The Lowdown
Right then, let’s have a look at what’s on offer for our bit of coast. The main spot we’re talking about is Kimmeridge Bay, a reef setup that’s fairly exposed to a south-west swell.
The honest truth is, the next week and a half looks pretty grim for a proper paddle. There's a real gap here with no good surf to speak of. From Sunday the 30th of August all the way through to Friday the 11th of September, the conditions are just poor. The wind is either too strong, too cross-onshore, or the swell is tiny and messy. You’ll see a bit of size on the 3rd of September with a 7ft WSW swell, but it’s accompanied by a fresh cross-onshore wind that’s just going to chop it up into a lumpy mess. The combined energy might be moderate (424) but the quality is just not there for a surfer. It’s the kind of setup that looks more interesting for kite surfing than paddle surfing. The water temperature is about average for the time of year.
Then, finally, we get a glimmer. On Saturday the 12th of September, the morning shows a little promise. It’s not a standout by any means, but it’s the best we’ve got. We’re looking at a 4ft swell from the WSW, with a clean, cross-offshore wind from the ENE at just 6 mph. That’s a light breeze, and it’ll keep the surface clean. The combined wave energy is moderate (114). The waves are surfable, but the description says “very ordinary conditions,” so keep your expectations in check. It’s a small window after a long dry spell.
After that, the wind swings back onshore and the swell gets messy again, so that Saturday morning window is the one to keep an eye on. It’s not a classic, but it’s something.

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.
