The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Kamakura over the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week or so is a bit of a write-off. We’re looking at a long gap of flat, messy conditions. From Monday the 31st of August all the way through to Monday the 7th of September, the swell is tiny – mostly 0.7ft to 2ft – and the wind is all over the place, mostly cross-off or onshore. It’s a real bummer. The water temperature is sitting at 83°F, which is a touch warmer than normal for this time of year, so at least you won’t be cold while you’re waiting.
The first real sign of life shows up on Tuesday the 8th of September. The morning brings a 3ft SE groundswell with a period of 11 seconds, and a nice offshore wind from the NNE. The combined energy is moderate at 257. It’s an exposed spot, so it’ll pick up that energy, but Kamakura is a beginner’s break and it’s inconsistent. With a 3ft swell, it’s still manageable for the less experienced, but the offshore wind will make it clean. The crowds are a factor here, so be prepared for some company.
The real standout of the whole forecast, though, is Saturday the 12th of September. The afternoon session is looking prime. We’ve got a solid 6ft S swell with a 10-second period, but the combined energy is strong at 1133. The wind is light from the ENE, keeping it clean. This is the best on offer – a proper fun-sized swell with light winds. It’s pushing into the 5ft mark, so it might be a touch full for total beginners, but for anyone with a bit of experience, this is the one to circle on the calendar. The kicker is that the swell direction from the S is a good match for Kamakura’s exposed setup.
After that, things drop off again pretty quickly. The 13th and 14th see the swell back down to 2ft to 3ft, with onshore winds and rain, which is a proper letdown after that Saturday gem.
So, to wrap it up: the first week is a washout. The one and only true standout is the afternoon of Saturday the 12th of September. Get out there if you can.
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.
