The Lowdown
Right then, let’s have a look at what’s on the cards for Kimmeridge Bay over the next couple of weeks.
Honestly, it’s a pretty grim stretch ahead. We’ve got a long, dry spell with hardly any surf worth getting wet for. From now through to the 23rd of August, it’s all tiny, weak, and messy – barely a ripple. You’re looking at a solid week and a half of flat, poor conditions where the wave energy is just pathetic, often below 24 (combined energy). The wind’s all over the place, too, mostly cross or cross-on, and even when it goes offshore it’s on tiny surf. There’s nothing to recommend here; it’s a proper blank run.
Then, out of nowhere, we get a glimmer on Monday the 24th of August. The morning brings the first proper pulse of energy, with a 5ft swell from the SW, and here’s the kicker – it’s glassy. Absolutely no wind. That’s a rare treat for Kimmeridge. The water’s also running much warmer than normal for this time of year, which is a bonus. The wave energy is moderate, at 106, and while the conditions are only described as “surfable,” that glassy surface will make it look a whole lot better than anything else we’ve seen.
The catch is, this swell is short-period, only 5 seconds, so it’s not got a lot of punch. It’ll be a bit crumbly and soft on the face. Still, for a reef break that’s very consistent, it’ll be clean and user-friendly for intermediate surfers. Keep in mind, though, that it often gets crowded here, so expect company.
The afternoon of the 24th sees the swell bump up to 6ft with stronger energy (202), but the wind swings onshore from the S, and the conditions turn poor. That window is really just that Monday morning.
After that, it’s back to the doldrums. The 25th onwards is all small, weak, and choppy again, with nothing worth paddling out for.
So, if you’re desperate, the standout is Monday morning, the 24th of August at Kimmeridge Bay. It’s the only real chance of a session. It’s not going to be epic, but after all that flatness, a clean, glassy 5ft wave will feel like a luxury.

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.
