The Lowdown
Alright, folks, Rusty here. Let’s get into it for the Kamakura stretch. It’s a bit of a flat spell ahead, so don’t get too amped up for the next week or so. We’re looking at a long, slow grind, but there’s a flicker of life at the end of the horizon.
The next few days are going to be a real test of patience. We have a small pulse of south swell coming in this Friday morning with waves around 5ft. The energy is moderate, sitting at 962, but it’s onshore with a light breeze, and the conditions just look messy. Friday afternoon drops off in size to 5ft, but the wind clocks around, and the surf quality goes out the window.
Saturday is smaller again, down to 4ft, and while it’s clean early with a slight air, the period is a touch short at 11 seconds. It’s not doing much for us. The real killer is the onshore breeze picking up in the afternoon, spoiling what little there is.
By Sunday the swell is down to a dribble, with maybe 2ft, but that glassy morning wind is a saving grace. It’ll be tiny and weak, more of a longboard grovel than a proper surf. The energy has dropped right back to a weak 151. It’s the best of a bad bunch over the weekend, but that’s not saying much.
From Monday through to the middle of the following week, it’s essentially flat. We’ve got a multi-day gap with no real surf on offer. All the readings are under 2ft, with weak energy levels dropping to double digits. It's a barren stretch. The wind will be offshore at times, but with nothing to push around, it doesn’t mean a thing.
Now, if you’re willing to wait it out, there is a glimmer of hope. By the weekend of the 16th and 17th, we see the swell try to nudge back up, but it’s still pretty small, around 2ft. The more promising sign is a new south groundswell showing up for the 22nd of August. The swell is forecast to build to a modest 2ft, but the period is a proper 11 seconds, and the energy is pushing up into the moderate range at 153. The wind looks like it might be light offshore. It’s a long way out, so take it with a grain of salt, but it’s the only real standout in this entire window. For a break like Kamakura, which is inconsistent at the best of times, a south swell with a longer period is more on the money than the short-period junks we’ve been seeing. It’s not going to be huge, but it’s the one to keep an eye on.
As for the water, it’s sitting at a warm 80°, which is about average for this time of year, so no surprises there.
Honestly, this is a stretch to fix the fins, wax the board, and watch the cams. The good news is that a few breaks are fairly consistent, so it never tends to stay this poor for long. But for now, the board stays in the bag.
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.
