The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Kimmeridge Bay.
To be straight with you, the next couple of weeks are looking pretty grim for a proper surf. We’ve got a sixteen-day window, but honestly, the first real sniff of anything worth paddling out for doesn't show up until Saturday the 5th of September. Before that, we’re talking about a week of strong, messy winds and onshore slop that's just not going to deliver. The water temp is about average for this time of year, nothing special.
Right, so the only real glimmer of hope shows up on Saturday the 5th of September morning. The swell will be a touch under 5 ft from the WSW (6-second period), but the real story is the light WNW wind swinging cross-off, making it clean. The combined energy is moderate at 148, and it’s surfable. It’s not going to be epic, but it’s the cleanest we’ll see. If you're desperate for a paddle, this is your window.
Then the wind swings back onshore and chops it up again. Monday the 7th of September morning brings a light offshore N wind with a tiny 3 ft WSW swell, but the energy is weak at 75. Again, "ordinary" is the word the charts use. It’ll be clean, but small.
Looking further out, there's a morning on Sunday the 13th of September with a very long-period 17-second groundswell from the SW, but it's only 1 ft. That's a whisper, not a wave. It'll be clean with a NNW breeze, but there’s just no height. That’s really the only other spot of glass.
So, my pick for the whole period is Saturday morning the 5th of September at Kimmeridge Bay. It’s not a standout in the classic sense, but it’s the only time the conditions and a bit of size line up. The cross-off wind will keep the faces clean, and that 5 ft swell, though short-period, will give you something to push against. Given the crowds are "often" here, you won't be alone, but for this area in this window, it's as good as it gets.
Stay safe, and don't force it if it's ugly.

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.
