The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Kamakura.
Alright, I gotta be honest with you. The next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long dry spell of weak, junk swell ahead. The waves are tiny, the energy is weak, and most of the time the wind is all wrong. You’ll be looking at the ocean and seeing a whole lot of nothing worth rushing for.
From Wednesday the 12th through to Saturday the 23rd of August, it’s a real struggle. The swell is consistently under 3 ft, mostly coming from the SSW or S, with periods that are all over the shop. The combined energy is way down in the basement, mostly double digits, like 105 (weak) on the 12th, and then dropping even lower. The water temp is sitting at 81.1°, which is about average for the time of year, so no surprises there.
You’ll get a few moments of glassy conditions and clean surfaces, but the swell is just too small and weak to bother with. Saturday afternoon the 15th and Saturday the 22nd might show a little pulse, but the forecast is calling it “surfable waves but very ordinary conditions” – and that’s about the best we get. The break is inconsistent at the best of times, and it’s certainly proving that now.
The only real standout, and I’m using that term loosely, comes at the very end of the outlook. On Thursday the 27th of August, the swell finally bumps up. The morning shows a 2.5 ft swell from the SSE with a 10-second period, and the combined energy climbs to 135 (moderate). By the afternoon, it’s pushing 3.5 ft from the SSE, also with a 10-second period, and the energy jumps to 257 (moderate). That’s the biggest, most energetic swell in the whole window. The problem? The wind is blowing onshore from the S at 22 mph in the afternoon. That’s going to chop it up. The morning is a bit lighter, so if you’re desperate, that might be your only chance. But for beginners, 3.5 ft is on the edge of too much, and with that onshore wind, it’ll be a messy, lumpy affair. This setup honestly looks more interesting for kite surfing than paddle surfing.
So, bottom line: this is a long, flat run for Kamakura. Don’t hold your breath.

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.
