The Lowdown

Alright folks, Rusty here. Let’s get into it. To be straight with you, the next week and a half is a real struggle. We’ve got a long, dry spell with hardly any surf worth paddling out for. After that, there’s a late window that looks promising, but it’s a long way off.

Right now, the only flicker of hope is a Tuesday morning session. Kamakura is showing a 4ft S swell, with a period of 9 seconds, and glassy conditions. The wave energy is moderate, sitting at 476. It’s an exposed spot, and with the wind flat and glassy, it’ll be clean. But it’s an inconsistent break, and the crowds can be around sometimes, so don’t expect an empty peak. The water temperature is about average for this time of year, so nothing wild there.

From Tuesday afternoon onwards, it’s a grim picture. The winds turn onshore or straight up howling, and the swell drops away. By Friday the 11th, we’re down to knee-high dribble with a weak 65 energy reading. Surfable, but ordinary. That trend continues right through to the 20th of September. There’s a solid stretch of nearly a week with nothing worth recommending; the swell just totally flatlines. The energy readings dip into the teens and twenties, which tells you the ocean is basically asleep. For a spot like Kamakura that’s inconsistent anyway, this kind of blank run isn’t a surprise.

Now, hold on to your boards, because around the 20th of September things start to shift. The 21st of September is the standout. We’ve got a SE groundswell arriving, 5ft, with a very long period of 15-16 seconds. The energy jumps to 832 on Monday morning and hits 1094 by the afternoon. Combine that with a moderate offshore wind from the N, and you’re looking at clean, powerful lines. This is a long-period swell, so it’ll be better shaped and have more energy, but it’s prone to breaking straight on a beach break. At Kamakura, a point or river setup would be ideal. Tuesday the 22nd keeps the swell pumping at 6ft and 7ft, with a 16-second period. The energy is huge, hitting 2058. The wind stays clean, but the swell is getting big—over 8ft by Wednesday morning, which is expert territory. This is a long-range call, so the forecasts might change, but as it stands, that’s the real deal.

Stay safe, check the tides, and if you’re a beginner, stay out of the water when it’s over 5ft. For the kite surfers, the whole first week of onshore slop might look more interesting than it is for us paddle surfers.

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.
