The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Kimmeridge Bay.
To be straight with you, this is a tough run. We’re looking at a solid two weeks where the surf just doesn’t line up with clean conditions. The swell shows up at times, but the wind is almost always messing it up. We’ve got a real gap here – from now until the end of the first week of September, the conditions are just poor. There’s no real stand-out session in that first stretch.
We kick off Friday the 28th of August. There’s a small 3 ft swell from the WSW, but a fresh 30 km/h cross-wind has the surface all lumpy and cross-chop. It’s a no-go. That afternoon the wind cranks up to 45 km/h, cross-onshore, with the swell building to 6 ft. The combined energy is moderate at 243, but it’s messy and blown out. Saturday the 29th sees the swell jump to 12 ft in the afternoon with a near gale cross-onshore wind at 50 km/h – that’s a massive 1352 combined energy reading, but it’s an absolute washing machine. Only for the hardcore, and even then, it’s not clean.
Sunday the 30th through to Tuesday the 1st of September offers a little more hope, but the wind stays onshore or cross-shore, keeping the surf lumpy and poor. The water temperature is about average for the time of year. By Tuesday morning the 1st, we finally get a clean window with a light cross-offshore breeze and a tiny 2 ft swell from the WSW, but the combined energy is weak at 73. It’s not really worth paddling out for.
From the 2nd of September, we slip back into small, choppy surf with onshore winds. A small pulse on the 3rd of September with 5 ft swell and moderate cross-shore wind might look okay on paper, but the combined energy is 123 and it’s still cross-chop. The conditions are just not cooperating.
The real quiet spell hits from the 5th of September onward. We’re looking at swells dropping below 1 ft for days on end. The morning of the 5th is clean with a light offshore, but there’s barely a ripple. That pattern holds through the 6th and 7th. There is a small pulse of 4 ft on the 7th of September from the WSW, with a moderate cross-shore wind and combined energy of 107, but it’s still cross-chop.
After that, it’s a long flat spell. From the 8th of September, the swell is consistently under 2 ft, and by the 11th and 12th, it’s practically flat. There’s a tiny 0.3 ft swell on the 12th with a very long period of 13 seconds from the west, but the combined energy is just 6. Not enough to surf.
Honestly, for the next 16 days, there’s not a single session I’d call a standout. The swell and wind just never come together. If you’re itching to get wet, the cleanest windows are the mornings of the 1st and 5th of September, but the swell is tiny. For now, it’s a waiting game. Forecasts can change, but this run looks pretty barren.
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.
