The Lowdown

Alright, let's talk waves. Rusty here. It's looking like a slow, frustrating week ahead for Kamakura, but don't lose hope just yet. We gotta sit through some real small stuff before the ocean wakes up.

Right now, the water is a touch warmer than normal, about 2° above average at 83°, but that's the only thing with any warmth. For the first few days, through the 1st and into the 2nd, we got barely a ripple. Swell energy is almost non-existent (24 to 33), and you'd be lucky to find a wave over an ankle.

We see a tiny bump on the 3rd, but with the wind going onshore, it'll be junk. The 4th and 5th are more of the same—weak and mushy. It's the kind of flat spell that tests your patience.

Now, things start to look a little more hopeful around the 6th and 7th. The energy picks up to 395, and we see some new SSE groundswell trying to fill in. It's still pretty small, under 3 feet, but the period is improving. It's clean but not powerful.

Okay, the first real, worthwhile surf shows up on Tuesday the 8th. We're looking at offshore winds and clean 4-to-4-foot waves. That afternoon is even better, going glassy with that same 4-foot SSE swell. It's not a slab, but it's clean, consistent, and fun. That Tuesday is definitely your pick for the week.

But here's the big one. On Wednesday the 9th, the ocean decides to show some real muscle. We're talking a massive jump to 8-foot, then 10-foot by the afternoon. The energy readings are off the charts (2215, then 3810). This is a proper, powerful groundswell. But, and this is a huge but, it's just way too big for Kamakura. It's gonna be a churning, dangerous mess. Unless you're a top-tier expert on a big-wave gun, stay off it. It's more of a spectator sport at that size.

The 10th is still huge but dropping, with strong 35 km/h offshore winds that will make it tough. The 11th is still interesting with a new SSW swell at 4-4 feet and a long period, but again, the wind is up.

After that, it fades fast. There's a glassy 3-foot morning on the 13th, but it's not much else. The run just peters out by the 14th.

So, the takeaway: For the average surfer looking for clean, fun waves, Tuesday the 8th is your day. Glassy and chest-high. For the experts only, the 9th is a huge and dangerous swell, remarkable but not for the faint of heart. Pick your days, and don't get caught out on the big one.

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.
