The Lowdown
Hey folks, Rusty here. Let’s talk about Kimmeridge Bay.
Straight up, this 16-day outlook is a total dud. There’s nothing on offer for paddle surfing throughout the whole period. Every single session is marked as poor surf conditions, so don’t bother checking the cam. The gap in worthwhile surf runs from start to finish – 16 days of nothing.
The water at Kimmeridge is sitting at 69°F, which is about 7°F warmer than normal for this time of year – that’s really unusual, feels tropical, but that’s the only positive.
From Tuesday the 25th of August, it’s all downhill. Tiny swell, mostly around 3ft or less from the east and south-west, with periods between 4 and 8 seconds – that’s weak, short-period windswell. The combined swell energy is low, starting at 65, and never gets strong enough to push any decent waves through. The wind is almost always cross or cross-onshore, often fresh to strong, keeping the surface choppy and lumpy. There are a couple of moments with cleaner wind, like the morning of the 31st of August or the 6th of September, but by then the swell is a pathetic 0.7ft to 0.3ft. Not enough to ride.
On Saturday the 29th of August, the swell jumps to around 8ft from the south-west, but it’s hammered by a strong breeze onshore at 25 mph, making it a complete mess. The combined energy reads 754 – that’s a lot of power – but with that wind, it’s just a washing machine. That kind of setup on a reef spot like Kimmeridge is more for the kite surfers than anyone with a paddle.
A bit of longer-period groundswell shows up on the 4th and 5th of September – 12-second periods from the south-west – but it’s only 1ft. Way too small to matter, and the wind is still on it.
There are no standouts. Nothing to recommend. Zero scores across the entire forecast. For a spot that’s usually fairly consistent, this is a rare blank run. Could always change, but right now, it’s a hard pass.
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.
Kimmeridge Bay is 18 km (11 miles) from the city of Poole. If you plan a holiday in South Coast of England, look for hotels and other accommodation in Poole. Poole has rooms for a wide range of budgets as well as car hire and transport links.
