The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window for Kamakura, and honestly, for the first week or so, it’s a bit of a flat spell. From Sunday the 16th through to the 23rd of August, the swell is tiny and the wind is mostly onshore or cross-shore, so there’s really nothing worth paddling out for. You’re looking at a solid week of waiting.
The first real glimmer of hope shows up on Monday the 24th of August. The morning session is the standout. We’ve got a clean 4ft swell rolling in from the SE with a super long 16-second period – that’s proper groundswell energy. The wind is a light cross-off from the NE, so the faces will be smooth. The combined energy is moderate (750), but it feels bigger because of that long period. This is a point-break or reef-friendly wave; it’s going to peel nicely. The water temp is about 81°F, which is around normal for this time of year.
Into the week of the 25th, the swell picks up properly. Tuesday morning the 25th sees 6ft from the SSE with a 15-second period, but the wind is straight onshore from the S, which will chop it up. The combined energy is strong (1162), but the conditions are marginal. Not the cleanest.
The real standout, the one you’ve been waiting for, is on Monday the 31st of August. The morning session is a beast. We’re looking at a solid 8ft swell from the SSE with a 14-second period. The combined energy is very strong (2816). The wind is light and offshore from the NE, so the lines will be perfectly clean. This is excellent surf, but at 8ft, it’s one for the experienced crew only. Beginners should sit this one out. The water is still warm, around 81°F, which is about average for the season.
So, the two true standouts are the clean, long-period groundswell on Monday morning the 24th, and the bigger, more powerful, clean swell on Monday morning the 31st. The 31st is the better of the two for those who can handle it.
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.
