The Lowdown
Alright, let me give it to you straight for Kimmeridge Bay. The water is a very unusual 69° – that's nearly 4° warmer than average for this time of year, which is wild. But the surf outlook is a tough one. There are no good options in this 16-day window, not a single standout. It's a long blank run of poor surf conditions, which is more normal for this spot when the swell and wind don't play ball.
We kick off on Friday, August 21st with a tiny 1ft SW swell at 6 seconds. The morning has a clean offshore breeze from the NNE at 9 mph, so at least it's glassy, but the waves are too small to do anything with. The afternoon turns cross-shore and even weaker. Saturday the 22nd is almost flat: 0.3ft of S swell with a very long 15-second period, but that doesn't matter when there's nothing to ride. Wind is cross-off then onshore. Sunday and Monday stay small and choppy with onshore or cross-onshore wind.
Then Monday the 24th brings a spike: 6ft of E swell at 6 seconds, with combined energy at 242 – that's moderate energy. But the wind is screaming from the east at 25 mph, cross-shore and messy. This is kite surfing territory, not paddle surfing. Tuesday the 25th morning cleans up with 4ft E swell and cross-off wind, but it's still rated poor.
The pattern keeps going: moderate swells pop up but always with cross-onshore wind. On Friday the 28th afternoon, we get 8ft from the SSW at 7 seconds, and the energy jumps to 529 – that's strong wave energy. But with a 28 mph cross-onshore, it's messy and only for experts, and it's still described as "surfable waves but very ordinary conditions." Saturday the 29th has some SW swell but fresh cross-shore wind.
The only glimmer is Thursday morning, September 3rd: 6ft SW swell, 6-second period, combined energy of 261, and glassy conditions with just 3 mph wind from the WSW. That's the closest we get to something surfable, but even then it's "surfable waves but very ordinary conditions" and scores only a 1 out of 10. The afternoon goes cross-onshore again.
So that's the picture. No proper standouts, no clean swell windows. The region is just not giving us anything this time. Forecasts can change, but for now, it's a waiting game.

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.
