The Lowdown

G’day, it’s Rusty. Look, I’ll be straight with you – the next week or so around Kamakura is pretty flat. We’ve got hardly any size, and the wind’s been a mess. Nothing worth paddling out for until the morning of Saturday the 22nd, and even then it’s just a tiny 2ft glassy bump. That’s a real tease, because the energy’s only 60 – weak. It’s a long wait for something decent.

The real standout is shaping up for Tuesday the 25th of August. Kamakura is an exposed south-facing beach, and that morning we’ll see a clean 3ft SSE groundswell with a long period of 14 seconds. The energy jumps to 310 (moderate) and the wind is a light cross-offshore from the ENE. That’s clean, lined-up, and the water temp is about 81°, dead normal for this time of year. It’s not huge, but for a beginner-friendly spot that’s been dead, this is the best on offer. The long period means the waves will have shape, but at a beach break it might run a bit straight, so keep an eye on the sandbanks.

The window from Wednesday the 26th through Friday the 28th gets serious. On Wednesday morning, we’re looking at 5ft SSE groundswell, 14-second period, and a clean cross-offshore from the NE. Energy hits 827 (strong). That’s solid, but the swell is still a bit south, so it’s not perfect for Kamakura’s optimum south swell direction. By Thursday the 27th morning, the swell jumps to 5ft from the south, period 15 seconds, and pure offshore wind from the north at 19 mph. The energy is huge – 1161 (very strong). That’s a big, powerful, clean groundswell. But 5ft is getting too big for beginners, and the offshore is strong, making it a challenge. Friday the 28th morning sees 6ft south swell, 15-second period, and a strong north wind at 28 mph. Energy is 1432 (very strong). This is expert territory. The wind is so strong it’ll be hard to paddle into, and the waves will be heavy.

After that, the surf drops back down. Saturday the 29th morning still has 5ft, but the wind swings onshore from the SSW, ruining it. By Sunday the 30th, it’s back to 3ft and onshore. The last few days of the outlook into early September are a write-off – onshore wind, small swell, and poor conditions.

So, if you’re a beginner, that Tuesday the 25th morning is your window. For the experienced crew, the Thursday the 27th and Friday the 28th mornings are the real deal – big, clean, offshore, but you’ll need to earn it. The crowds at Kamakura can be a hassle sometimes, so get there early for the best of it.

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.
