The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Kimmeridge Bay.
First off, I gotta be straight with you – it's a lean stretch ahead. We're looking at a solid run of days with just not much to write home about. The first real chance of anything worth paddling out for doesn't show up until Tuesday the 18th of August. So, from now until then, it's flat or sloppy. A whole lot of tiny, wind-affected waves that are just not worth your time. The gap is over a week long, so don't hold your breath.
Now, for the one bright spot. Tuesday the 18th of August, the morning session is the only thing on the menu that gets a nod. We've got a clean 4ft swell rolling in from the SW. The wind is light and cross-off from the WNW, which is a major positive – it's going to be clean out there. The water temp is about average for the time of year. The combined energy is moderate at 67. It's surfable, but it's not pumping. The swell period is a short 5 seconds, so it'll be a bit weak and won't have much push. It's an ordinary morning, but it's the only game in town.
After that, the wind cranks up again on the afternoon, and it's back to poor conditions. The rest of the outlook is a write-off with onshore winds and messy, lumpy surf. The wind finally cleans up again on Saturday the 22nd of August, with a 4ft SW swell and a fresh cross-off NW wind, but it's still only rated as "poor surf conditions". The energy is strong at 219, but the wind and swell combo just don't line up for a quality ride at this reef.
So, bottom line: if you're desperate, you've got one morning on the 18th. Otherwise, it's a long wait. Kimmeridge Bay is a consistent reef that can handle a decent swell, but the wind just isn't playing ball this time around.
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.
