The Lowdown
Alright folks, Rusty here. Let's be straight with you – looking at the charts for the next couple of weeks, it's a quiet spell for Kimmeridge Bay. This reef break (Dorset) is mostly a no-go for proper surfing, with a whole lot of small, wind-affected slop on the cards. The water is sitting at a very unusual 68°F, which is much warmer than normal for this time of year, but that's small comfort when there's barely a ripple to ride.
Right from the get-go on Sunday the 6th, we're looking at tiny 0.7ft slop with a weak 10 combined swell energy from the WSW. The onshore breeze is just chopping it all up. That sets the tone for the first week. Monday the 7th afternoon sees a jump to 3.3ft of swell from the SW with a very long period of 15 seconds, giving it a moderate combined energy (596). That sounds promising, but a fresh cross-onshore wind at 18 mph ruins the party, making for lumpy conditions. The rest of the week is a mix of small swell and messy winds. Even when the wind cleans up, like on the morning of Wednesday the 9th with a clean cross-off breeze, the swell is only 3.3ft and the period drops to a weak 5 seconds (71 energy). It's just not doing anything.
The second week doesn't offer any relief. From the 14th onwards, we're mostly looking at ankle-snappers under 1.6ft. There are a few moments with longer periods, like the morning of Tuesday the 15th with 0.7ft and a 12-second period, but the wind is onshore. Honestly, for the entire 16-day run, the "poor surf conditions" tag is a constant companion. There's simply no stand-out session for a surfer here. If you're really desperate, the cleanest windows are on the mornings of Wednesday the 16th and Thursday the 17th September, with a clean cross-off breeze and tiny, weak 0.7ft leftovers. It's a long, flat stretch.
Stay patient, the forecasts can always change, but for now, leave the boards in the van.

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.
