The Lowdown
Right, here’s the situation for Kamakura over the next 16 days. First off, I gotta be straight with ya – we’re looking at a pretty bleak run for a solid week. The first proper surf doesn’t really show up until Monday the 24th of August, and even then, it’s messy.
So, we’ve got a bit of a dry spell from now until Sunday the 23rd. The swell is tiny, the wind is mostly onshore, and the scores are flat. It’s a real bummer.
Then Monday the 24th of August morning brings a bit of life. The swell jumps to 4 ft from the SSE, with a super long period of 15 seconds. That’s proper groundswell energy – the combined energy is 1051 (moderate). But the wind is onshore from the S, and the report says it’s a marginal call. The afternoon gets bigger at 5 ft, but the wind picks up onshore and the score drops. It’s a tease.
Tuesday the 25th of August morning has a 6 ft swell from the S, period 14 seconds, combined energy up to 1404 (strong). Again, the wind is onshore, ruining it for us. The afternoon gets to 7 ft, but with a 22 mph onshore wind, it’s a total mess. This is not for the faint-hearted – anything over 8 ft is expert only, and the wind is going to make it horrible.
The rest of the week into early September is a write-off – small, onshore, poor conditions. There’s a glimmer on Sunday the 30th of August with a morning offshore breeze from the NNE, but the swell is only 3 ft from the SSE. The combined energy is 196 (weak). It’s surfable, but very ordinary.
Now, the real standout is way out there, on Thursday the 3rd of September. We’ve got a massive 8 ft swell from the SE with an 18-second period. The combined energy is a whopping 4624 (very strong). The wind is offshore from the NE at 19 mph, so it’ll be clean. But here’s the catch – that’s too big for beginners, and at 8 ft, it’s pushing into expert-only territory. The report warns the swell is predicted to be too big for this break. The afternoon gets even bigger, 12 ft from the SE with a 16-second period, combined energy 6411 (very strong). The wind stays offshore, but again, it’s predicted to be too big. For a beginner break like Kamakura, this is a spectacle, not a session.
The next day, Friday the 4th of September morning, is the real monster. An 18 ft swell from the SSE with an 11-second period, combined energy of 7470 (very strong). The wind is fresh offshore from the N. This is for experts only, and it’s a huge, powerful swell. The afternoon drops to 8 ft from the S, period 9 seconds, combined energy 1790 (strong), with offshore winds. Still big, but maybe a bit more manageable for the very experienced.
So, if you’re a beginner, this whole 16-day window is a no-go. For the experienced crew, the weekend of the 3rd and 4th of September is the only true standout, but it’s a long way off and the size is intimidating. The water temp is about 80°, which is pretty average for this time of year – nothing unusual there.
The break is inconsistent, so it’s not a surprise we’ve got a big blank run. Keep an eye on the forecasts, because things can change.

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.
