The Lowdown
Alright, it’s Rusty. Let me level with you – the surf for the next stretch is looking pretty grim around here. We’re looking at a long, dry patch where you’d be lucky to find a wave worth paddling for.
For the first week, from Saturday the 15th of August through the 23rd, it’s all small, weak junk. Swell is mostly under a foot and a half (0.4m to 0.6m), coming from the SSW or SSE, with periods all over the place from 6 to 11 seconds. The juice in the water is low, with combined energy readings barely breaking 100 most of the time, a brief bump to 128 or 135 on the 16th and 23rd (still just moderate). Winds are mostly messy, turning onshore by the afternoon. You might snag a clean little knee-high wave on Saturday the 15th morning, but it's nothing to write home about. The only glimmer in that first week is Saturday the 22nd morning: glassy conditions, 2-foot SSW swell at 10 seconds and the energy ticks up to 90. It’s surfable, but it's not great.
The real deal arrives on Monday the 24th of August. This is the standout. A proper groundswell hits: 5 to 6 feet of SSE swell with a long 17-second period. The energy reading blows up to 1746 and 1898 (very strong wave energy). The morning has a clean cross-off wind, but the afternoon goes totally glassy. This is for experienced surfers only – at 6 feet, it’s too big for beginners. That 17-second period means the waves will have serious power and shape, though it might tend to close out a bit on the beach breaks. Kamakura is the spot. If you score that glassy afternoon window, you’ll be in for clean, lined-up sets. Tuesday the 25th and Wednesday the 26th keep the swell going with 7 to 8 foot SSE swell at 15 seconds (very strong wave energy), staying clean in the mornings with cross-off breezes. By Wednesday afternoon, it’s forecast to hit 10 feet, pushing it too big for the break, so that day is strictly for the pros.
So here’s the plan: suffer through the flat spell, and pencil in the 24th through the 26th for Kamakura. The absolute best is the glassy afternoon of Monday the 24th. After that Wednesday, it all falls apart again with dropping swell and strong onshore winds from the SSW.
Hang tough. The ocean’s just catching her breath.

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.
