The Lowdown
Alright folks, Rusty here with the Kamakura report. It's a slow start, so let's walk through it.
The water temp is about 83°F, which is a touch warmer than average for this time of year. For the first week, through September 7th, it's mostly flat or tiny, with onshore wind or strong offshore gusts making it near impossible to ride anything. Swell energy barely registers, all under 110. Leave the board in the car.
Then, the morning of September 8th lights up. We've got a 6ft swell from the SSE at a 10-second period, with a light cross-offshore breeze. The energy jumps to a moderate 607, and the conditions are clean. That's your best window for a fun session on a 6ft swell – ideal for intermediate surfers.
Later on the 8th and into the 9th, the swell blows up to 10ft and 12ft, with extreme energy (3240 to 4888). That's experts only. The wind's okay, but the size is too big for the break to work well. That morning of the 8th is your standout for a good, manageable wave in clean conditions.
From the 10th through the 13th, it's blown out again with onshore gales and storms. The swell drops back to tiny, weak waves under 3ft. The 16th brings a long-period groundswell from the SW, but at under 3ft with strong onshore wind, it's not worth chasing. Circle the morning of the 8th.
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.
