The Lowdown
Alright folks, Rusty here. Let’s have a look at what Kamakura’s got cookin’ for the next couple weeks.
Honestly, the first week is a bit of a heartbreaker. There’s a solid run of poor surf from Wednesday the 19th right through to Monday the 24th. Tiny little slop, onshore winds, and just not enough energy to get excited about. You’d be better off stayin’ home and waxin’ your stick.
Tuesday the 25th morning sees a bit of a pulse, with a 5ft southerly swell rollin’ in. The combined energy is still weak (16), and the wind is on it, so it’s only a marginal call. The water temp is 81°, bang on average for this time of year, so no wetsuit drama.
Now, let’s talk about the standout. Saturday the 29th morning is your golden window. We’ve got a clean 5ft south swell with a decent 11-second period, light offshore NNE wind at 3 mph, and the combined energy is a solid 765. It’s not huge, but it’s well-shaped and glassy. Kamakura is an exposed break, and this one lines up perfectly with the optimum south swell direction. For a local spot, this is the pick of the bunch – clean lines, no chop, and that offshore breeze will hold it open.
Sunday the 30th morning is a close second: 4ft south swell, 10-second period, and a light cross-offshore breeze from the NE at 3 mph. Combined energy is 320, and it’s described as “good surf conditions.” Worth a paddle for sure, especially if you missed Saturday.
After that, things get messy again. Monday the 31st through to Thursday the 3rd of September is mostly onshore slop or just too windy. The 7ft to 10ft swells that pop up are all blown out by strong winds, so it’s a no-go for surfing – looks like a kiter’s playground more than anything.
Bottom line: mark your calendar for Saturday the 29th morning at Kamakura. That’s your best shot.

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.
