The Lowdown
Alright folks, Rusty here. Let's not beat around the bush: the next couple of weeks are looking proper flat and messy. We've got a long stretch of small, weak surf ahead. The water's sitting at 80°, which is pretty average for this time of year, so at least it'll be a comfortable paddle.
The only real pulse of action kicks off this Friday morning, the 7th. There's a southwest swell pushing in at 5ft, with a solid 13-second period, and the combined energy reads 962. That's a moderate push, and it's the biggest we'll see for the whole run. But here’s the catch: it's coming from the south, which is a bit off for Kamakura. Still, Friday morning has light southerly winds and it's the best of a bad bunch. The swell is just over 5ft, so it might be a bit much for the beginners, but for the rest of us, it's worth a paddle out before the wind kicks up in the afternoon.
Saturday the 8th eases off to 4ft, and the energy backs way down to 324. It's surfable but nothing to write home about. Sunday the 9th is even smaller, down to 2ft, but we get a glassy morning with a slight offshore wind. It's clean, but tiny. You’d be on a log, and even then, you'd be hunting for a ripple.
From Monday the 10th through the end of the second week, it's a whole lot of nothing. We're looking at waves under 3ft, with energy readings dropping below 100, which is just weak. The wind is all over the place, mostly onshore or cross-off, and the swell period drops to that short-period range, which doesn't help. The 13th and 14th see some fresh offshore winds, but the swell is down to 1ft, so it's a waste of a good breeze. Honestly, from the 10th through the 22nd, there's not a single day I'd point you to. It's a dead stretch.
The only real standout in this entire run is that Friday morning session on the 7th. It's the biggest swell, the wind is workable, and the period is decent. It's not perfect, but it's the best we're going to get. Don't get your hopes up for anything else.
Alright, that's the story. It's a bleak one, but it is what it is. Keep the boards waxed and wait for the next pulse.
Rusty, out.

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.
