The Lowdown
Alright, grab a brew and listen close. I’ve been staring at the charts for our patch and, to be honest, it’s a pretty grim outlook for the next 16 days. We’ve got a solid 9-day stretch of junk coming up before we even see a glimmer of hope.
The water is sitting at a very unusual 69° – that’s about 7° warmer than what we’d expect for this time of year. It feels like we’re in a different season.
Right now, there’s nothing on the table. The first week is a total write-off. We’ve got a day of light rain and strong winds on Saturday the 29th with a 10 ft SW swell, but it’s arriving with a near gale cross-onshore wind, so that’s a hard pass. That swell energy is pumping hard at 1105 (strong to very strong), but it’s completely blown out.
The only session that’s even worth a mention is the Saturday morning of the 5th of September. It’s far out, but it’s the only one that scores a 1 out of 10. We’ll have a 5 ft swell from the WSW with a period of 6 seconds, and the combined energy is a moderate 160. The key here is the wind. It’s going to be glassy, a slight air from the NNW. That means the surface will be clean. For this spot, Kimmeridge Bay, which is a reef break that’s fairly exposed to the SW, that’s about as good as it gets in this run. The swell direction (WSW) is close to the optimum (SW), so it should wrap in okay. Just don’t expect any power, that period is short.
After that, it drops right back off. The 6th of September has a cheeky 2 ft swell from the W with a 10-second period in the afternoon, but the cross-shore wind will chop it up.
So, to be blunt, there’s no standout here. The glassy morning on the 5th of September is the only real window for a paddle, and even then, it’s pretty ordinary. The rest of the 16-day window is a whole lot of wind and swell with no quality. Don’t hold your breath.

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.
