The Lowdown
Alright, grab your board and let’s have a look at what’s on the menu for Shichigahama over the next couple of weeks. I’m not gonna lie, it’s a real mixed bag, and for a lot of the window, we’re looking at a pretty flat, frustrating stretch. The first real taste of anything comes on the morning of Sunday the 9th, but it’s a small one—just 2.3ft of SSW swell with a 10-second period. The energy’s weak at 151, so we're talking about small, clean little rollers. The wind is glassy, which is a huge plus, so if you’re desperate, it’ll be a fun, mellow session, but it’s not going to set the world on fire.
From there, it really goes quiet. There’s a long stretch from Sunday afternoon all the way through the week and into the next weekend where the swell just fades. We’re talking 1.6ft and smaller. There are some offshore winds in there, particularly on the 12th, 13th, and 14th, which will keep the surface clean, but there just isn’t any power behind it. The combined energy drops to under 100, often in the 50s and 60s, so it’s not really worth getting too excited about. It’s just small and weak.
Now, the one that stands out, and I mean *really* stands out, is Thursday the 20th. The morning window is the pick of the entire forecast. We’ve got 3.9ft of S swell, with the energy jumping to 304, which is a solid, moderate pulse. The wind is light and cross-offshore from the ENE, so it’s going to be glassy and clean. This is the one proper surfable window we get. The afternoon sees the swell bump up to 5.2ft, but the wind swings onshore from the S, which will chop it up and make it a mess. So if you can, hit it in the morning. The break is a river-mouth setup, best with a SSW direction, and this is coming from the S, so it’s not a perfect match, but it’ll still have some push. It’s a spot that is inconsistent, so when it does get a pulse like this, it’s worth the effort. Crowds are sometimes an issue here, so you might have some company.
After that, the swell backs off again. The 21st still has some energy around 162 from a S swell, but the wind is cross-offshore, which is okay. It’s not big, but it might be a bit more manageable than the 20th. Morning of the 23rd brings some long-period swell at 17 seconds, but it’s tiny at 1.3ft, so it’s not going to do much, even if the offshore wind is there. The long period is interesting, but with that little height, it’s just a tease.
So, the long and short of it is: there’s a whole lot of nothing for most of the next two weeks. The one true standout is the morning of the 20th. Make a plan for that one. The conditions will be clean, the swell will have some size, and it’ll beat anything else we’ve seen. It’s not for beginners at that size, but it’s not a monster either. For the rest, it’s a waiting game.

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.
