The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Kimmeridge Bay over the next couple of weeks. I’ll be straight with you – it’s a tough stretch.
The honest truth is there’s not a single day in this 16-day window that’s got a proper surfable wave. The forecast is a long, flat, and choppy run. We’ve got a bit of a gap right from the start: persistent poor conditions with next to no swell energy. From the 7th of August right through to the 22nd of August, it’s all “poor surf conditions” – a real bummer. The combined energy values are tiny, mostly well under 100 (e.g. 6, 2, 4, 8), meaning there’s virtually no oomph in the water. For a spot like Kimmeridge Bay, which is a reef break that can handle a bit of swell, this is a dry spell.
The water temperature is a standout feature though, sitting at 68°F on the 7th of August. That’s a whopping 6°F warmer than normal for this time of year, so the water is feeling much warmer than usual. That’s about the only positive.
We do get a tiny bump in energy on the 19th of August, with the combined energy climbing to 115, but even then, the wave comment is still “poor surf conditions.” The swell direction is from the WSW, which is a decent direction for this reef, but the swell height is only 4 ft, and it’s paired with onshore winds on the 19th afternoon. The morning of the 19th does have light cross-offshore breezes and clean conditions, but with a short period of 6 seconds, it’s weak and disorganised. It’s not enough to get excited about.
Honestly, if you’re desperate for a paddle, the cleanest looking windows are the odd mornings with light offshore winds, like the 10th of August, the 13th of August, and the 14th of August, but the swell is barely a ripple. The 17th of August morning is glassy, but with a 1 ft swell and 4-second period, you’re looking at a lake. This setup is more interesting for a kite surfer than a paddle surfer, given the frequent cross-shore winds and lack of rideable waves.
It’s a frustrating outlook, but for this area, a blank run like this is not unusual. Forecasts can change, but for now, keep the boards in the van.
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.
