The Lowdown
Alright, Rusty here. Let's have a look at what Kimmeridge Bay has on offer. The outlook is pretty bleak for the first week and a half, with the early part of the period serving up very little in the way of rideable surf. There will be a stretch of days from Friday the 4th of September right through to the morning of Monday the 14th of September where the conditions are simply not worth paddling out for. After that long gap, we get a brief flicker of life.
For the first week, the story is all cross-shore and onshore winds, with small, weak swells struggling to get any rhythm. The combined wave energy is mostly weak, sitting in the two-digit figures, like 29 on Saturday the 5th morning or 42 on Friday the 11th morning. You'll see some moderate energy values like 362 on Friday the 4th morning, but with a short period of 7 seconds and onshore wind, it's all just messy, lumpy chop – not what you want on a reef. The wind states are a constant buzzkill, bouncing between "fresh cross-shore with lumpy cross-chop" and "strong cross-onshore and messy".
The one standout is the window on Monday the 14th of September. The morning shows some real promise. A solid 6ft groundswell out of the WSW, with a moderate energy of 178. The period is short at 6 seconds, so it won't have the long lines, but the real story here is the wind. It's clean with a slight air, meaning the surface should be glassy with a little cross-off puff. For Kimmeridge, that’s about as good as it gets this far out. It’s a reef break, so it holds that short-period swell better than a beach break would. This is the one to aim for if you’re an intermediate surfer. Later that afternoon, the swell pushes up to 8ft with energy spiking to 495, but the wind swings cross and the conditions will get lumpy again. That morning session is the pick of the bunch.
After that, the second week drops right back off again. The swell fades, and we're back to tiny, weak waves for the rest of the period.
So, to wrap it up: there’s a long, frustrating wait with no surf, but keep your eyes on the morning of Monday the 14th. That’s your best bet. It’s clean, there will be some size, and the reef should tidy up what the swell lacks in period.
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.
