The Lowdown

Alright, let's have a look at what's on offer around Kimmeridge Bay for the next couple of weeks. I'll be straight with you—this is a rough patch for this spot. The whole 16-day window is pretty much a write-off for any decent surf. The first decent little pulse doesn't even show up until the very end, on the morning of the 30th of August.

For the bulk of the period, from the 15th right through to the morning of the 30th, we're staring at a long gap of nothing really worth paddling out for. Day after day it's ankle-biters or just messy, short-period windswell, with the combined energy barely getting out of double digits—most readings are sitting between 2 and 98 units of energy—which is basically flat or anaemic. The winds aren't doing us any favours either; it's mostly cross-shore or onshore, often fresh to strong, keeping the surface lumpy and chopped up.

Right at the tail end, on Sunday morning, the 30th of August, we finally see a pulse of something that might get your attention. The swell pushes up to about 4ft from the WSW, and the combined energy jumps to 61 units—still only moderate, but a step up. What really makes this one stand out, though, is the clean, offshore wind from the NNW at 15 mph. That will groom the reef nicely. It's a groundswell with a period of only 5 seconds, so it'll be a bit weaker and less organised than you'd hope, but for a spot that's been dead for two weeks, it's the only chance to get a few reasonable waves on a clean face. The water temp is about average for this time of year, so no drama there.

Kimmeridge Bay is a reef break that's very consistent and fairly exposed to the SW, so when there's swell, it can work. But for this window, the 30th is the only real standout—and even then, keep your expectations low. It's surfable but very ordinary, by the numbers.

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.
