The Lowdown
Alright, let’s get straight into it. The next couple of weeks are pretty quiet for Kamakura, but there’s a real nice pulse building for the tail end of the window. We’re looking at a dry spell of small, weak surf for almost the first week, so don’t get your hopes up early.
First up, Kamakura (Kanagawa). We’ve got some tiny waves on Friday the 11th and Saturday the 12th, but nothing worth paddling out for. Waist-high at best, and the energy is pathetic (combined energy around 33). The wind is mostly cross-off or light offshore, which is clean, but the swell just isn’t there.
The real story starts shaping up toward the middle of the second week. From Friday the 18th, things start to build. The morning is still small with a moderate cross-off breeze, but by the afternoon, a longer-period swell begins to roll in. Swell height hits about 3ft from the SSE with a period of 16 seconds – that’s proper groundswell. The combined energy jumps to 486, which is moderate, and the waves are clean. It’s not a standout yet, but it’s the first sign of life.
Now, the main event: Sunday the 20th through Monday the 21st. This is where it gets interesting. The swell peaks on Sunday afternoon at 6.6ft from the south, with a 14-second period and combined energy roaring to 1909. Wind turns offshore from the NNE at 15 km/h, so you’re looking at gentle offshore and clean conditions. This is excellent for experienced surfers – but it’s too big for beginners.
Monday the 21st brings the biggest swell of the window. The morning is glassy, with the swell standing at 8.2ft from the south, period of 14 seconds, and combined energy hitting 2736. That’s strong energy. The wind is dead calm – glassy conditions. This is the highlight, but it’s strictly for experts. The afternoon turns onshore and messy, so get it early.
After that, the swell drops fast. Tuesday the 22nd is still decent at 5.2ft with offshore wind, but the period drops to 10 seconds. Wednesday and beyond return to small and ordinary.
So, bottom line: Kamakura is a no-go for the first week. The standout is Monday the 21st morning – 8.2ft south swell, glassy, powerful. That’s the one to circle on the calendar. Just remember, the water temperature is 82.2°F, which is a touch warmer than usual for this time of year.
Stay sharp and keep an eye on the sky.

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.
