The Lowdown
Alright, pour a fresh one and let's talk about Kamakura. The forecast is a bummer for a while—flat spells and dirty conditions stretching out for days, so don't blow your wetsuit out trying to be a hero just yet.
The water here is sitting around 82°, just a bit warmer than usual for this time of year. Not much else going on.
The first real ray of light hits on the morning of Friday, September 11th. And I mean real light. We’ve got a clean morning with a 4ft swell rolling in from the SE, and a massive 18-second period. That’s a proper groundswell with a ton of push (energy reading of 1045). The wind is a light cross-offshore from the NE, so the faces should be smooth and lined up. This is the standout session in the whole 16-day window. That long period means the waves will have serious speed and length, but it might break too straight for some beaches—point and reef setups work best here. It's going to be too much for beginners, but for the experienced crew, it's a session not to miss.
Later on the 11th, swell rises to 6ft from the SE, but onshore wind from the SSW chops it all up.
By Saturday morning the 12th, we see a big 8ft from the SE with that same deep 18-second interval. The wave energy is huge (4348), but onshore winds ruin the package. Only experts should even think about it. Saturday afternoon the 12th kicks it up to a massive 10ft from the SE, period drops slightly to 16 seconds, and it’s blown out. That’s just too much swell for Kamakura—it’s going to be a churning, closed-out mess. The wave energy is over 4000—monstrous—but with the wind, it’s really a show for the kite guys, not a fun paddle.
So, here’s the word: you wait through a whole lot of flatness and wind. The best session, and honestly the only one that looks good, is that Friday morning, September 11th. If you can get in the water then, you’ll be smiling. Everything else is either flat, messy, or just too big.

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.
