The Lowdown
Alright, buddy, Rusty here. Let’s get you the lowdown for Kamakura in the numbers you know best.
First up, we’ve got a dry spell. From now until the morning of Friday, September 18th, it’s pretty much flat and miserable. Tiny, weak waves and mostly junk conditions. Nothing to get excited about.
Then things change. A proper groundswell shows up from the SSE on Friday the 18th with a very long period of 19 seconds. Swell height is 3ft, with combined energy sitting at 795 (moderate). A light cross-offshore breeze keeps it clean in the morning. By the afternoon it jumps to 5ft at 17 seconds and 1300 energy, but the wind turns onshore, so the early session is your go.
The real standout is Saturday the 19th of September, especially the morning. We’re talking 6ft of SSE swell at a 15-second period, combined energy of 1692 (strong), and glassy conditions. That’s clean, powerful surf, but it’s too big for beginners – this one’s for the experienced crew. With that long period on an exposed beach, the waves might run a bit straight, but when it’s that clean, you’ll find plenty of fun ones.
Sunday the 20th of September morning keeps the run going: 7ft from the S, 15-second period, over 2200 energy, and glassy with a light NNW wind. Big, clean, and punchy. All the same, it’s expert-only territory.
Monday the 21st of September is the peak. Morning shows 8ft of SSW groundswell at 16 seconds, with 3529 energy – that’s very strong. Calm and glassy. The afternoon holds steady at 8ft with a 15-second period, still glassy with a light NE breeze. This is the best window of the whole forecast: big, clean, and consistent. If you’ve got the skills, that’s your session.
Water temp is 82°F, which is a touch warmer than normal for this time of year – no wetsuit needed.
Crowds at Kamakura can be a thing, so expect some company on those good days.
Tuesday the 22nd of September sees a massive 13ft to 16ft swell from the S, but that’s just too big for this spot. Even for experts, it’s a washing machine. Not recommended.
From Wednesday the 23rd, the wind turns stormy and the swell drops fast, so that run is over.
Bottom line: Friday morning the 18th is a tester, but circle Saturday the 19th morning through to Monday the 21st. That’s your window: glassy conditions, solid groundswell, and strong energy. It’s as good as it gets around here.
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.
