The Lowdown
Right then, let’s have a look at what’s on offer for Kimmeridge Bay. Straight off the bat, I gotta be honest with you, it’s a tough outlook. We’re looking at a long, dry spell with no real surf to speak of for the entire 16-day window. Every single session across the board is scoring a flat zero for surf quality, so there’s nothing to get excited about. The water temp is about average for the time of year, so no surprises there.
The whole period is a washout. From Saturday the 5th to Sunday the 20th of September, every day shows either tiny, weak swell or messy, blown-out conditions. The combined wave energy is weak throughout, often reading in the low double or single digits, like 28 (moderate cross-onshore and choppy) or 11, which is barely a ripple. Even when the swell bumps up a bit, the wind always seems to spoil it.
A few sessions look clean on the surface, like Monday morning the 7th with a cross-off breeze and 2 ft of swell from the SW, but with a combined energy of only 126, it’s just not enough to push through. The same goes for Saturday morning the 12th – we get a glassy 2 ft from the W, but it’s short period at 5 seconds, and the energy is only 25. It might look pretty, but there’s no power behind it. For a reef break like this, that’s just not going to cut it.
It’s a real shame, because Kimmeridge can fire when the swell direction lines up with its optimum SW. But with the consistent lack of size and quality, and winds that are either too strong or from the wrong direction, it’s a blank run. For an area where the consistency is usually very high, this is a poor stretch of weather and sea.
Stay patient. Things can change, but for now, keep the board 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.
