The Lowdown
G'day, Rusty here. Look, I've got to be straight with you – the next couple of weeks at Kimmeridge Bay are looking pretty grim. We've got a long stretch of poor surf conditions ahead, so don't get your hopes up for any decent waves. The water’s sitting at 69°F, which is a whopping 7°F warmer than usual for this time of year – that's a very unusual anomaly, making it feel more like a bathtub than the English Channel.
The first real blip of anything surfable doesn't show up until Tuesday, September 1st. That morning, we'll see a small 4ft swell from the southwest, with a light offshore breeze from the north-northwest, making the conditions clean. The swell energy is weak though, at just 80. It's labeled as "surfable waves but very ordinary conditions," so don't expect much. That's your only real standout in the whole 16-day window, and even that's a pretty average offering.
Before that, from Wednesday, August 19th, through to Monday, August 31st, it's a complete write-off. Cross-onshore winds, choppy and lumpy conditions, and tiny, weak swells dominate. Even when the swell bumps up a bit, like on Thursday afternoon, August 20th, with a 5ft swell from the west-southwest (moderate energy at 166), the cross-shore wind makes it a mess. There's a brief moment of clean conditions on Saturday, August 22nd, and Sunday, August 23rd, but the swell is a pathetic 0.3ft to 0.7ft – not even worth paddling out for.
From the 28th onward, we get some clean conditions with cross-offshore winds, but the swell is tiny, and the wave energy is weak. The window on Tuesday, September 1st, is really the only thing to consider. After that, it's back to poor conditions with onshore winds and choppy seas.
So, the bottom line: Kimmeridge Bay is pretty much a no-go for the next two weeks. The one morning on Tuesday, September 1st, might offer a small, clean window, but it's nothing to write home about. Keep an eye on the forecasts, but for now, I'd be looking for another hobby.
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.
