The Lowdown
Alright, folks, Rusty here with the skinny on the next stretch for Shichigahama. Gotta be straight with you: the next week is going to be a real test of patience. We've got a whole lot of flat, weak surf on the menu, with the swell energy bottoming out in the 19 to 94 range through the 7th. The wind will blow offshore a few times, which is nice for the soul, but it's just grooming a flat ocean. Not worth paddling out for.
Then things get interesting. The 8th sees the energy meters start spinning fast, and by the afternoon, it's game on. The swell jumps to a solid 10ft from the SSE with a 12-second period, and we've got a clean offshore wind. This isn't for beginners, folks. This is a powerful, expert-only wave at a river mouth. This is the standout of the entire period. It stays big and clean through the morning of the 9th, with waves around 8ft and the wind still offshore. Plenty of power in the water, with energy readings in the thousands. For a spot like this, that long-period groundswell with offshore winds is about as good as it gets. Remember, this is for experienced surfers only.
After that, it just dies again. From the 10th through the 14th, it's back to small, weak, and mostly blown out. The energy drops right back down. You'll see a couple of clean, knee-high days with offshore winds, but at 1ft, they ain't worth the time. The water is warm, about 82°, which is a touch warmer than average for this time of year.
Looking ahead, there's a promising return to form around the 15th of September. Now, this is a long way off, so treat it with caution, but the models are hinting at another solid pulse of long-period SSE groundswell combined with light offshore winds. We could see waves in the 7-8ft range with a 15-second period. If that holds, it could be another proper session, but it's a waiting game to see if it firms up. The day after looks like it'll be wind-affected, and then it's back to small stuff.
So, to wrap it up: The window to get excited about is the afternoon of the 8th and the morning of the 9th. Big, clean, powerful swell. The 15th is another one to keep an eye on, but it's a long-range promise. Everything else is small, weak, and not worth getting worked up over.
Rusty, out.

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.
