The Lowdown
Alright, folks. Rusty here. Let’s have a look at what’s on the cards for Kimmeridge Bay.
To be straight with you, the next sixteen days are a write-off. There’s nothing worth paddling out for. The first surfable day that even gets a small whisper of potential is Friday the 11th of September, but even that’s a tough one. The swell is tiny and the combined energy is a weak 377, which sounds bigger than it is for a reef. It'll be walled out or just not enough oomph.
The rest of the run is a long, sad gap. Day after day of poor surf conditions, with winds mostly cross or cross-on, and the swell heights barely scraping 3 ft. The water is sitting at 68°F, which is a whopping 6°F warmer than normal for this time of year – that’s very unusual, but it won’t help the waves.
Honestly, there’s no standout. There’s no best on offer. The consistency is very consistent, but consistently poor. For a spot like this, a blank run is more normal than you’d hope. If you’re desperate, the only sliver of a chance is Friday morning the 11th, with a 5 ft swell from the WSW and a 9-second period, and cross-off winds from the WNW at 12 mph. The combined energy is 377, so it’s there, but it’s a marginal call. Even then, it’s more of a “maybe if you’re bored” than a real session.
Hold tight, check back in a week. The forecasts can change, and it tends not to stay this poor for long.
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.
