The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Kamakura over the next couple of weeks.
Right off the bat, it’s a slow start. The first few days are a bit of a write-off – Saturday 1st August and Sunday 2nd August are looking tiny with weak, short-period swell. The water at Kamakura is sitting at 82°F, which is a touch warmer than normal for this time of year, so at least it’ll be nice to be in the water even if you’re just floating around.
The real action starts to build from Monday 3rd August. We get a decent groundswell from the SE pushing through, with periods hitting 16 to 17 seconds. The combined energy ramps up to moderate (303) by Monday morning, but the wind is a bit mushy and cross-off, so the quality isn’t there yet. Monday and Tuesday are still just building.
Now, Wednesday 5th August is where things get interesting. The morning has a solid 8ft SE swell with a 16-second period, and the combined energy is strong (3834). By the afternoon, it’s pumping at 10ft from the SSE. The wind is offshore and the conditions are clean, but here’s the catch – the wave comment says it’s predicted to be too big for this break. This is a serious groundswell, and at this size, it’s going to be a big, powerful, wonky mess at a beach break. This is strictly for the expert crew, and even then, you’ll want to be careful. The long period (16 seconds) will make for some heaving, straight lines, so it’s not your typical Kamakura session.
Thursday 6th August morning is your standout for the experienced surfer. The swell drops slightly to 8ft from the S, still a 16-second period, but the combined energy is still very strong (3588). The wind is light from the ENE, making for clean, glassy conditions. The wave comment is 'excellent surf conditions for experienced surfers'. This is the pick of the week. The water is still warm, and the offshore wind will keep it smooth. Just know that this size is only for those who know what they’re doing.
After that, the swell slowly fades through the weekend. Friday 7th August morning has a 6ft SSW swell with glassy conditions, but the wind turns onshore by the afternoon. Saturday 8th August is smaller and the wind is straight onshore, so it’s back to being ordinary.
The second week looks pretty flat and disappointing. From Sunday 9th August right through to Sunday 16th August, the swell is small, mostly under 3ft, and the wind is often strong or onshore. There’s a brief flicker on Sunday 16th August morning with a 6ft SE swell from a long period (14 seconds), but the combined energy (1208) is moderate and the wind is cross-off. It’s a marginal call, nothing to write home about.
So, the best bet by far is Thursday 6th August morning. If you’re an experienced surfer and can handle a solid 8ft S groundswell with clean, light wind, that’s your window. For everyone else, it’s a waiting game for a better window later in the month.
Rusty.

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.
