The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Kimmeridge Bay. Straight up, I gotta be honest with you, the next week and a half is looking pretty grim. We've got a solid run of poor surf conditions with messy winds and weak swell, so don't bother waxing up just yet. The real action, if you can call it that, doesn't even start to whisper until Monday the 21st of September, and even then it's only just surfable.
Let's break it down. From Friday the 11th right through until Sunday the 20th, it's a write-off. We're talking predominantly cross-shore and cross-onshore winds from the west and southwest, gusting up to 18 or 22 mph at times. The swell is all over the place, mostly short-period junk under 8 seconds, and the combined wave energy is weak, often below 100. It's just not worth getting wet for. There's a tiny window Tuesday afternoon the 15th where the wind swings cross-off and cleans it up, but with a weak 4ft swell and a short period, it's a long shot.
The first real glimmer comes Monday the 21st of September. Morning sees a moderate offshore breeze from the NNE, finally giving us some clean lines on a 3ft swell from the west. The energy is still weak at 70, and the period is short at 5 seconds, so it's not going to be pumping, but it's surfable. Afternoon cleans up even more with a lighter cross-off. This is your best bet for a grovel session if you're desperate.
Tuesday the 22nd is tiny, with a 0.7ft, 13-second groundswell that has plenty of period but just not enough height to do anything with.
Then, Wednesday the 23rd of September morning looks interesting on paper – a solid 7ft swell from the WSW with moderate energy at 342. But the wind is light and variable cross-shore, and the report calls it "marginal." Still, if you're an experienced surfer, this could be the most size you'll see, but it's going to be a bumpy, chop-infested mess.
After that, Thursday the 24th and Friday the 25th offer some cleaner, surfable waves in the 5ft to 6ft range from the SW, with light cross-off winds. The period is still short on these, around 6 seconds, so expect little, crumbly waves. The energy is moderate, hitting 145 on Thursday and 175 on Friday. Friday morning looks the pick with clean conditions and a light NE breeze.
Saturday the 26th of September is a bit of a tease; the swell is there at 5ft from the southwest, but the wind is cross-off and clean in the morning. It's a shame the wave energy (165) and short period suggest it'll be a bit ordinary again.
Looking at the whole picture, Kimmeridge Bay doesn't have a true standout. If I had to pick one, it'd be Friday the 25th of September morning. It's the most consistent option with a 5ft SW swell, a clean cross-off wind from the NE, and moderate energy. It's not going to be classic, but it's the best of a bad bunch. Everything else is either too small, too messy, or too far off.
Remember, this is a reef break that's very consistent and can get busy, so if you do head out on that Friday morning, expect company. The water temp is pretty much what you'd expect for this time of year, nothing unusual there. Until the 21st, save your energy.
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.
