The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Kimmeridge Bay over the next couple of weeks. If I'm being straight with you, it’s a pretty grim stretch for most of it. The wave energy is almost nonexistent for days on end, and when it does show a pulse, the wind is usually in the wrong place. We’re looking at a long, frustrating gap until the very end of the window where things finally start to look interesting.
Right now, through the rest of September and well into the last week, it’s mostly a write-off. We’ve got tiny, short-period slop from the WSW, barely cracking 0.7ft to 3ft, and the combined energy is pathetic, often sitting in the low double digits (like 18 to 55). The wind is a constant problem, mostly cross or cross-onshore, making things choppy and jumbled. There are a few clean periods on the 16th and 18th of September, with a light cross-off breeze, but the swell is just too small to bother with.
Then we get a bit of a pulse on the 27th of September. The swell pushes up to 6ft-6ft from the SW, with moderate wave energy (185-244), but it's coming with a strong cross-onshore wind from the SE, so it'll be lumpy and messy. Not the kind of session you want to write home about.
The real standout, and the only reason to keep an eye on this forecast, is the 28th of September – that’s a Monday. The combined energy jumps right up to 563 – that’s proper strong energy – with a 8ft SW swell. The wind looks like it’ll be light and offshore from the ENE first thing, keeping things clean. That’s the one. It’s a bit of a way off, so keep your fingers crossed, but if it comes together, Kimmeridge could have some proper waves with clean faces.
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.
