The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this run for Kamakura is a bit of a mixed bag. We’ve got a decent pulse of long-period groundswell rolling through midweek, but it’s not the cleanest setup until the back half of the week. The water's sitting at 83°F, which is a touch warmer than normal for this time of year, so you can leave the wetsuit at home.
The standout window is Friday the 7th. Check it out: Kamakura sees a solid 7ft swell from the south, with a very long period of 15 seconds pushing a heap of energy (2032). That morning, we’ve got a light 6 mph offshore breeze from the northeast, keeping it glassy and clean. This is proper groundswell, so if you’re on a point or reef, it’ll be firing. The crowd factor is there – it’s “sometimes” busy – but for conditions this good, it’s worth the company. This is the pick of the whole forecast.
Leading up to that, Tuesday the 4th and Wednesday the 5th are building from 5ft to 8ft, with a mix of SE and SSE swell. The winds are cross-off, mostly from the NE, so it’s clean but not perfect. The energy is moderate to strong (1098 to 2414), but the commentary says “marginal,” so don’t expect top-tier waves. Thursday the 6th holds around 7ft, but the afternoon swings cross-on from the ESE, messing with the surface.
After Friday morning’s magic, the weekend drops off. Saturday the 8th is rainy and onshore, with 5ft but messy. Sunday the 9th has a light NE cross-off and 4–5ft, clean but small. By Monday the 10th, the swell fades to 3ft, and winds crank up to 22 mph offshore – hard to paddle into, and the energy drops to 534. From there, it’s a long, quiet stretch. Tuesday the 11th through Wednesday the 19th sees wave heights from 1ft to 3ft, with energy under 250. Winds are often strong offshore or cross-off, but with such small swell, it’s really just a flat spell. There’s a spark on Saturday the 15th morning with a 2ft swell and gentle offshore wind, but it’s tiny.
So, in short: Friday the 7th morning is your day. Get out there early. After that, it’s a waiting game.

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.
