The Lowdown
Alright, this is Rusty. Let’s look at Kamakura for the next couple of weeks. Honest truth? It’s gonna be a long wait for anything worth paddling out for. The first week and a bit is pretty flat and uninspiring. We’re looking at a real drought of decent swell and clean conditions through most of the period.
For the first week or so, from Saturday the 15th right through to about Sunday the 23rd of August, it’s a real struggle. You’ve got tiny waves – mostly in the 0.7ft to 3ft range – and the wind is either onshore, cross-on, or just not playing ball. The combined swell energy is really weak, often below 100, which tells you there’s just no power in the water. The water temp is sitting at about 81°, which is pretty much spot on for this time of year, so no surprises there.
We do get a bit of a spike in combined swell energy on the 23rd afternoon, reading 246, and a long-period 17-second pulse from the SE, but it’s paired with onshore wind and rated as poor conditions. Not one to get excited about.
Now, the one thing that stands out in this whole 16-day run comes around Monday the 24th of August. The morning shows a bump in swell to 4ft from the SE, with a period of 16 seconds – that’s proper groundswell energy. The combined energy jumps to 736, which is moderate to strong. It’s a cross-on wind, but only a light breeze. That long period means the waves will have shape and push, but at a beach break like Kamakura, it might wall up and be a bit straight. Still, it’s the best on offer. The surf is marginal, but if you’re keen, this is your window. The afternoon holds similar size at 4ft but with the same caveats.
After that, it drops back off again into tiny, weak surf for the rest of the month. The 30th of August has a very long-period 21-second swell, but it’s tiny at 1ft and cross-on, so just a reminder of what could be.
Bottom line: if you absolutely need to get wet, aim for the morning of the 24th. Otherwise, it’s a lot of waiting for a few small, lumpy days. Don’t hold your breath.
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.
