The Lowdown
Alright folks, Rusty here. Let me be straight with you about this stretch of coast. We’ve got a lumpy, messy picture ahead, and I’m not going to sugarcoat it.
Kimmeridge Bay is a reef setup that's very consistent and usually fairly exposed to the SW, which is its optimum direction. The water is sitting at 68°, which is a whopping 6° warmer than normal for this time of year. That's a weird one.
The problem is, for the entire 16-day window, every single day is marked as "poor surf conditions." There’s never a day where the score rises above a zero. The combined energy starts off with a moderate 721 on Monday the 7th, with a 4ft WSW swell at 13 seconds, but it’s ruined by a fresh 19 mph cross-on wind. That’s just lumpy, blown-out junk.
After that, the swell drops off a cliff. Tuesday the 8th through the end of the run is a graveyard of tiny waves, flat spells, and onshore or cross-shore winds. Even the clean days with offshore flow (like Wednesday morning the 9th with a 12 mph NW cross-off) only have a tiny 3ft of weak, short period swell at 8 seconds. The energy values are all in the double digits or lower, which is barely a ripple. A cleaner day on the 16th has a 0.3ft swell, and the 17th brings a new 3ft ESE swell, but it’s a short period 5 seconds and comes with a cross-on wind again.
This is a brutal run. There are no standouts, no hidden gems. The reef isn't the problem—the weather and lack of proper swell are. For a spot that’s very consistent, this is a real dud. It’s one of those blank runs where you just have to wait for the next frontal system to change the charts. Forecasts can change, sure, but right now, I’d leave the board in the car.
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.
Kimmeridge Bay is 18 km (11 miles) from the city of Poole. If you plan a holiday in South Coast of England, look for hotels and other accommodation in Poole. Poole has rooms for a wide range of budgets as well as car hire and transport links.
