The Lowdown
Alright, grab a coffee, let’s have a look at what’s on offer at Kimmeridge Bay.
To be straight with you, this forecast is a tough one. Over the next 16 days, there isn’t a single moment the data points to good, rideable surf here. Right from Friday 11th September, we’ve got a 3ft WSW swell with a 9-second period and a cross-shore wind of 12 mph. The water is sitting at 67°, which is a huge 5° warmer than usual for this time of year – that’s very unusual and will feel like a warm bath, but sadly, the surf quality is rated as poor. The wave energy is moderate at best (212), but the wind just messes things up.
Saturday 12th and Sunday 13th September are similar stories: small, weak swells (2ft to 4ft) with short, choppy periods and cross to cross-onshore winds. The energy drops right off (down to 58 or 64), and it’s lumpy or cross-chop. You wouldn’t paddle out for this.
Monday 14th through to Wednesday 16th September, the swell drops to almost nothing (0.3ft to 2ft), with energy values as low as 7. There’s a brief moment on Tuesday 15th afternoon and Wednesday 16th where the wind goes cross-off and it’s clean, but there’s just no swell to push through. Thursday 17th sees a spike – 5ft from the WSW with a short 5-second period. The energy climbs back up a bit (103-117), but the winds are fresh, and the wave state is either clean but gutless (that short period isn’t giving you any shape) or turning lumpy. It’s really not worth it.
From Friday 18th September through to Monday 21st, it’s back to tiny, weak, and often messy. A bit of a bump on Saturday 19th with 5ft and cross-off winds from the WNW at 22 to 25 mph—those are strong winds. The wave energy hits 126, so there’s some power, but that’s kite-surfing weather, not a day for a paddle board. The conditions are too raw and blown-out for a good surf session here.
Tuesday 22nd and Wednesday 23rd are flat or nearly flat. The last few days, Thursday 24th to Saturday 26th September, show a tiny sliver of something. The swell period gets long on Thursday 24th with a 19-second groundswell from the W, hitting 1ft, and on Friday 25th, a 14-second period, 2ft, with energy of 159 (moderate). But the wind is onshore or cross-onshore. A long-period, clean groundswell on a reef with poor wind just doesn’t work here. It washes out completely.
So, the honest truth? There are no standout days. You’d be waiting a long time – days and days of nothing good. The setup looks far more interesting for kite surfing on those windy, bumpy days than it does for a clean surf. Hang in there, these forecasts can change, but for now, leave the board at home.

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.
