The Lowdown
Alright, let’s get this straight. It’s a bit of a flat, grim picture out there for the next couple of weeks. I’ve been staring at the charts for Kimmeridge Bay, and honestly, it’s making me want to just wax up the log and go for a paddle, not a surf.
The water is sitting at a very unusual 67°, which is a good 5° warmer than normal for this time of year. That’s a seriously warm bath for September, and if we had any waves, you wouldn’t need a hood at all.
The problem is, from now until the 22nd, the surf is almost non-existent. We’re looking at a solid week and a half of tiny, weak, and messy conditions. The swell energy is in the double digits, and sometimes barely hitting 50, which is just sad. The wind is mostly cross-on or cross, and it’s choppy and lumpy. Not good.
We get a slight pulse on the 12th, with a 5ft WSW swell, but it’s a short-period 5-second windswell and the energy is only 109. That's just enough to close out and be frustrating. Saturday the 19th brings the biggest swell of the whole run, a 7ft SW with 414 energy, but it’s crossed by a brutal 25 mph wind. It’s going to be a messy, blown-out mess. If the wind was right it could be fun, but it will be a washing machine. Honestly, that setup looks more interesting for kite surfing than paddle surfing.
There is a brief moment on the 23rd, a Wednesday, that’s worth a mention. The wind goes light and cross-off, and it finally cleans up. The swell is only 4ft from the WSW with a 5-second period, and the energy is just 71. It’s surfable, but it’s very ordinary. The biggest issue is that it will be inconsistent. It’s the only day with a score of 1 out of 10 from the models, so this is our one and only real window.
After that, it’s back to tiny, blown-out slop for the rest of the period. There’s a long-period swell showing up on the 27th, with a 17-second period, but the height is only 1ft and the energy is 67. It’s clean, but there’s nothing to ride.
So, this is a classic case of a long flat spell. You’re better off waiting for that Wednesday the 23rd for a dawn session. The swell direction is WSW, which is right for the bay, but don't expect much. It’s the only standout, and even it is a struggle. The rest of the run, I’d be washing the car.
Keep the faith, it tends not to stay this poor for long.

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.
