The Lowdown

Right, Rusty here again. Let’s talk Kimmeridge Bay in proper terms.

First week is a dead loss. From Monday the 10th of August, there’s nothing worth getting wet for – just a long, flat spell with bad wind. The water is 68°F, which is way warmer than usual for August. Weird.

The wind is mostly side or sideshore, kicking up chop. Even when we get a glassy moment on the evening of Wednesday the 19th of August, the swell is only 0.7ft with almost no energy. Not worth looking at.

Things finally change on Saturday the 22nd of August. The morning shows 6ft from the WSW at 6 seconds. The combined energy is 266 – that’s moderate grunt. Wind is cross-offshore out of the NW at 12 mph, so the surface should be tidy. But it’s still not a good wave. That afternoon turns side-off and messy.

The best bet is Sunday the 23rd of August. The morning brings 4ft from the west, period of 5 seconds, with a clean offshore wind from the NNE at 6 mph. Combined energy is 92 – weak but workable. It’s the cleanest window across the whole 16 days. It’s just “ordinary” at best, but with the offshore wind, it’s the only one you’d even consider. Crowds are common here, so you won’t be alone.

After that, it fizzles into tiny, long-period slop (15 seconds on the 24th) that won’t wrap into the reef. By the 25th, it’s tiny again.

If you’ve got to go, make it Sunday morning the 23rd of August. Otherwise, keep the board in the car.

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.
