The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way.

Well, the first few days are a write-off, to be honest. We’ve got a bit of a wait on our hands. Monday the 3rd and Tuesday the 4th are a total no-go with poor surf conditions and messy cross-off winds. The water’s sitting at 83°, which is a touch warmer than normal for this time of year, but that’s about the only good thing I can say for those days.

The first real glimmer of hope shows up on Wednesday morning, the 5th of August. Kamakura is looking at a solid 8ft swell from the SSE, with a 16-second period. That’s proper groundswell energy, and the combined energy is a meaty 3413 (moderate to strong). The wind is offshore and clean in the morning, so it’ll be well-shaped. But heads up—this is a big one. By Wednesday afternoon, the swell jumps to 10ft, and the report says it’s predicted to be too big for this break. That’s expert territory only. The stand-out session here is definitely Wednesday morning. It’s a consistent, exposed break, so it’ll be handling the energy, but it’s a beginner spot, so if you’re not up for an 8ft-plus wave, sit this one out.

Thursday the 6th still has size, 8ft to 8ft, but the wind swings cross-off and then cross-on, so it’s not as clean. Worth a look for the experienced crew, but not the best of the run.

Friday the 7th stays big, 8ft in the morning with cross-off breeze, but the afternoon gets choppy with cross-on wind. The real highlight after that initial pulse is Saturday morning, the 8th of August. Swell drops to a more manageable 6ft from the SSW, 14-second period, with a light cross-off breeze. The report says excellent conditions for experienced surfers, and the combined energy is still a strong 1792 (moderate to strong). The wind is light, so it’ll be glassy and clean. This is the pick of the week for decent, clean waves without the overwhelming size.

After Saturday, it quickly fades. Sunday the 9th drops to 4ft, and by Monday the 10th we’re down to tiny 1ft waves with a howling 25 mph offshore wind—strong offshore and clean, but you’ll be scratching to get into anything. The rest of the second week, from the 11th through to the 18th, is mostly small and weak. There’s a little bump on the 16th and 17th of August with 4ft to 5ft from the SE, 13-second period, and light winds, but the combined energy is weak (488 to 694), and the conditions are called marginal. It’s a pretty quiet end to the outlook, I’m afraid.

So, to sum it up: the standout is Wednesday morning, 5th of August, for the big, powerful groundswell, but only if you’re experienced. For a cleaner, more manageable session, aim for Saturday morning, 8th of August. The rest is a long stretch of small or messy 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.
