The Lowdown
Alright folks, Rusty here. Let's have a look at what we've got coming down the line at Kimmeridge Bay. It's a pretty grim outlook, to be honest. We've got a solid 16-day window, but the surf is basically a no-show for the vast majority of it.
Looking at the whole picture, this place is getting hammered by wind from the wrong directions, mostly cross-onshore and straight onshore, which is just trashing any potential waves as soon as they show up. We're looking at a long stretch of messy, lumpy, and blown-out conditions with hardly a moment of clean lump to speak of. The water is a weird story too – the average temp for this time of year is shot, running much warmer than normal at 69°F.
Right, let's start from Thursday the 27th of August. It’s tiny with a weak 2ft swell from the SSW and a short, nasty 4-second period. The combined energy is basically nothing at all (10), and with a cross-onshore wind, it’s a big fat zero. That's the whole first week, really. We go right through Friday, the weekend, and into the next week with a frustrating mix of cross-onshore winds and blowing hard. By Saturday the 29th, the swell bumps up to 10ft but with a near gale cross-onshore, you'll be watching whitecaps, not riding waves.
The only flicker of life – and I mean the faintest flicker – comes around Saturday the 5th of September. The wind finally swings around to a light southerly, going offshore, and we see an 8ft swell from the SW with a period of 7 seconds. The energy is there (742). It's described as marginal, and the tide might be a factor, so it's definitely not a gimme. For a big wave, it's only going to be for experts anyway, being over 8ft.
And then it dies again. Sunday the 6th sees a proper 8ft swell from the WSW with a period of 8 seconds and massive energy (1066), but it's back to cross-onshore winds, turning it into a messy, choppy mess. That kind of setup at a beach-and-reef spot like this one? Looks a lot more interesting for kite surfing than paddle surfing.
Honestly, the rest of the run just fizzles out. Small, weak swells with the same cross-shore and cross-onshore slop. There's no standout session, no "go time" in this whole 16-day block. It’s a tough one.
Rusty, signing off.

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.
