The Lowdown
Alright, this is Rusty. Let’s get straight into it.
Right now, it’s a tough start for Kamakura. The first week is basically a write-off. We’ve got heaps of rain, wind from all the wrong angles, and swell that barely reaches your knees – nothing over 2 ft for days. It’s frustrating, but that’s how it goes sometimes. The water temp is sitting at 82°, a touch warmer than normal for this time of year, so at least it’s nice if you’re just floating.
Things start to flicker around Friday the 18th. That morning we see a sudden jump in energy – combined energy of all swells directed here is 645 (moderate) – as a new SSE groundswell pushes in at 4 ft with a very long period of 16 seconds. The wind is a solid offshore from the N at 18 mph, so it’ll be clean. But at that size and with that period, a beach break like Kamakura might throw up straight walls. You’ll want to be sharp. By the afternoon, it’s up to 6 ft with even more energy (1542), still offshore, but now it’s getting into expert-only territory for the paddling.
Saturday the 19th is the standout. Morning brings 7 ft of SSE groundswell, period still a meaty 14 seconds, combined energy at 1469 (strong), and offshore NNE breeze at 15 mph. Those are prime conditions for experienced surfers – steep, fast walls. Afternoon drops to a cross-off but the swell hangs at 7 ft. This is the one to circle on the calendar.
Sunday the 20th and Monday the 21st keep the fun alive but dial it back a notch. Both mornings give us about 5 ft of S to SSW groundswell with gentle offshore winds, energy in the 700–800 range (moderate), and clean faces. Still plenty of push, but friendlier for those who aren’t charging.
After Monday afternoon, the wind gets messy and the swell drops significantly, so the second half of the window is nothing to write home about. A couple of blown-out days and a big storm risk later on. No real standouts past the 21st.
So, the clear winner is Saturday the 19th morning at Kamakura. That’s where you want to be. 7 ft, SSE, long-period groundswell, 15 mph offshore wind – that’s the kind of combo that gets the heart pumping. Just know it’s for the experienced crew; beginners, give this one a miss.
Stay frothy,
Rusty

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.
