The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Shichigahama area over the next couple of weeks.
To be honest, it's a pretty flat and quiet start. For the first week and a half, we're looking at hardly any real swell to speak of. The water temp is sitting at a warm 79°F, which is pretty much bang on average for this time of year, so that's nice for a paddle, but the waves just aren't there. There's a long stretch from the 20th right through to the 28th of July where it's all tiny dribbles under 1ft, and the combined wave energy is weak, barely cracking 30 (16-30). Nothing worth getting wet for.
Now, we finally start to see a pulse of energy building from the 28th of July onwards. The swell direction starts swinging around to the SSW, which is the optimum direction for Shichirigahama, a river break. The combined energy creeps up into the moderate range, hitting 180-241 by the morning of the 29th. That Wednesday morning, the 29th of July, offers the first glimmer of hope. We're looking at a 3ft SSW groundswell with a long period of 12 seconds, and the wind is glassy. That's clean conditions and a decent little pulse. The break is inconsistent though, so you'll need to be patient.
The real standout in this forecast, and the one I'd circle on your calendar, is the morning of Friday, the 31st of July. The swell bumps up to 4ft out of the SW with a period of 7 seconds, and the combined energy jumps to 285, which is moderate but solid for this spot. The wind is glassy again, and the forecast says "expect good surf conditions." That's the best we've seen. For a river break like Shichirigahama, that SSW-SW swell direction is ideal, and with glassy conditions, it'll be clean. Keep in mind it's an inconsistent spot, so the waits between sets might be a bit longer, but the quality should be there. Crowds are sometimes a factor here, so you might have some company.
After that, it drops back off quickly. The 1st of August sees the swell fade and the wind picks up, turning onshore, so get it while you can on the 31st.
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.
