The Lowdown
Second Text (Imperial)
Alright, Rusty here. Let’s break down what’s in store for Kamakura. It’s a slow start, but there’s a couple of windows that could be worth the wait.
Right now, the water is about average for the season. The first few days are a total bust – tiny, weak swell and onshore chop. We’re talking knee-high slop, and the combined wave energy is barely hitting 46 (weak). It’s inconsistent, and even a beginner would be bored.
Thursday morning, a light offshore wind from the NNE cleans things up, but the swell is still a puny 2 feet at 10 seconds from the south. Energy is still weak at 92, and it’s raining heavy. Not a classic. Friday afternoon, the wind cranks up to a fresh offshore, and the wave energy finally hits 102 (moderate), but the swell is still only 2 feet. Clean, but tiny.
Then we hit Monday, the 7th of September. That’s the day. Monday afternoon, a solid 5-foot swell from the south rolls in with a 13-second period, and the energy jumps to 766 (strong). The wind is a light cross-offshore, so the waves will be clean and lined up. This is the standout: Kamakura, with a 5-foot south swell, clean, and that long period means real groundswell power. It’s not too big for the average surfer, but that 13-second period will give you some proper sets.
Tuesday, the 8th, gets bigger. Tuesday afternoon sees an 8-foot swell from the SSE with an 11-second period, and the energy is a massive 1616 (very strong). The wind is light offshore and clean. This is for experienced surfers only – over 8 feet, it’s a serious challenge, too big for beginners.
Wednesday the 9th, the swell peaks at 10 feet with an energy reading over 2000 (very strong). The wind is offshore, but the file says it’s too big for this break – a real big-wave day, only for the experts.
After that, it falls apart. Thursday the 10th is a total mess with a near-gale cross-onshore and blown-out 8-foot swell. That’s kite-surfing conditions, not paddling. The rest of the second week sees the swell fading and the wind turning onshore or messy. The 17th of September (Thursday) morning shows a small 4-foot south swell with a fresh offshore wind, but it’s marginal.
So, your best call is Monday the 7th afternoon. That’s the one. Tuesday the 8th afternoon for the experts. The rest is a long gap of flat or blown-out surf.
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.
