The Lowdown
Oi oi, Rusty here again, looking at the long-range picture for Kimmeridge Bay, and I’ve got to be straight with you – it’s mostly a bust. Over the next couple of weeks, we’ve got a whole lot of nothing and a few fleeting moments that almost get interesting.
Starting out on Tuesday, September 1st, it’s a rough scene. Tiny, weak swell from the WSW at about 2ft with a short period and very low wave energy (44). The wind is all over the place, making for bumpy, onshore slop. The afternoon gets even grimier with a strong cross-onshore blow. Wednesday and Thursday are more of the same – onshore winds, lumpy sea states, and waves barely worth a mention. The combined energy stays weak, mostly in the double digits, through the end of the first week. It's a complete washout.
Friday, September 4th afternoon goes clean when the wind shifts offshore, but the swell is down to a tiny 3ft with almost no energy (48). It's clean, but it's not surf. Saturday morning, September 5th, is flat calm with a glassy offshore wind, but the swell is a pathetic 1ft with virtually no energy (14). Not worth the rubber.
The second week doesn’t get much better. The only day that shows a spark is Friday, September 11th. The morning session has a 4ft SW groundswell, an 8-second period, and decent energy (192). The wind goes light offshore from the NNE, cleaning it up nicely. For a brief window, Kimmeridge Bay might offer a few rideable walls. It’s still just described as “surfable but ordinary,” so don't expect perfection. The afternoon goes glassy but weak again and scores a zero. This is the one and only day in the entire 16-day stretch that even gets a whisper of a positive score.
If you’re an intermediate who knows the Bay and you’re itching, that Friday morning the 11th is your only shot. After that, from the 12th of September through to the 16th, it’s back to tiny, poor-quality swell and messy, cross-shore winds. Nothing worth the drive.
It’s a bleak run for Kimmeridge Bay. A spot that needs the stars to align is just not getting them this time. Keep your eyes peeled for a change in the charts, but for now? The board stays in the van.
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.
