The Lowdown

Righto, let’s take a look at Shichigahama, from now right through the next 16 days. It’s a bit of a slow burn, but don’t walk away just yet.

Right out of the gate, from Tuesday morning all the way through to Monday the 3rd of August, it’s mostly flat or tiny. We’re talking ankle-snappers with next to no energy. The combined swell energy is mostly below 100 for days on end – really weak. The water temp is sitting about normal for the time of year, nothing to write home about. The wind is glassy and calm some mornings, which is a tease, but there’s just nothing to surf.

Then, things start to stir. Tuesday the 4th of August is the first proper glimmer. There’s a southeast groundswell building. On Tuesday morning, the swell is 4ft from the SE, period at a very long 18 seconds. That’s got proper energy behind it (combined energy of 791), and the wind holds clean and cross-offshore. That’s the standout window. Shichigahama is a river mouth, so a long-period groundswell like that will peel nicely along the bank, giving you longer, more lined-up walls. The break is rated as inconsistent though, so treat those sets as the main event when they come.

It gets bigger from there, but the quality takes a hit. Wednesday the 5th sees the swell jump to 8ft in the morning and 10ft in the afternoon from the SE, period still bang on 18 seconds. Wind is offshore from the NNE in the morning – fresh, clean, and howling. This is expert territory. The combined energy is massive (4304 in the morning, 5707 in the afternoon). This is not for beginners; it’s big, powerful groundswell. A river break like this will handle it, but you need your wits about you.

Thursday the 6th of August is even bigger – 13ft from the SSE – but the wind turns cross-shore, introducing a chop. The energy is off the charts (8461 in the morning), but it’s a bit of a beast and less user-friendly.

From Friday the 7th onward, the wind goes onshore or cross-onshore and the whole thing turns into a messy, choppy wall of water. The swell drops but the conditions are poor for paddle surfing. If you’re into kites, those windy days with 10ft plus might be your thing, but for a surfer, we’re done by then.

The best bet? The morning of Tuesday the 4th of August for a clean, long-period southeast swell at 4ft. It’s not huge, but it’s the cleanest, most lined-up option in the whole run. After that, it’s for the big-wave crew only on Wednesday morning.

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.
