The Lowdown

G’day, Rusty here. Let’s cut to the chase on Kamakura for the next couple of weeks. The first week is a total dud, with barely a ripple. The first real chance doesn’t roll in until Friday, September 4th, but it’s a marginal call. There’s a long, flat gap before that.

The Overall Picture: The first six days, through to Wednesday, September 3rd, are a bust. Swell is tiny, mostly under 1.6ft, and the energy is weak (combined energy in the teens and twenties, barely hitting 33). The wind is often offshore or cross-off, so the surface is clean, but there’s nothing to push the board. The water is at 82.4°, a touch warmer than normal.

Friday, August 30th through Monday, September 1st: A few mornings with light offshore winds, but the swell is a pathetic 0.7ft to 1.0ft. The period is low (7-10 seconds), so it’s just wind chop. Not worth the paddle.

Tuesday, September 2nd: A glassy morning on Tuesday, September 1st, with the wind dropping to nothing, but the swell is still only 1.0ft. Pretty, but useless.

Wednesday, September 3rd: The swell nudges up to 2.0ft on Thursday morning, September 3rd, with a bit more energy (123), but the wind is cross-onshore, so it’s choppy and messy. Still no good.

Friday, September 4th – The First Real Hope: Finally, on Friday morning, September 4th, we see a jump. The swell hits 6.6ft from the south, with a clean cross-off wind from the northeast. The period is short (7 seconds), so it’s a bumpy, lumpy wave, but the energy is moderate (736). This is the first time the size is rideable, but the short period means it’ll be sectiony. The afternoon drops to 5.2ft, but the wind goes cross-on, spoiling it. The morning is your best bet, but it’s still only a “marginal” call.

Saturday, September 5th: Strong offshore wind (25 mph from the north) cleans it up, but the swell drops back to 2.0ft and the energy is low (92). That strong wind will make it impossible to paddle into those tiny waves.

Sunday, September 6th: A tiny, weak day with 1.3ft swell. Nothing.

Monday, September 7th – The One True Standout: This is your day. Monday morning, September 7th, is a beauty. The swell is 3.9ft from the south, with a long period of 12 seconds—proper groundswell. The wind is dead calm, glassy. The combined energy is moderate (525). This is the cleanest, most promising surf of the whole forecast. The long period means good shape, but at a beach break, the sets might run a bit straight. Still, with glassy conditions and that size, it’s a cracker. Crowds are “sometimes” a problem, so expect a few company.

Tuesday, September 8th: The swell gets too big for most. 11.5ft in the morning, 9.8ft in the afternoon, all from the south with a 12-second period. The wind is a strong cross-onshore, making it lumpy and dangerous. This is for experts only. The energy is massive (3250), but it’s a mess.

Wednesday, September 9th: A drop to 8.2ft from the south, still with a 12-second period. The wind is cross-off from the east-northeast at 12 mph, keeping it reasonably clean. This is a big, powerful groundswell. The energy is very high (1669 in the morning, 3342 in the afternoon). A good option for experienced surfers, but the long period at a beach break might make it fast and straight. The afternoon looks the best here.

The Final Week (September 10th – 13th): The swell slowly drops. Thursday, September 10th, is a step down to 3.9ft, and Friday, September 11th, is under 3.3ft. The wind is generally light and cross-off, so it’s clean but small. The real surprise is on Sunday, September 13th morning. A 7.9ft swell from the south-southeast with a very long period of 14 seconds. The energy is strong (2064). The wind is glassy. This is a serious, powerful groundswell with clean conditions. Again, the long period at a beach break might make it a bit closed-out, but for experienced surfers, this is a big, clean window. The afternoon turns onshore and messy.

The Bottom Line: The standout is Monday, September 7th morning. Glassy, 3.9ft, long-period south swell. It’s

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.
