The Lowdown
Alright, this is Rusty. Let’s be real about Kamakura over the next couple of weeks. The outlook is pretty flat and grim for a long stretch, so don't get your hopes up early.
Right now, we're sitting on almost nothing. A tiny 0.7ft to 1ft swell from the south and southeast with weak energy (around 10) and onshore breezes. The water temp is about average for this time of year. You’d be scratching for anything rideable. The first few days are a write-off – Sunday the 13th through to Friday the 18th of September, mostly poor surf with small, weak, messy waves and no real power. The wind might go offshore now and then, but there’s just no swell to work with. It’s a real dry spell.
There’s a long gap of quiet conditions until we see a genuine pulse around Saturday the 19th of September. That's when the energy finally kicks in – we’re looking at moderate to strong wave energy (1412) with a 6ft swell from the southeast. This swell has a very long period of 16 seconds, which means it's a proper groundswell. That long period will make it peel nicely at the better sandbanks, but it’s already getting up to a size that’s more for the experienced crew. The wind is fresh offshore from the north, so the surface should be clean. That Saturday afternoon bumps up to 6ft (energy 1533) and still offshore – that’s the standout of the whole forecast period.
Sunday the 20th holds similar size at 5ft with moderate offshore flow, but the period drops to 11 seconds – still decent but not as punchy. The real highlight, though, remains Saturday the 19th. By Monday the 21st, the swell is 6ft from the south-southwest, but the wind turns light cross-onshore, putting a bit of chop on the face. It might get fat and lumpy. Tuesday the 22nd morning is 8ft from the south, but with stronger cross-onshore wind, it’ll be choppy and hard to manage – that size is getting into expert-only territory anyway.
After that, the forecast falls apart again. Wednesday the 23rd looks blown out with a severe gale and tiny surf, and the rest of the month fades into tiny, weak, clean but unsurfable junk. The early part of the second week shows a bit of swell, but nothing that holds a candle to that Saturday blast.
So, the one true standout is Saturday, September 19th. Kamakura will have a solid 6ft to 6ft southeast swell with a very long 14-16 second period. The wind is fresh offshore from the north, so expect glassy, lined-up waves. This is for the experienced surfers – the size and power are no joke. It’s the only real day where everything clicks.

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.
