The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Kamakura over the next couple of weeks.
To be straight with you, it’s a lean run. The first few days are just not worth paddling out for. We’ve got a real stretch of small, weak surf and mostly dodgy wind. The first recommendation doesn’t come until Thursday morning the 13th of August, and even then it’s really just a knee-high bump at 0.5m (about 2ft) from the S with a moderate offshore breeze. It’s clean, sure, but the combined swell energy is a very weak 60 – just a dribbler. You’ll be scratching for anything.
The pick of a pretty average bunch looks like Thursday morning the 20th of August. We’ve got a little 0.7m (about 2ft) swell from the S, but the magic is in the wind – it’s totally glassy, dead calm. The water temp is about average for the time of year. The combined energy ticks up just into the moderate range at 101, so there’s a tiny bit more push. Kamakura is an exposed beach, and with that S swell you’ll find a few clean little runners. Don’t expect any power, but if you need a fix, it’ll be the most pleasant session of the lot.
Later on, we have a promising but less certain call for Wednesday morning the 26th of August. The swell jumps to 1.1m (about 4ft) from the SE (11-second period) with glassy conditions again. The combined energy hits a solid 286 – moderate, but much better. That long period (over 11 seconds) means more shape, but at a beach break it can get a bit straight. Still, with absolute zero wind, it could be the best one on the forecast, if it holds. The afternoon of the 25th of August shows some serious size (2.0m, about 7ft) but with a strong onshore wind and crazy energy of 1429 – that’s ugly, choppy, and only for the brave. Stick to the glassy morning the day after.
Overall, it’s pretty quiet. Most days you’re battling poor surf and iffy wind. The glassy windows on the 20th and the 26th are your best bets. Don’t hold your breath.

Information about the Kamakura Surf forecast
The above surf forecast table for Kamakura provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kamakura can be found by selecting the local surf guide option on the grey menu. Our Kamakura 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 (Kamakura) 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 Kamakura 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.
Kamakura is 2 km (1 miles) from the city of Kamakura. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Kamakura. Kamakura has rooms for a wide range of budgets as well as car hire and transport links.
