The Lowdown

Alright, grab your board shorts, let’s take a look at what the next couple of weeks are serving up for Kamakura.

To be honest, for the next few days, we’re looking at a pretty flat and messy picture. There’s not a lot of love out there right now. The waves are small, the winds are mostly onshore, and the water’s hanging right around 80°, which is pretty much normal for this time of year. It’s going to be a bit of a scratch-fest if you’re desperate for a paddle.

We’ve got a couple of days of tiny, weak ankle-biters to start, with the swell energy staying down in the low double digits (14, 37). Nothing to get excited about. Friday afternoon picks up a touch, but it’s still poor, and the onshore wind will have it all chopped up.

The weekend looks a little cleaner wind-wise, but the swell stays small and weak. Sunday morning looks glassy with a little cross-off breeze, but with only 1ft of swell on tap, it’s not really breaking with any power. You’re better off saving the energy.

Then things start to get interesting. The first standout of the window is Monday morning, the 24th of August. The wind is forecast to be glassy, the sky clear, and a proper south-southeast groundswell is pushing in. We’re looking at 4ft of swell with a 16-second period, and the energy reading jumps way up to 1389. This is the one to circle. It’s going to be a bit much for the beginners, but for anyone with a bit of experience, this is clean, powerful surf. The offshore wind is a huge bonus, making it worth getting up early for. It’s right up the alley for the exposed banks, and the long period will sort out the better sand bars.

The rest of that day and into Tuesday, the swell’s still there, but the wind swings onshore and brings a lot of chop with it, killing the quality. It’s still head-high to a bit over, but the forecast is calling it marginal at best. The energy is strong (2376, 2613), but it’s not going to be pretty. Wednesday morning looks like a washout with light rain and a cross-onshore wind, and by Thursday the 27th, we’ve got a serious storm system moving in. The swell jumps to 10ft, but it’s accompanied by 25 mph cross-onshore winds and the chance of thunderstorms. That's a full-blown paddle-out disaster, and the energy is massive (3537), but the surf will be a complete mess. That setup looks more interesting for the kite surfers than for us.

After that blow, things settle down and the swell starts to back off through the following week. We see a few days of cleaner, cross-off winds in the morning, but the size drops steadily. From the 29th to the 31st, there are some clean waist-high options on the cards with the swell around 3ft to 2ft, but don't expect any power. The period is all over the place, too.

We then have that long-range window at the start of September that just doesn’t come together. It's a stretch of small, weak surf with the energy levels dipping back down into the low hundreds, and some days into double digits. There’s nothing that will have you setting the alarm clock.

So, in a nutshell, the whole period is a mixed bag, but the clear winner is that Monday the 24th morning. Get out there for it before the wind chops it up. The following week is all about cleaning up, but the swell just isn't there to back it up.

This has been your look.

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.
