The Lowdown

Alright, Rusty here again, but this time in feet and miles per hour.

We’re looking at Kamakura and, honestly, it’s a bit of a rough stretch ahead. The next couple of weeks are looking pretty flat and messy, so you’ll need to be patient. There's a long gap of days with hardly anything worth paddling out for, so don't get your hopes up for a quick fix. The first real chance of anything decent doesn't come until Monday, the 7th of September, and even that is a bit of a long-range promise.

We kick things off on Monday morning, the 24th of August. There's a small, long-period groundswell from the SSE at about 2 feet, with a period of 18 seconds. That's a very long period, which usually means better shape, but with such a small size and the combined wave energy at 477 (moderate), it's just not enough to get excited about, especially with an onshore wind. That morning the wind is light, but it's onshore, and by the afternoon it picks up, ruining any chance. The water temp is about average for this time of year.

Tuesday the 25th is a write-off with stronger onshore winds and messy conditions. The swell bumps up a bit to around 5 feet from the south on Tuesday morning, but with 19 mph winds from the SSW, it’s just blown-out. Wednesday the 26th is not much better, with a cross-onshore wind and a marginal 4-foot swell.

Thursday the 27th offers a brief glimmer. In the morning we get a glassy, almost flat 1-foot swell from the SSW. The wind is virtually nothing and it’s glassy, so if you’ve got a log and you’re desperate, you might find a little something, but the energy is weak at 122. It’s surfable, but very ordinary.

Then we hit a dead zone. From Friday the 28th all the way through to Sunday the 6th of September, the surf is tiny and the conditions are poor. There's a long stretch of days with combined swell energy dropping below 100, sometimes as low as 16, which is basically flat. The wind is all over the place, mostly onshore or cross-onshore, and there's just no power. On Saturday the 29th and Sunday the 30th we get some clean, cross-offshore winds from the NE, but with waves only 1 to 2 feet, it's not worth the effort. There's a bit more energy on the 2nd and 3rd of September with some clean conditions from a NE wind, but the swell is still small and the wind is too strong at 16 to 22 mph. This is a long, quiet period.

Now, the one real standout in this whole outlook is Monday morning, the 7th of September. The forecast shows a clean 3-foot swell from the south, with a 12-second period. The combined energy is moderate at 319, but the real winner here is the wind: a light cross-offshore breeze from the NE at 6 mph, which will keep the faces clean. For Kamakura, this is the best on offer. It's not huge, but it will be surfable and clean, with that long-period groundswell giving the waves some push. Just keep in mind that this is a week and a half out, so it's promising but not locked in. That Monday morning session is the one to circle.

So, the bottom line: you're looking at a lot of flat, windy days, with one shot at some clean, fun-sized waves on the 7th of September. Keep your eyes on that one.

Rusty, signing off.

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.
