The Lowdown
Alright folks, Rusty here. Let's have a look at what Kimmeridge Bay has got cooking for us over the next couple of weeks.
Honestly, straight up, it's a tough outlook for the next week or so. We're looking at a period from now right through until the 7th of September where conditions are pretty grim. There's onshore wind from the southwest, cross-onshore winds, and generally messy, choppy surf. The waves are there, but the quality is just not there. You’ll see the combined swell energy bounce around, with a weak 188 (moderate wave energy) kicking things off on Saturday the 29th, but it’s all rubbish with that onshore breeze.
The best we can realistically hope for in the first week is Monday the 31st of August. The wind swings to a cross-offshore from the WNW, cleaning things up nicely. You’ll have a 6ft swell from the WSW with a period of 8 seconds (combined energy of 488), and while it's not perfect, the clean conditions will make the most of it. The afternoon drops a bit to 5ft but stays clean. It's not a standout by any means, but it's the only real window where you won't be getting blown off your board.
We've got a huge, dead gap from the 1st right through until the 7th of September. Loads of small, weak, cross-onshore slop. There's a tiny flash of hope on Monday the 7th of September afternoon, where the wind goes offshore from the NNE and it’s clean, but the swell is a measly 1ft with a very long 11-second period. That long period will be tough to generate any rideable waves on a beach/reef setup like this, and the combined swell energy of 58 (weak energy) backs that up. Definitely for the longboard or the foil only.
Things get slightly more interesting going into the second week. On Thursday the 10th of September morning, we see a bump in size to 5ft from the SW, period of 5 seconds, and clean conditions with a light offshore. The combined energy is moderate at 113. By the afternoon, it’s up to 7ft from the SW (combined energy of 421), but it's a bit onshore. Friday the 11th holds a 5ft swell from the SW in the morning with light winds.
The only true standout, if you can stretch the definition, might be Sunday the 13th of September morning. It’s glassy out of the WSW with a light breeze and a small 3ft swell (combined energy of 55). It's tiny, but glassy conditions make for a very fun, clean surf on a small day. For a bigger wave, Thursday the 10th afternoon's 7ft is the biggest of the whole run, but it's onshore and messy, making it a bit of a messy challenge only for the experienced crew. The water temperature is currently 69°F, which is much warmer than normal for this time of year by 7°, so you won’t need a thick wetsuit.
Overall, it's a frustrating forecast. The consistent, clean days are few and far between. If you’re desperate, make the most of Monday the 31st of August and keep an eye on that later window around the 10th and 13th of September. It tends not to stay this poor for long, so something better could pop up, but for now, it’s a waiting game.
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.
