The Lowdown
Alright, let’s get into it. To be honest, it’s a bit of a flat spell out there for Kamakura. We’ve got a long stretch of small, weak surf ahead, so you’ll want to keep your expectations in check. The first few days are looking pretty marginal, and there’s a real gap in quality before we might see anything worth getting excited about.
Sunday morning (the 9th) is about the best it gets to start. We’re looking at a small 2ft SSW swell with a 10-second period. The wind is glassy and light, which is a huge plus, making the water look clean even if the waves are small. It’s surfable, but very ordinary. The combined energy is a weak 151, so there’s just not much push behind it. The water temp is 81°, which is about average for this time of year, so no surprises there.
From Sunday afternoon, it drops off. The wind swings onshore and the swell fades. We’re looking at a few days of poor conditions and tiny waves. Monday (the 10th) has a bit of a cross-off breeze but the swell is down to 2ft to 2ft. Tuesday (the 11th) morning is glassy again, but the swell is a weak 2ft with not much behind it. The energy is down in the 70s, which is just weak. Tuesday afternoon brings a fresh onshore breeze, which is going to chop things up.
Wednesday (the 12th) through the weekend is a write-off. The swell is dropping to 1ft or less, and the winds are mostly cross or onshore. There’s a period of light rain and some fresh offshore breezes, but with wave heights that small, it’s not going to be worth the paddle. The energy is bottoming out, with values in the 40s and 50s. It’s a pretty bleak outlook.
The following week doesn’t offer much hope either. The swell stays small, mostly under 2ft, and the winds are all over the place. There’s a bit of a lift on the 22nd (Saturday) with a 2ft S swell and morning light cross-shore wind, but the energy is still only moderate (101). It’s still not enough to get excited about. The last day, the 24th (Monday), shows a 2ft SSW swell with glassy conditions, but again, it’s small and the energy is weak.
Honestly, there’s nothing here that’s a standout. The best you can hope for is a few clean but small waves on Sunday morning. For a beginner, these tiny waves are fine, but for anyone looking for a real surf, it’s a frustrating stretch. The swell is just too small and weak, and the wind is often not helping. If you’re desperate, you might get a few knee-high rollers, but it’s not going to be memorable. This is one of those times where you might be better off doing something else. The forecast can change, but right now, it’s looking flat.

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.
