The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for Kamakura.
To be straight with you, the outlook over the next couple of weeks is grim. There’s a huge gap right at the start with nothing worth paddling out for. The first real chance of a wave doesn’t come until Monday, 12 August, but even then, it’s only just surfable. Before that, we’ve got a solid week of small, weak, and messy conditions. From Monday 12th through to Sunday 25th August, it’s a real struggle to find a session that’s worth the wax. Let’s break it down.
The first sign of life is on Monday morning, 12 August. Kamakura sees a small 4ft swell from the SE with a short period of 6 seconds. The wind is light and cross-offshore from the ENE, so it will be clean. The combined energy is moderate (172). It’s still a beginner-friendly size, but don’t get your hopes up for any power. That afternoon, the swell drops back to 1ft, and the wind shifts offshore from the N, keeping it clean, but the size is tiny.
The rest of the week is a write-off. From Tuesday 13 August all the way through to Sunday 25th August, the swell is consistently tiny, mostly between 1ft and 2ft from the SSW or S. The wind is often offshore or cross-offshore, which would normally be a positive, but there’s simply no energy to work with. The combined energy readings are all in the low two-digit range, well under 100, indicating very weak wave energy. The water temperature is a warm 82°F, which is about 1°F above normal, so it’s pretty average for this time of year.
There’s a brief glimmer on Tuesday morning, 25 August. The swell picks up to 2ft from the SE with a period of 10 seconds, and the wind is light and cross-offshore from the NE. The combined energy is 64, still weak, but it’s the cleanest and most promising window in the entire forecast. The late-month period offers a slightly better chance, but this is still a far cry from good surf.
Look, the standout here is the Tuesday morning, 25 August session. It’s the only time the conditions line up for a clean, rideable wave. The rest of the fortnight is dominated by small, weak, onshore slop or tiny offshore waves that barely break. For a beginner, the size is safe, but for anyone else, it’s a frustrating wait. The truth is, if you’re looking to paddle, you’re better off waiting for a proper change in the forecast pattern. This stretch is a classic blank run for this area, and it’s not likely to produce anything memorable.

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.
