The Lowdown
Righto, let’s have a look at what’s on the cards for the Shichigahama region. To be straight with you, the next week or so is pretty grim. We’ve got a long stretch of tiny, weak swell and mostly poor conditions. The first real glimmer of anything worthwhile doesn’t show up until Monday the 7th of September, and even then, it’s only just surfable. The energy is pretty weak at that point, with combined swell energy bumping up to around 118 (moderate), but the wave heights are still only 2 ft and the conditions are described as very ordinary. The water temperature is about average for this time of year, so no shock there. It’s not until Wednesday the 9th that we start to see a bit more size, with swell climbing to 4 ft from the SSE. The combined energy jumps into the moderate range (336-445), and the wind is clean offshore from the NNE to NE, which is a big plus. Still, the forecasters are calling it marginal, so don’t expect perfection. Thursday the 10th offers similar conditions, with 5 ft SSE swell and a solid 750 (strong) energy reading, but again, it’s only a marginal call. The wind is still offshore in the morning, so it could be worth a look for the more dedicated among you.
Then things get messy. Friday the 11th and Saturday the 12th see a big jump in swell height, up to 6 ft and 8 ft from the SSE and S, with combined energy spiking into the strong range (1361 and 1034). But the wind is onshore and howling – near gale force on Friday – blowing it all out. This is a poor setup for paddle surfing, but if you’re into kite surfing, the combination of strong wind and solid swell could be more interesting. The swell is also on the short period side (10-11 seconds), so it’s not going to be the best shape.
The real standout, and the only day I’d get genuinely excited about, is Tuesday the 15th of September. Now we’re talking. The forecast shows a 13 ft swell from the SSE with a period of 13 seconds, which is a proper groundswell with plenty of energy (combined energy of 5491 – very strong). The wind is a moderate offshore breeze from the NE, so the waves should be clean and well-shaped. That size is only for experienced surfers, mind you – over 8 ft is expert territory. Also, with that long period, the sets will be more powerful and have longer gaps between them, which can make paddling out a bit easier. But for a beach break like Shichigahama, that long period can sometimes make the waves break too straight, so it’s worth keeping in mind. Still, this is the best option in the entire 16-day window, hands down. Just remember, it’s a long way out, so treat it as a promising but not locked-in call.

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.
