The Lowdown
Alright folks, Rusty here. Let’s be straight with you – it’s a rough patch ahead for Kimmeridge Bay. I’ve scanned the whole 16-day window, and honestly, there’s nothing I’d get out of bed for. The surf is either too small, too messy, or just plain blown out.
We kick off on Thursday the 3rd of September with a cloudy sky and a solid 15 to 22 mph cross-on wind. The swell is a weak 5 ft to 6 ft from the SW, but with a short period of only 6 seconds, the combined energy is a measly 151 to 176 (moderate). The water is a notable 68°, which is much warmer than normal for this time of year – over 5° above average, which is very unusual. But that doesn’t help the surf. It’s a choppy, lumpy mess, and the score is a zero.
Friday morning the 4th brings a bit of hope, with a 7 ft WSW swell and a NW cross-off wind making it clean. The combined energy jumps to 377 (moderate), and the period is still short at 7 seconds. But it’s only a marginal call, and the afternoon gets wrecked by a fresh cross-shore wind. Not worth it.
From Saturday the 5th, it’s a slow slide into nothing. The swell drops to 2 ft and below, with periods all over the place. The wind flips around, giving us some clean days but with zero wave height. The energy falls into the weak zone (29, 21, 82). There’s a 14-second period swell on Monday the 7th afternoon, but it’s only 1 ft, so that long period means nothing – just a long wait for a tiny, weak wave.
The whole second week is a struggle. From the 8th to the 18th of September, we’re looking at ankle-to-knee-high dribble. The biggest reading is 5 ft on the 10th, but it’s crossed-up and lumpy. The wind is either fresh or cross-on. The combined energy barely cracks 100 on a few days, mostly sitting in the weak zone. There’s a glassy morning on the 15th and 16th, but with 2 ft and 0.7 ft on offer, there’s nothing to ride.
This is a classic blank run for Kimmeridge Bay. It happens. The good news is the area is very consistent, so it won’t stay poor for long. Forecasts can change. But for now, leave the board at home.
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.
