The Lowdown
Alright, Rusty here, checking in with a look at the surf ahead. The window opens up around Monday morning the 25th of August, with the first bit of potential swell starting to show. Before that, the weekend is flat as a tack – nothing doing on Sunday the 23rd or Monday the 24th. Just a heads-up, the water temp is sitting at 27°, which is about normal for this time of year, but it's feeling like bathwater.
So, for Kamakura itself, things start to creep in on the 25th. Early Tuesday morning the 25th has a 5ft swell rolling in from the SSE with a period of 13 seconds. Winds are onshore from the SSW though, which kills the quality. There's moderate wave energy kicking around (952). It's not good. That onshore wind and a bit of a lumpy look to it means it's a pass. Wednesday the 26th is more of the same – bigger swells, but blown out by a strong SSW wind. The setup looks more interesting for the kite crew than for a paddle surfer.
The real bright spot? It's a long way off, so keep your expectations in check, but look at the window around Wednesday morning the 2nd of September. That's the standout. Kamakura gets a clean 4ft SSW swell with a long 14-second period. More importantly, we get a solid 16 mph offshore wind from the NNE. That's the good stuff. The combined energy is moderate (597), but that offshore wind will groom it into clean lines. It's not a monster, but for Kamakura, that's as good as it gets in this forecast. The following afternoon and Thursday the 3rd still look promising, with a 4ft SSW swell and a cross-offshore wind, keeping things clean. The energy builds a touch on Thursday afternoon (814).
After that, it gets messy again. Friday the 4th has some size with the SSW swell around 4ft, but it's getting chopped up by strong cross-offshore winds. Then the weekend of the 5th and 6th is a write-off. We’re looking at a 7ft SSW swell on the 5th, but with a howling 28 mph cross-shore wind and a combined energy of 2792. That’s just blown-out, dangerous conditions best left to the experts, if anyone. By Monday the 7th it drops right back, with glassy conditions in the afternoon but only a tiny 2ft swell – surfable but very ordinary.
So, bottom line: sit through the next couple of days, and the first week of September has a couple of early mornings that are worth the alarm clock. That Wednesday the 2nd is your best bet.
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.
