The Lowdown
Alright, grab a seat. Rusty here, lookin’ at what we’ve got cookin’ for Kamakura.
Honestly, for the next week and a half, we’re in a bit of a slump. Don’t get too excited, the surf is mostly flat or just plain tiny. The first real chance of anything decent won’t show up until Saturday the 21st, and even then, it’s only for the brave.
Let’s break it down. We’ve got a long stretch of nothing from now until Friday the 20th. Small, weak windswells in the 0.7ft to 4ft range, mostly from the SSE with periods under 10 seconds. That’s just not gonna cut it. The wind is often offshore or cross-off from the north, so the surface will be clean, but there’s simply no energy behind those waves. The combined swell energy barely hits 12, that’s real quiet.
The water’s a touch warmer than normal for this time of year, sitting at 81°, so you won’t need a thick suit.
Now, here’s the standout window. Saturday the 21st. The morning brings a solid 8ft SSE swell with a period of 13 seconds, and a combined energy reading of 2168 – that’s proper power. The wind is fresh and offshore from the NNE, so it’ll be clean, but with size like that, especially at a beach, it’s only for experts. This is big, powerful stuff. The afternoon on the 21st pushes even bigger, with 10ft SSE swell at 14 seconds, and the energy rockets up to 3826. That is a lot of water moving. The wind backs off to a moderate cross-off, which will help with shape, but at 10ft, this is serious. Kamakura is exposed to that SSE direction, so it’ll be lighting up, but the paddle out will be a mission and the takeoffs will be heavy. If you’re not on your game, stay on the sand.
After that, things drop off again. Monday the 22nd back down to 2ft. The tail end of the month shows a tiny blip of energy on the 29th and 30th of September, with chest-high 3ft to 3ft SSE swell and a period of 10-11 seconds. The combined energy climbs to around 243 with light winds on the 30th, so that could be a fun little clean-up session for a longboard or a fish. It’s not a standout, but it’s better than the flat spells.
Overall, keep an eye on that Saturday the 21st. That's the only day with serious size and power in the water. For everyone else, you’re waiting for the end of the month for a chance at some small, clean waves.

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.
