The Lowdown

Alright folks, Rusty here. Let's take a proper look at what’s on the table for Shichigahama. To be straight with you, it's a slow start and we’ve got a lot of flat days to get through before anything worthwhile shows up.

Right now and for the next several days, it’s pretty dismal. The swell is tiny, barely a ripple, with combined energy reading as low as 13 to 20. Winds are mostly onshore or light, and the water temp is sitting at a warm 81.1°, which is a touch warmer than normal for this time of year—so at least you’ll be warm while you’re staring at flat water.

We’ve got a real gap here. From Sunday the 13th all the way through to Thursday the 17th, there’s absolutely nothing worth paddling out for. The swell stays under 3.3 ft and the wind isn't doing us any favours.

Friday the 18th afternoon brings a bit of a tease. A long-period groundswell sneaks in from the SE with a 17-second period, pushing the combined energy up to 453. But the size is still just 2.6 ft and the wind is a strong 25 mph offshore. Clean, sure, but that wind strength is going to make paddling out a real mission. Hard to get too excited.

Now, Saturday the 19th is where things start looking a bit more interesting. Morning sees 5.2 ft of SE swell with a 14-second period and fresh offshore winds from the north. Combined energy jumps to 1109. It’s still described as marginal, but this is the first time we’ve got a proper wave size and decent conditions aligning. The afternoon holds similar at 4.9 ft. It’s not perfect, but it’s the best we’ve seen so far.

Sunday the 20th keeps the energy up with 5.6 ft on the afternoon and strong offshore wind. The combined energy hits 1361. Again, a bit marginal on the tide, but clean faces are on offer if you pick your moment.

Then we hit Monday the 21st and things go a bit wild. A big S swell comes in at 8.2 ft with a 14-second period, but the wind swings cross-shore and ramps up to gale force. The combined energy is massive at 2634, but the sea state is messy and dangerous—this is strictly for the experienced if anyone’s silly enough.

Tuesday the 22nd morning is genuinely too big for this break. We’re looking at 21.3 ft of S swell. That's huge. Combined energy is a staggering 14425. Only experts should even think about it, and honestly, it might be more of a kitesurfing day than a paddle day. The afternoon drops to 9.8 ft with offshore wind, but that’s still a heavy wave.

After that, it drops back down. Wednesday the 23rd through to the end of the period, we’re back to small, weak swell below 3.3 ft. The last few days offer glassy conditions but tiny waves, nothing to get excited about.

So the standout window? Honestly, Saturday the 19th and Sunday the 20th are your best bets. Consistent offshore wind, solid 4.9 ft to 5.6 ft SE swell, and long-period energy. It’s not firing, but it’s the most surfable run in this whole outlook. Don't sleep on the morning of the 19th.

Stay safe out there.

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.
