The Lowdown

Right then, let's have a look at what’s on the cards for Kimmeridge Bay. I’ve got to be straight with you – it’s a tough outlook. We’re looking at a 16-day window starting now, but you’re going to have to be patient because the first real chance of anything decent doesn’t show up for a while. The water here is sitting at 69°, which is much warmer than normal for this time of year, so at least you won’t be cold while you’re waiting.

We’ve got a long, frustrating stretch of small, choppy, and blown-out conditions to start. Wednesday the 27th and Thursday the 28th are out. The swell is tiny, the wind is onshore or cross-onshore, and the periods are short. Friday the 28th afternoon sees the swell jump to 8 ft from the SW with a period of 7 seconds, but the wind is a strong 28 mph cross-onshore, making it an absolute mess. The combined swell energy is ramping up to 547, so there’s power there, but it’s not for paddling. With that kind of wind and a beach/reef setup, this looks more interesting for kite surfing than paddle surfing.

Saturday the 29th is just as bad, with a near gale blowing. The swell hits 10 ft from the SW, but the conditions are blown out. Sunday the 30th is still lumpy and messy, and the drop in quality continues right through the first week of September. The best I can see in that first week is a small window on Saturday the 5th of September. On Saturday morning the 5th, we get a clean spell with a 2 ft WSW swell, a period of 11 seconds, and a light offshore from the NW at 9 mph. The combined energy is 134, so it’s weak. It’s a small, clean, long-period groundswell, which is better suited to a reef like Kimmeridge Bay than a beach break, but it’s really tiny. It’s the only time the wind looks good, but you’ll be hunting for anything rideable.

After that, it’s back to small and messy until the 10th of September. On Thursday morning the 10th, we see a 5 ft SW swell with a period of 5 seconds. The wind is a clean cross-offshore from the NE at 16 mph, and the wave comment says “clean”. The energy is 115. It’s a short-period swell, so the shape won’t be epic, but it’s the cleanest we’ve seen. The afternoon gets a bit bigger at 6 ft from the SW with a 6-second period, and lighter winds. Given the conditions, Thursday the 10th of September is the standout. It’s not perfect, but with clean winds and a bit of size, it’s the best option in this entire outlook. Expect crowds here as it’s often busy.

So, to sum it up: sit tight for a long wait. The first week is a write-off. Saturday the 5th of September offers a clean but tiny window, and Thursday the 10th of September is your best bet with clean, rideable waves at Kimmeridge Bay. The forecasts can change, so keep an eye on it, but for now, it’s a patience game.

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.
