The Lowdown
Alright, Rusty here, in feet and miles. Let's break it down.
We're looking at a real dry spell up front. For the first two weeks, you're better off checking the wind forecast for kites than paddling out. The wait is on until the 24th of August for anything worth a mention.
The first sign of life comes on Monday morning, the 24th of August. A SSE swell, 3.5 to 4 feet, with a 15-second period – that's a proper long-period groundswell. The energy is moderate (200), but it's blowing onshore, so it's a messy one. The spot is Kamakura, an inconsistent beginner break that's exposed to the south. The water temp is about what you'd expect for this time of year.
The real highlight, the one you want to plan for, is Tuesday morning, the 25th of August. The swell is around 4 feet from the SSE, still a long 12-second period, and the energy jumps to a solid 493. The wind is the game-changer here – glassy, with a light offshore breeze. That's clean, lined-up surf. For a spot that's been flat for so long, this is a gift. The crowd factor is "sometimes," so it might be a little busy, but for a 4-foot, glassy groundswell, it's worth the company. A bit much for a total beginner, but for everyone else, it's the best we've got.

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.
