The Lowdown
Alright, Rusty here again, but this time in feet and knots for the imperial crowd.
So, Kamakura’s lookin’ pretty sleepy to start. There’s nothin’ worth paddlin’ out for for several days. Tiny, weak surf, hardly any energy. You’ll be waitin’ until at least the 19th of September to see a real bump.
That Saturday the 19th, we finally get some life. A clean 4ft swell from the SE with a 13-second period – that’s proper groundswell, with moderate energy (553). The wind is offshore and fresh, so it’s gonna be clean. For a beginner-friendly exposed beach break, that’s a nice little window. Water temp is about normal for this time of year.
Sunday the 20th keeps it going with 4ft to 5ft from the SSE, still offshore, and energy climbing (1030). A little big for total beginners, but still fun for the average surfer.
Now, Monday the 21st – that’s the one for the hardcore crew only. Swell jumps to 10ft in the morning, then a whopping 15ft by the afternoon, from the S and SSE, with a 14 to 15 second period. That’s very long-period groundswell, and the combined energy is huge – 3341 in the mornin’, 9066 in the arvo. That’s strong to very strong wave energy. Offshore wind in the morning, but that size at a beach break is expert territory only. Way too big for beginners.
After Monday, it’s a long, slow fade. Tuesday the 22nd goes small and onshore, and from Wednesday the 23rd right through the end of the month, it’s back to tiny, weak, and mostly unrideable. A couple of 3ft days around the 28th and 30th of September, but the wind is cross-onshore and messy.
Best bet? Saturday the 19th and Sunday the 20th for clean, fun, manageable waves. Monday the 21st if you’re a charger. After that, you’re lookin’ at a long flat spell. That’s the word from Kamakura.
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.
