The Lowdown
Alright folks, Rusty here. Let’s have a proper look at the next couple of weeks for this little corner of the coast.
Honestly, it’s a grim stretch ahead for Kimmeridge Bay. We’re staring down the barrel of a long, flat spell with precious little to get excited about. The first week and a half is mostly a write-off, with hardly any wave energy to speak of. The water is sitting at 68°, which is much warmer than we'd expect for this time of year – a proper anomaly, that is.
The first real chance of getting wet doesn’t show up until Tuesday, August 11th. Even then, it’s a modest affair. We get some 4ft swell pushing in from the east, with a short, weak period of 5 seconds. The energy is feeble (80). It’s technically surfable, but the winds from the ENE are blowing cross-offshore, which should keep the surface clean. It’s not a standout by any stretch, just the least bad option in a dry spell.
After that, it fades back to nothing again. Wednesday the 12th still has a bit of 4ft east swell (96 energy), but the wind swings cross-shore from the east, messing up the face. Following that, the energy completely tanks for days. We’re talking swells under 2ft and barely a ripple on the surface.
Now, looking way out to the end of the run, the models are hinting at a pulse of energy arriving on Thursday, August 20th. We could see a 6ft swell from the southwest (255 energy) early in the morning, with light onshore winds. That’s the biggest swell in the entire window, and the energy is moderate. But it’s a two-week-away call, so take it with a pinch of salt. The period is a weak 6 seconds, so it'll be a messy, fat wave. By the afternoon, the wind cranks up from the southwest at 19 mph, turning it into a lumpy, choppy mess. That’s one for the experts only, as 6ft with a short period is a brute to paddle into.
All in all, the only window worth even looking at is the morning of Tuesday, August 11th, and maybe keep an eye on that Thursday, August 20th. For the rest, it's an exercise in patience. It won’t stay this poor forever, but for now, the board stays in the van.
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.
