The Lowdown
Alright folks, Rusty here. Let’s have a look at what Kimmeridge Bay’s got cooking for us over the next couple of weeks. I’ll be straight with you – it’s a tough one.
Right off the bat, the pattern is flat and lifeless. We’re looking at a long, dry stretch with barely a ripple. The first real chance of anything rideable doesn’t show up until Monday, September 7th, and even then, it’s not great. For the first few days, it’s all tiny waves and poor conditions. The water temp is sitting at 68°, which is a whopping 6° warmer than usual for this time of year – that’s very unusual, and honestly, it feels like a warm bath out there.
The first potential session is Monday, September 7th afternoon. The swell bumps up to 4ft, coming from the WSW, but it’s a short period windswell at 13 seconds. The real problem is the wind: a fresh 19 mph cross-onshore from the WSW, making it a lumpy, messy mess. The combined energy is moderate (472), but the quality is poor. Tuesday morning, September 8th, is cleaner with cross-offshore winds, but the swell is already dropping and the period is a pathetic 5 seconds. It’s just not going to be any fun.
You’ll see a few mornings with glassy or clean conditions, like Thursday, September 10th morning with a glassy 1ft, but the swell energy is so weak (21) it’s barely a ripple. Then on Friday, September 11th, we get a spike of 5ft from the SW, but it’s accompanied by a strong 25 mph cross-onshore wind. That’s a messy, blown-out mess; only for the hardcore or maybe the kite surfers. The swell energy is strong (230) but the wind is a deal-breaker.
After that, it’s back to tiny, weak swells with periods all over the place. We see a few clean, glassy mornings in the second week, like on Monday, September 14th and Tuesday, September 15th, but the swell is just 0.3ft to 0.7ft. There’s simply no power. The only standout is that the wind is occasionally perfect, but you need more than just a nice breeze.
Honestly, there isn’t a single standout session in this whole 16-day window. The best of a bad bunch would be the clean mornings on Tuesday, September 8th or Thursday, September 10th, but you’d be chasing ankle-biters. The bigger pulses on the 7th and 11th are just too windy. For a spot that’s very consistent and a reef setup, this is a real blank run. It’s just one of those periods where the surf gods are taking a holiday. Forecasts can change, but right now, it’s looking like a long wait.
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.
