The Lowdown
Alright, Rusty here. Gotta be honest with you, Kamakura is in a rough patch. We're looking at a long stretch of nothing, with no real surf for most of the next week and a half. The water's hanging around 82°F, which feels a touch warmer than normal for this time of year.
Right now, through the rest of this week and into the next, it's flat to tiny. The swell energy is pathetic, barely getting out of the single digits. You're looking at knee-high slop at best, with onshore winds making it a mess. Don't even bother.
We finally get a little something on Saturday, September 19th. The morning has an offshore wind from the North at 18 mph, with a southeast swell pushing 4ft and a period of 14 seconds. The wave energy climbs to a solid moderate 814, and with offshore winds, it'll be clean. But it's still marginal, just a 2 out of 10. It's rideable for the die-hards who just need to get wet, but nothing special.
Now, here's the only real standout, and it's a week out. Monday, September 21st is your day. A solid south swell rolls in at 7ft with a 13-second period, proper groundswell. The combined energy is pumping at 1563, that's strong. But the killer is the wind: light and variable, a gentle breeze from the NNE at just 6 mph, keeping things glassy. This will be excellent, but at that size, it's experts-only for Kamakura. The direction is nearly perfect from the south. Hit it in the morning before the wind swings onshore.
Honestly, if you miss that Monday, you might be in for a wait. The following Monday, September 28th, has another big one on the chart – a 8ft SSW swell with a very long 17-second period and massive energy of 3621. That's a ton of power. The wind looks offshore from the NNW at 9 mph that afternoon, which would be a dream. But that's way out there, so just keep it on your radar as a possibility.
For the rest of the days, it's back to small, messy, or blown out. A tough forecast, but that's the way it goes. Circle the 21st.
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.
