The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Kimmeridge Bay. I’ll be honest, the next 16 days are a real mixed bag, and we’ve got a long, quiet spell to get through before anything gets interesting.
The outlook starts with a rough patch. From Wednesday the 2nd right through the weekend, we’ve got a fresh cross-onshore wind and lumpy, poor-quality surf. The swell is there, but it’s choppy and messy. The first few days offer nothing worth paddling out for. Then, we hit a real lull. From Sunday the 6th of September all the way through to Tuesday the 15th of September, the energy just drops off a cliff. It’s a long stretch of tiny, ankle-snapping waves with combined energies barely reaching double digits. You’ll see a few clean mornings with light winds, but the swell is just too small to do anything with. For a week and a half, it’s a flat spell, plain and simple.
The only real glimmer of hope, and it’s a long way off, is on the morning of Friday the 4th of September. We’ve got a 7 ft swell from the WSW, and the wind is a light cross-offshore from the NW. The combined energy is a solid 351, which is a decent push. The swell period is a short 6 seconds though, which means it’ll be a bit crumbly and won’t have the punch of a proper groundswell. For a reef break like Kimmeridge Bay, it’s a window of cleaner conditions, but the short period will keep it from being a classic. It’s the best on offer, but it’s a one-morning stand.
The water temperature is around average for the time of year, so no need to dig out the thickest rubber just yet.
After that Friday morning, it’s back to the small stuff and cross-onshore winds for the rest of the forecast. It’s a tough run, but that’s how it goes sometimes. Forecasts can change, so keep an eye on it.
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.
