The Lowdown
Alright folks, Rusty here. Let's have a look at what Shichigahama's got cookin' for us over the next couple of weeks.
Straight up, it's a bit of a tease. We're looking at a whole lot of "poor surf conditions" with not much to get excited about for the first week, but there is a little light at the end if you're patient.
We get a tiny pulse on the 28th (Friday morning). It's only 4ft from the SW with a short 6 second period and cross-offshore wind at 6 mph. The combined energy is weak (127), so it's barely a blip. You might get a few crumbly ones, but don't expect much. That window closes fast as the wind goes glassy in the afternoon and the swell drops right off.
From the 29th of August through to the 4th of September, it's pretty much flat or blown out. The swell tries to build, but it's accompanied by strong onshores, hitting 25-35 mph from the SSW, making it a complete mess. By the 4th, we've got 7ft of short period slop, but with those winds, that's kite-surfing territory, not paddling.
Now, here is where it gets interesting for the patient surfer. On the 5th of September (Saturday), we finally get a break in the weather. The wind swings around to the NNE at 16 mph, giving us clean, offshore conditions. Swell is a modest 3ft from the south at 9 seconds, with moderate wave energy (219). It's not going to be epic, but after a week of nothing, clean lines on a 3ft wave sound pretty good.
Then, things get promising but a bit uncertain further out. On the 10th and 11th of September, we see another window. On the 10th (Thursday), we get an offshore wind again (NNE 13 mph) with a 3ft SSW swell at 9 seconds and moderate energy (167). Then on the 11th (Friday morning), it goes glassy with a 3ft S swell at 9 seconds. For a spot that's inconsistent, a morning with glassy conditions and some waist-high waves is about as good as it gets. Keep an eye on this one, but don't book the day off work just yet.
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.
