The Lowdown
Alright, let’s talk about Kamakura. First off, it’s a beginner spot, but it doesn’t fire all the time, so you gotta be patient. The water here is sitting around 83°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus.
To be honest, the next two weeks are a real mixed bag, and for the most part, it’s looking pretty grim. We’ve got a long run of poor surf conditions stretching from late August all the way through the first few days of September. A lot of onshore wind, choppy water, and just not much to get excited about. The swell energy stays weak to moderate, with readings between 19 and 360 (combined energy). The waves are tiny, short-period, and messy.
Then we hit the 6th of September. That Sunday morning, a pulse of swell rolls in at 5ft from the south with a long period of 14 seconds. The energy jumps to 862 (combined energy) – that’s solid. This is a proper groundswell. But here’s the catch: the wind is cross-onshore from the SSW at 15 mph, making for a choppy surface. It’s not clean. Still, for an exposed break, there’ll be size. By the afternoon it’s 6ft and 13 seconds, but the onshore wind picks up to 25 mph. This is getting big for beginners, and with that wind it’s only really for the experienced crew. This pattern of solid but wind-affected swell continues through the 7th and 8th of September, with wave heights up to 6ft and energy readings over 1000 (combined energy). It’s strong, but messy.
The one true standout? Keep your eyes on the morning of the 11th of September. That Friday morning, things finally line up. The wind goes glassy – absolutely still from the ENE at just 3 mph. That is a major positive, telling you the surface will be pure silk. The swell is a clean 4ft from the south, with a 9-second period. The combined energy is 250 (moderate). For a beginner spot, this is the best on offer. It’s not huge, but with glassy conditions and that clean south swell, the waves will have shape and be totally user-friendly. The afternoon goes onshore again, so this is a short window.
The second week, around the 12th, is back to small and ordinary.
So, if you’re a beginner or just want clean, fun waves, the only date to circle is the morning of Friday, 11th September at Kamakura. It’s the one clear winner in a long stretch of poor conditions. The inconsistent nature of the break means you have to take those windows seriously.

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.
