The Lowdown
Alright, Rusty here. Let’s talk about the surf outlook for Kimmeridge Bay.
To be straight with you, this is a tough stretch. The whole 16-day window looks pretty grim. There’s a lot of swell around, but it’s almost always paired with the wrong wind. The water temp is sitting around average for the time of year, nothing unusual there.
The first real week is a write-off. From Thursday the 27th all the way through until the end of the first week of September, the wind is just hammering the bay. It’s a constant cross-onshore drill, with wind speeds mostly between 9 mph and 34 mph. The swell is low and weak, often under 3 ft and with a short period, so the combined energy is tiny (39 to 6). It’s mostly small, choppy, and just not worth suiting up. Even when the swell bumps up a bit, like on Saturday the 29th when we see 8 ft to 10 ft from the SW, the wind is a strong onshore breeze with light rain. The energy climbs to 563 and 903 on those days, but it’s a messy, blown-out mess. That’s more of a kite-surfing setup than a paddle-surfing one.
We do get a little break heading into the second week. On Friday morning the 4th of September, things finally clean up. The wind turns light cross-off from the NW, only 3 mph, and the swell is 4 ft from the SW with a period of 7 seconds. The combined energy is 111, which is moderate. It’s surfable, but the conditions are only ordinary. The swell’s a bit short period, so don’t expect a lot of punch. Kimmeridge is a reef, so it handles the swell direction from the SW well, but with this short period, it might be a bit fat.
The next date that offers a sliver of hope is Monday the 7th of September in the afternoon. We get clean conditions again with a light cross-off breeze from the WNW at 6 mph. The swell is 4 ft from the WSW, but the period is short at 5 seconds, so the energy is only 87. Again, surfable but very ordinary.
Then, looking way out, on Friday the 11th of September, there’s a bit of a pulse. The morning brings a cleaner setup with a cross-off breeze from the NNE at 12 mph. The swell is 6 ft from the WSW with an 8-second period, and the combined energy is 447. That’s moderate energy. The guidance says this spot is a reef, best with SW swell, but this is a WSW swell, so it’s off-angle. The wind is clean, but the swell is a bit big for beginners and the period is still short. It’s a marginal call, but it’s the best looking option in the whole window. Don’t get your hopes up too much, though, as it’s a long way out.
The rest of the time is just small, weak, or blown out. Kimmeridge Bay is a consistent spot, but this is a blank run you can’t fight. Sometimes it’s like that.
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.
