The Lowdown
G’day, Rusty here. Look, I’m gonna be straight with you – the next couple of weeks at Kimmeridge Bay are a tough watch. We’ve got a long, long stretch of poor surf conditions, with a mix of onshore winds and weak, messy swell. The only real light at the end of the tunnel doesn’t show up until Wednesday the 16th, and even then, it’s a big-wave session for the experts only.
Right now, through Sunday and Monday the 6th and 7th, it’s all cross-onshore winds with tiny, short-period swell. The combined energy is weak (12) on Sunday, and while Monday morning has a touch of cleaner wind, the swell is only 1 ft – it’s barely a ripple. The water temp is sitting at 68 °F, which is a whopping 6 °F warmer than normal for this time of year – that’s very unusual for here.
We then slide into a long, frustrating gap. From Tuesday the 8th all the way through to the morning of Tuesday the 15th, the scores are absolutely flat. The winds are mostly cross-off or clean, but the swell is pathetic – heights bouncing between 0.7 ft and 5 ft, with period often under 8 seconds. The combined energy on the 15th drops to just 27 – that’s a lake, not a surf break. There’s a brief moment on the morning of Sunday the 13th with light offshore winds, a 2 ft swell, and a hint of “surfable waves,” but it’s so ordinary it’s barely worth a paddle.
Then, finally, on Wednesday, September 16th, we get a pulse. The morning brings a 8 ft swell from the southwest, with a 7-second period and a clean, cross-off wind from the NNW. The combined energy jumps to 553 – that’s moderate-to-strong energy. This is the standout of the whole run, but don’t kid yourself, this is for experts only. That size is too big for beginners, and the 7-second period means it’s going to be a bit walled-up and tricky on the reef. The afternoon is a touch smaller but still 8 ft, with a cross-shore wind and a combined energy of 730 – even more punch. Thursday the 17th drops back to 5 ft, and the wind goes light, but it’s a cross-shore breeze, so it won’t be as clean.
Honestly, for the first two weeks, there’s nothing to get excited about. If you’re a kite surfer, the fresh cross-onshore winds and 4 ft to 6 ft swell on the 10th, 12th, and 14th might look more interesting than a paddle session. But for the rest of us, wait for the 16th, bring your biggest board, and be ready for a clean, powerful, expert-only session.
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.
