The Lowdown

G’day, Rusty here. Look, I’m gonna level with ya – the next week or so at Kamakura is pretty damn grim. You’re looking at a long stretch of tiny, weak surf with onshore winds messing it up, so don’t bother paddling out until we get deep into the back half of the outlook. The water’s sitting at 81°, which is about average for this time of year.

The first real chance of anything worth getting wet for shows up on Sunday the 23rd. Thursday the 22nd is still a write-off, with onshore southerly winds and swell struggling to hit 2 ft – it’s a no-go.

Now, onto the good stuff. Sunday the 23rd is where things get interesting. Morning sees a clean, cross-off breeze from the northeast with a 4 ft SSE groundswell, and the period is a proper 16 seconds. That’s a long-period swell, so it’ll have plenty of energy – you can feel the 668 in the combined energy. The afternoon pushes up to 4 ft from the SSE, still clean with that northeasterly cross-off. This is your first standout window, and it’s worth getting out for.

But the real gem, the absolute standout, is Monday the 24th. Monday morning is going to be magic. The wind drops to a glassy easterly breeze, absolutely zero chop, and the swell builds to 5 ft from the SSE with a 15-second period. The combined energy is a strong 1190, and the waves look excellent for experienced surfers. Kamakura is an exposed beach break, and with that long period, the sets will be clean, powerful, and lined up. It will be a bit big for beginners at 5 ft, but for anyone with a bit of experience, this is the session to aim for. Crowds are listed as “sometimes” here, but on a morning this good, expect company.

Tuesday the 25th morning keeps the run going with a glassy calm wind and a 7 ft SSE groundswell, also with a 15-second period – combined energy sitting at a very strong 1833. This is for experts only, as 7 ft on a long-period swell at an exposed beach can be a heavy paddle and big drops. The afternoon turns messy with a strong onshore southerly blowing 30 km/h (19 mph), so get your session in early. Wednesday the 26th fades fast, with onshore winds and tiny leftover swell.

So to wrap it up: the first 9 days are a write-off. Your best bets are Sunday the 23rd for a fun, clean day, and Monday the 24th morning for the absolute peak of the window. Tuesday the 25th morning is for the brave and the skilled. After that, it’s back to small, ordinary conditions. Keep your eyes on the horizon.

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.
