothing hectic. The swell direction (SSW) matches the optimum, so the break will be firing. Just keep in mind, this spot is inconsistent, so when it’s on, you don’t miss it.
After that Monday morning, it’s a long, dry stretch. From Monday afternoon all the way through to Saturday, 19 July, the conditions turn to rubbish – onshore winds, short-period junk, and poor surf quality. The energy drops off a cliff, with readings below 100 (weak) most days. There’s literally nothing to recommend.
The next little flicker of hope comes on Saturday, 18 July late morning. The swell is only 3 ft from the SE, with a 10-second period, and the combined energy is moderate (179). The wind goes offshore from the NE at 12 mph, which is clean. But it’s still only a “surfable” rating – not a standout. The wave quality is just ordinary. After that, it’s back to poor conditions, with the wind swinging onshore again and the swell staying tiny.
The second week, from 21 July onward, is a total write-off. The swell height barely touches 2 ft, the periods are short, and the wind is mostly onshore or cross. The combined energy is weak, often under 100. There’s nothing to chase. For a spot that’s already inconsistent, this kind of blank run is pretty normal for the area. I wouldn’t hold your breath.
So, to sum it up: set your alarm for Monday morning, 13 July, at Shichirigahama. That’s the one. The rest of the month is a waiting game.
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.
