The Lowdown
Alright, this is Rusty. Let's take a look at what's cooking for the Shichigahama area.
Right now, it's a desert. The first week or so is a total bust for any decent paddle surfing. You'll see a few tiny waves, but they're all junk with onshore winds; not worth waxing the board. On Thursday the 30th, the early morning is glassy, but with swell barely a ripple at 1ft from the SSW, there's just no push. That flat, poor run holds through the weekend and into the start of the new week.
Things start to get interesting around Monday the 3rd of August. The swell picks up, but it's a messy southeasterly push with a long period of 18 seconds. For Shichirigahama, a river mouth setup, that long-period groundswell can make the waves break too straight and dumpy. The winds are still messy too, so it's more of a "watch the forecast" than a "go now" day.
The real standout window is Tuesday the 4th through to Thursday the 6th. This is where the ocean fires up. The combined swell energy jumps into the strong range (1610 on Tuesday morning) and keeps climbing, hitting a massive 7659 on Wednesday afternoon. That's serious grunt. The SE swell is a good angle for this spot, and the key is the wind: Tuesday morning sees a moderate offshore breeze from the NE, keeping it clean. The waves will be 5ft to 6ft, which is a solid size for a good intermediate. By Wednesday, the swell is huge – 10ft to 12ft. That's expert territory only. The winds are still offshore or cross-off, so the faces will be clean, but you'll need to be on your game. The 18-second period means very long, powerful lines, but be aware at a river mouth, that long period can make things close out. Thursday morning keeps the size at 12ft with another fresh offshore, still firing.
If you're an experienced surfer, Wednesday the 5th and Thursday the 6th of August are the absolute peak, but it's big, mean, and for the brave only. For a more manageable size, Tuesday morning the 4th looks like the best bet for a strong session without getting pounded into the sand.
After that big pulse, it drops off quickly. By Saturday the 8th, the swell is back down to 4ft, but the wind goes glassy in the afternoon, so you might get a small, clean, fun session if you're desperate. Then it's back to flat, poor conditions for the rest of the forecast.
The water temp is a touch warmer than normal at 81°F.
So, to sum it up: a long, flat wait, then a short, powerful window of proper, heavy groundswell. Mid-week is the time to be out.
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.
