The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Shichirigahama.
Right now, the waves are pretty gutless. The opening of this outlook, Sunday the 23rd of August, we're looking at a weak 1ft SSW swell with a combined energy of just (36). It's a bit of a let-down, but the wind is a cross-offshore from the NE at 9 mph, so it's clean. The next few days are a write-off for any decent surfing. Monday the 24th sees a small bump in size but onshore winds and a combined energy of (399) still isn't enough to make it worthwhile, and by Monday afternoon the onshore wind is up to 16 mph. This pattern of onshore, messy wind and weak swell dominates right through until Thursday the 27th, with combined energy figures fluctuating but never delivering the goods.
There's a real blank run here from Sunday afternoon all the way through to the end of the week. It's pretty grim, to be honest.
Now, we finally get a little window of hope on Friday the 28th of August. The morning brings a glassy 2ft S swell (105 combined energy) with a clean NNE offshore breeze at 9 mph. The waves are small, but the conditions are right. The afternoon session is even better – glassy conditions with 3ft S swell (122 combined energy) and a slight air from the NNW. The period is only 9 seconds, so it's windswell, but for the size, it'll be clean. This is the best the outlook has to offer for the first week.
Saturday the 29th has a similar sized swell (2ft, 103 combined energy) but with cross-shore winds. Saturday afternoon sees the offshore wind return from the NNE at 12 mph, cleaning up a 2ft S swell (102 combined energy). Sunday the 30th and Monday the 31st of August are back to tiny, weak surf, though mostly clean.
Looking into the second week, the energy picks up a touch but it’s not a game-changer. Wednesday the 2nd of September shows a 2ft SSW swell (214 combined energy) with clean conditions in the morning, and by the afternoon it's a bit bigger at 3ft (271 combined energy) but with a cross-onshore breeze. Friday the 4th of September is the most promising of this later period. The morning has a 4ft S swell (540 combined energy) with a fresh NNE offshore breeze at 19 mph, but the real standout is the afternoon. Expect 4ft S swell (549 combined energy) with a solid NNE offshore wind at 16 mph. It’s the best quality forecast of the whole 16 days, but it's a long way out. Saturday the 5th of September also has potential with an offshore wind and a 3ft SSE swell (395 combined energy) in the afternoon.
Overall, keep your expectations in check. The Friday the 28th of August afternoon window is the closest real opportunity for a clean, small-wave session. The Friday the 4th of September afternoon holds the most promise for the future, but that's a long-range call.
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.
