The Lowdown
Alright folks, Rusty here. Let's take a hard look at what’s coming up for Kamakura over the next couple of weeks. I won’t sugarcoat it—the start is grim. The spot is exposed to the south, but for days on end there’s just not enough push. Eventually, the second half of the period shows some serious potential, but don't get too excited too soon.
The first real glimmer of surfable energy doesn't arrive until Saturday the 19th, but it’s a marginal affair. A 5 ft south-southeast swell with a 14-second period rolls in, giving us a combined energy of 722 (moderate). The wind is a strong offshore from the north at 25 mph, which keeps it clean. But the strong offshore wind makes paddling into these waves a real chore, and the heavy rain Saturday afternoon doesn’t help the vibes. Honestly, this is more for the die-hards looking to stretch their legs.
The standout of the entire forecast lands on Sunday the 20th and continues into Monday the 21st. Kamakura goes off. Sunday morning sees a 6 ft south-southeast swell, period 13 seconds, with a combined energy of 1042 (strong). The wind is a moderate offshore from the north-northeast at 16 mph. That’s clean, lined-up surf made for experienced riders. If you’ve got the skills, this is your window.
Monday the 21st morning is even bigger—a 6 ft south swell, 14-second period, and a combined energy of 1425 (strong). The offshore wind holds. These are proper groundswell waves with a long period, so expect long sets and plenty of power. At Kamakura, that usually means better shape, but it can also tend to close out if you're at the wrong sandbank. Keep your eyes open.
Tuesday the 22nd gets wild, but it’s not for everyone. The morning shows a 8 ft south-southwest swell with a combined energy of 2144 (very strong), and the wind remains fresh offshore. The afternoon, though, spikes to a massive 18 ft south swell, 16-second period, with a combined energy of 13581 (very strong). That’s not paddle territory—that’s into the realm of experts only, and the file straight-up says it’s too big for this break. I’d steer clear unless you’re on a jet ski.
After Wednesday the 23rd, the energy fades fast. By Thursday the 24th and through the end of the month, we’re back to tiny, weak swells under 3 ft and combined energy below 138 (weak). The winds stay mostly clean from the north or east, but there simply isn’t enough wave to get excited about. The last week of September into early October is a dead zone for Kamakura.
In short, the only days worth circling are Sunday the 20th and Monday the 21st. That’s your best bet. Everything before is a bust, and everything after is a wash. Water temp sits right around 81°, which is a touch warmer than normal for this time of year. Not a wetsuit in sight.
Rusty, signing off.

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.
