The Lowdown

Alright, I’m looking at the charts here, and honestly, it’s a pretty grim run for us. We’re in for a proper drought. Most of this 16-day window is flat or blown out, so don’t be in a rush to load the boards.

We start right now, and there’s nothing worth paddling out for. Tuesday the 25th of August through to the morning of Saturday the 6th of September is a dead zone. Over a week and a half of junk. Swells are tiny, wind is messy onshore, and the few moments of glass or offshore wind only hit when the waves have already given up. It’s that kind of pattern.

Then, finally, we get a flicker of life. On the morning of Sunday the 6th of September, Kamakura starts to wake up. We’ve got a 3ft SSE groundswell with a 12-second period and a moderate offshore wind from the north at 12 mph. The combined energy is moderate (277). That offshore wind will keep the surface clean, which is a huge plus after so much rubbish. The swell direction is coming from the SSE, but the spot really wants a southerly direction to work best, so it’s not a perfect match, but after two weeks of nothing, we’ll take whatever we can get. It’s a beginner-friendly break, but with the swell being under 5ft, it’s still very doable for most. The water temp is sitting at 82°, which is about average for this time of year, so no shock to the system.

Sunday afternoon holds a slightly bigger 4ft SSE swell (11 seconds), but the wind swings cross-offshore and the combined energy ramps up to 738 (moderate). It’s hard to call that a standout, because it's clean, but the guidance says it's more marginal.

The actual standout is the morning of Tuesday the 8th of September. The swell drops back a little to 4ft from the SSE, but the wind is a clean cross-offshore breeze from the NNE at 9 mph. The combined energy is 208 (moderate). The period is only 8 seconds though, so it’s a shorter-period wind swell, not that long groundswell feel. It’s clean and surfable, and after the long wait, it’s the best we’re going to get. Crowds at Kamakura can be a hassle, especially after such a long flat spell – everyone will be frothing to get wet, so expect the peak to be busy.

Keep in mind, that Tuesday 8th September call is a week and a half away, so it’s promising but not locked in. The rest of the forecast falls away again into tiny, weak waves and onshore wind, so if you see a window on that Sunday or Tuesday, jump on it.

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.
