The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Kimmeridge Bay over the next couple of weeks. I gotta be straight with you – it’s a tough read. This stretch of coast is seeing a whole lot of nothing for days on end, and when the swell does show, the wind’s got other plans. We’re looking at a long, barren run until we finally get a window of hope right at the very end of the 16-day window.
The first bit of surfable energy doesn't even appear for over two weeks. From now until the 3rd of September, the wave comment is consistently "poor surf conditions" with scores of zero. There's a brief pulse of moderate energy on the 27th of August, hitting 125 (moderate wave energy) in the morning, but it's accompanied by a cross-onshore wind, leaving it lumpy and choppy. Not one for the logbook. The 29th of August sees the biggest numbers, with the combined energy climbing into the strong category at 527 on Saturday morning and even 1147 by the afternoon, with swell hitting 10ft and a period of 8 seconds. But that’s a monster cross-on wind from the southwest at 25 mph, making it a messy, howling mess. That’s kite-surfing territory, not paddle surfing. The swell is too big for beginners and only really for experts, but the conditions are so poor it’s not even worth the paddle out for them.
The only true standout in this whole 16-day forecast is on the 4th of September. That Friday morning, things finally click. We get a clean 6ft swell from the SW, with a period of 8 seconds. The combined energy is a solid 368 (strong wave energy). The wind shifts offshore from the NNE at 12 mph, promising clean, workable faces. The water temp on the 20th of August was at 69°F – a massive 7° warmer than average for this time of year. That's very unusual, so by the 4th of September we can expect it to still feel warm for an autumn session. That Friday morning is the only time the report says "expect good surf conditions" – a true blip of hope in an otherwise bleak outlook. If you're chasing anything, that’s your window. For the rest of it, I’d save the wax and watch the forecast change. It can’t stay this poor forever.
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.
