The Lowdown
Alright, Rusty here, let's talk Kamakura. It's a tough start. The first week is basically a write-off. From this Saturday, the 12th, right through to the end of Thursday, the 17th, it's tiny. We're talking shin-high slop at 0.7ft to 1.3ft. Even with a few glassy or offshore windows, the wave energy is weak—we're looking at values between 13 and 43, way too low to push anything worth paddling for. You'll be sitting out there waiting for a ripple. A lot of this period also brings onshore winds or rain, so not even pretty conditions.
Then, things finally get interesting. Friday the 18th morning, the swell starts to show. It jumps to 3ft from the SE with a 17-second period. That's a proper long-period groundswell, and the energy is solid at 484. Winds are fresh offshore from the N, and by the afternoon the swell hits 4ft with the energy climbing to 765. It's still in that "marginal" range for the break, but the building blocks are there. This kicks off a run.
Saturday the 19th is the first real standout. Swell is up to 6ft from the SSE in the morning, 14-second period. The combined energy is a strong 1265. Winds are strong offshore from the N at 30 km/h. That's clean, powerful surf, but at 6ft, it's pushing the limit for beginners and heading into intermediate-plus territory. By Sunday the 20th, it's still good: 4ft from the S with a 12-second period, moderate offshore winds, and energy around 597. The report says "expect very good surf conditions."
But the real story here, and the absolute standout of the whole 16-day window, is the swell that builds towards the end of next week. We're looking at Thursday the 24th through to Saturday the 27th. Thursday the 24th brings 5ft to 6ft, 16-second period, with clean cross-offshore winds from the NE. The combined energy is 1742, which is very strong.
Friday the 25th is the one to circle on the calendar. Afternoon session: 8ft of clean SSE groundswell, 16-second period, light offshore breeze from the ENE at just 10 km/h. The wave energy is massive at 3386. The report calls this "excellent surf conditions for experienced surfers." This is going to be a proper, powerful, clean swell at Kamakura. The direction (SSE) is good, and the offshore wind will groom it. That's your day if you've got the skills and a board for overhead waves. Saturday the 26th goes even bigger, 11.5ft. The report says that's too big for this break, so unless you're a charger on a gun, that's one to watch from the beach.
A bit of a shame the good stuff takes over a week to get here, but when it arrives, it delivers. Stay patient.

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.
