The Lowdown
Right then, let’s have a look at what we’ve got for Kimmeridge Bay. Straight up, I’ve gotta be honest with you – this is a tough one. The whole sixteen-day window is looking pretty grim, with nothing that I’d call a proper surf recommendation. Every single session is flagged as poor surf conditions, and the scores reflect that. The water is a notably warm 68°F for this time of year, about 6°F warmer than normal, which is very unusual, but that’s about the only interesting thing going on.
We’re looking at a long, barren run here. From the start of the period on Saturday the 5th, right through to the final record on Sunday the 20th, there’s just no wave energy worth paddling for. The combined swell energy is weak, with most values below 100, and even the strongest pulse – Monday the 7th afternoon with 427 – is paired with a nasty 22 mph cross-onshore wind that’ll have it lumpy and blown out. Not a chance.
The swell itself is tiny, rarely pushing above 3 ft, and the directions are all over the place. Most of the period is plagued by onshore or cross-shore winds, with only a few fleeting moments of glassy or offshore conditions. For instance, Thursday morning the 10th goes glassy, but the swell is a measly 1 ft with a short period of 7 seconds – just not enough to break properly. Saturday the 12th has clean offshore winds, but again, only 2 ft of swell. It’s frustrating.
For the second week, the story doesn’t change. From Monday the 14th onwards, we’re seeing even less energy, with combined values dropping into single digits. The swell is basically non-existent, and even when we get a glassy morning on Saturday the 19th, there’s only 0.7 ft of swell. It’s a desert.
Honestly, there’s nothing to get excited about here. If you’re desperate, the cleanest windows are the Thursday morning glass-off on the 10th, or the offshore mornings on Saturday the 12th, but you’ll be scratching for waves. This area can go flat like this, so it’s not a huge surprise. Keep an eye on the charts, because it tends not to stay this poor forever.

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.
