The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s on the cards for Kimmeridge Bay.
Honestly, I’m looking at a pretty grim run for the next 16 days. The swell energy is all over the place, but the wind is just cruel. We’ve got a solid 31st of August with a 6ft swell from the WSW, but the WNW wind is howling at 19 mph, making it an ugly cross-off mess. The combined swell energy is moderate (535), but the conditions are just poor. The water is a balmy 69°, which is a whopping 7° above normal – seriously unusual for this time of year, so you might not even need a full wetsuit, but you'll still be battling the chop.
The whole first week is a write-off. From the 31st of August right through to the 7th of September, it’s just poor surf conditions, with the wind either cross-on or cross-off but never properly offshore. The swell is tiny, and when it does get a bit of size, like on the 3rd of September with 5ft, the wind is 22 mph cross-on (160 energy). It’s a lost cause.
We hit a dry spell from the 6th of September with nothing but tiny, blown-out dribble for several days. The real standout, and I mean the only faint glimmer of hope, is the morning of the 8th of September. The wind goes glassy – NNW at 3 mph – and we get a 1ft, 12-second swell from the SW. The combined energy is weak (67), but it’s glassy. The guidance says Kimmeridge Bay is a reef break that’s very consistent and works best on a SW swell, so this is actually the perfect direction. The catch is the swell is tiny, and it’s only graded as “surfable waves but very ordinary conditions.” It’s not going to be a classic, but it’s the only chance for a clean, even if small, wave.
After that, it’s back to poor conditions. The 15th of September brings a 6ft swell from the WSW, but with a 22 mph cross-on wind, it’s just a messy, lumpy powerhouse (249 energy). The next day, the 15th afternoon, it’s 7ft from the WSW with a 31 mph near gale cross-on – that’s blown out (401 energy). That’s way too big for beginners and only for the hardcore, but the wind will make it unrideable. It looks more like a kitesurfing setup than a paddle session.
The bottom line: there’s one glassy morning on the 8th of September for a tiny, clean reef wave. Mark it if you’re desperate, but otherwise, the whole 16-day window is a dud.
Rusty.

Information about the Kimmeridge Bay Surf forecast
The above surf forecast table for Kimmeridge Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kimmeridge Bay can be found by selecting the local surf guide option on the grey menu. Our Kimmeridge Bay 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 (Kimmeridge Bay) 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 Kimmeridge Bay 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.
