The Lowdown
Alright folks, Rusty here. Let’s have a look at what Kimmeridge Bay has cooking for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. The forecast is looking pretty grim for any proper surf. We’ve got a long, dry spell on our hands. From now through the end of August, and well into the first week of September, there’s just nothing worth paddling out for. We’re looking at a gap of nearly two weeks of poor conditions. It’s a real bummer, but for this area, a blank run like this isn't unheard of when the swell windows just don't line up.
Let’s break it down chronologically. Starting Friday the 21st, we’ve got a tiny 1ft swell from the SW with a short period of 6 seconds. The energy is weak (17). Sure, Friday morning has a light offshore breeze, but that swell is just too small and weak to do anything. It’s a non-starter. The whole weekend follows the same sad pattern with swells barely hitting 0.3ft.
Moving into the week, Monday the 24th sees a bit of a bump, with the swell trying to push up to 3ft from the ESE, but the period is a dismal 5 seconds and the wind is howling onshore at 18 mph. The energy picks up a little (62-180), but it’s just going to be a messy, blown-out wall of whitewater. Not surfable.
The situation doesn't really improve. We see some bigger numbers later in the week—like on Friday the 28th, where the swell hits 7ft from the SW in the afternoon. The energy is strong (398), and the wind swings offshore. But that’s misleading. That size, with that kind of period, on a reef setup like Kimmeridge Bay, is serious business. At over 8ft, it’s expert-only territory, and even then, the wind is so strong it’ll be a battle. The weekend of the 29th and 30th is just more of the same: big swell, strong cross-shore winds, and a lot of chop.
The first days of September are a washout again, with the swell dropping back to 1ft. Clean winds return on the 2nd, 3rd, and 4th, but with basically no swell to work with.
So, what’s the pick? Honestly, there isn’t a standout. There’s no “best on offer” here. If you were absolutely desperate, the cleanest conditions for a beginner-friendly wave might be on Thursday morning, September 3rd. We’ve got a light offshore wind from the N, and a clean 1ft SW swell. The energy is weak (13), but it’s the only time all period where a small, clean wave lines up. Don’t expect much, but you won’t get your head taken off.
Keep your eyes on the charts, lads. It can’t stay flat forever.
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.
