The Lowdown
Alright folks, Rusty here. Let’s get into it. Honestly, for Kamakura, the next 16 days are looking pretty grim. Don’t get your hopes up. We’re basically staring at a long stretch of flat, weak, or messy conditions. The first real chance to even think about paddling out doesn’t show up until Monday, September 7th, and even then, it’s marginal.
The opening days, starting Friday, September 4th, are a write-off. Small, weak swell from the south around 2ft with a short period of 10 seconds, and cross-offshore winds are just not doing us any favors. The combined swell energy is a measly 83, so there’s just nothing to work with. Saturday and Sunday get even worse with more wind and rain, dropping to tiny 1ft and 0.7ft waves. By Sunday the 6th, the wind is offshore but it’s howling 25 mph, making it impossible to paddle into anything.
Things tease us a little on Monday, September 7th. A new S/SSE swell pushes in at 5ft to 6ft with a 10-11 second period, and the combined energy jumps to 923 – that’s a solid push of energy. But the wind is a light cross-onshore, creating wind ripples and making it a “marginal” call. It’s messy, but it might be the best we get for a while.
Tuesday, September 8th, is the one to circle. The morning looks promising with a 6ft south swell, 10-second period, and clean offshore winds from the NNE. The combined energy is a solid 730 and the forecast says “very good surf conditions.” This is your window. The afternoon gets blown out by a stronger cross-offshore, so hit it early. The water is a warm 80°, which is about normal for this time of year.
Wednesday the 9th still has some life with a dropping 4ft swell and light offshore winds in the morning, but it’s fading fast. After that, from Thursday the 10th onwards, we’re back to tiny, weak swell and messy wind. There’s a long gap of nothing worthwhile until the very end of the forecast window. On Friday, September 18th, the wind goes offshore again, but the swell is a pathetic 1ft to 3ft with a short period and low energy. It’s clean, but barely rideable.
So, for the standout: Tuesday morning, September 8th, at Kamakura is your best bet. Expect a solid 6ft south swell, clean offshore wind, and good energy. It’s not huge, but it’s the only real quality window in the entire outlook. The rest of the time, you’re better off finding something else to do.
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.
