The Lowdown
Alright folks, Rusty here. Let's have a chat about what's on the cards for Shichirigahama over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week and a half is a write-off. We’re looking at a long, dry spell of no surf worth paddling out for from Friday the 17th of July all the way through to Sunday the 26th of July. The swell is tiny, mostly under 1 foot, and what little energy is there is getting chopped up by onshore winds. The combined energy readings are all in the weak double digits (16-52), so there's just nothing in the water. It’s going to be a frustrating stretch for a surfer, but the good news is that a few breaks around here are fairly consistent, so this kind of blank run is a bit of an anomaly. It can’t stay this poor for long.
The turnaround starts to show on Monday the 27th of July. The swell finally makes an appearance out of the S, building to 5 ft by the morning. The period is a very long 16 seconds, which is proper groundswell energy – we’re talking a combined energy of 2112. That’s a lot of power. Now, this is a river break, and a long-period swell like that is prone to breaking a bit straight on a beach, so it won't be world-class, but it's a major step up. The morning wind is light onshore from the SSW, so it’s surfable, but not glassy. The afternoon gets a bit stronger onshore, making it choppy, so the morning is your window.
The real standout, and the one you want to circle on your calendar, is the morning of Friday the 31st of July. We’ve got a solid 8 ft SSW swell pushing in, with a short 8-second period and a combined energy of 787. The wind is light and off the land from the ENE, keeping the surface clean. For a spot that’s been flat for over a week, this is a proper gift. The water temp is sitting at about 77°, which is pretty much average for the time of year, so no surprises there. Just be aware that 8 ft is getting into expert territory, and with it being a river break, the crowds are sometimes an issue. If you’ve got the skills, this is the one to go for.
The tail end of the forecast on the 1st of August sees the swell drop back down to under 3 ft with onshore winds, so that Friday the 31st is your best bet. Keep in mind, it's a long way out, so the forecast could change, but right now, that’s the one that’s got my attention.
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.
