The Lowdown
Alright folks, Rusty here. Gotta be straight with you—this isn't shaping up to be a classic run for Shichirigahama. We're looking at a long stretch of flatness before things finally get interesting, so patience is the name of the game.
The next several days are a write-off. We’re talking a full run of glassy mornings and small, weak windswell that just doesn't have the guts to stand up. The combined swell energy is stuck in the low double digits, barely cracking 49, and the period is a weak 7 seconds. That's just dribble, not surf. The water is sitting at a warm 81°, about average for the time of year, but you won't be needing a wetsuit for the paddling you'll be doing—which is none.
Thursday the 31st through to Sunday the 4th of August, the swell tries to build, but it's still small and messy. A few clean mornings with offshore breezes, but the waves are tiny and the energy is only moderate. It's not until Monday the 5th of August that we see a pulse of energy. The swell finally jumps to 6 ft, and the combined energy hits 1537, which is a solid kick. Tuesday morning the 6th of August looks *very* promising. The swell is a solid 6 ft from the SE, with a clean 17-second period. That's proper groundswell. The wind is offshore from the NE at 15 mph, which will keep the faces clean. This is the best bet in the early window, but it’s still a bit raw.
The real standout, the one you want to circle on the calendar, is Wednesday the 7th of August. The swell pumps up to 10 ft from the SSE, with a beefy 17-second period. The combined energy is a massive 4732. That's strong, powerful stuff. The wind is offshore from the NE, keeping it clean. This is expert territory. At 10 ft, it's way too big for beginners. But for the experienced crew, this is the session. The long period (17 seconds) means it will be a bit more walled up at the beach, but the river mouth can really focus that energy. Thursday the 8th looks similar, with 10 ft from the S, but the wind turns onshore in the afternoon, which will mess up the faces.
After that, the swell backs off through the weekend and into the next week. The second week of the forecast is all about small, fading leftovers. The run from the 9th of August onward is mostly flat or marginal, with weak energy and onshore winds. It's a quiet end to the window.
So, to sum it up: the first week is a flat spell. Your best bet is Tuesday morning, August 6th, for a clean, solid 6 ft groundswell. But the only true standout, the big one, is Wednesday, August 7th. That 10 ft, 17-second groundswell with offshore wind is the only day I'd call a proper standout. Get on it.
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.
