The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got coming our way over the next couple of weeks at Kimmeridge Bay.
Right off the bat, I’ve gotta be straight with you – it’s a tough outlook. The first solid window of surf we see kicks off on the morning of Friday the 4th, but even then, it’s not the cleanest picture. The water is running at 68°F, which is much warmer than normal for this time of year – that’s a weird one for sure, a good 6°F above where we should be.
The main event, as far as it goes, looks to be that Friday morning (September 4th). We’ve got a 7ft swell rolling in from the WSW, with a moderate cross-offshore breeze out of the WNW. That combo should clean things up nicely, giving us some fun, clean lines on the reef. The combined energy is moderate (356). It’s a solid, intermediate-friendly size, but with that 7-second period, it’s a bit of a windswell – it’ll be peaky and a bit disorganised, but still fun on the high tide.
The rest of that first week is a struggle. The swell drops right off into Saturday, down to 2ft, and we’re dealing with a lot of cross-shore and cross-onshore chop. Nothing really worth paddling out for until maybe the morning of Wednesday the 9th. That morning shows another pulse of 6ft from the WSW, with clean conditions thanks to a cross-offshore WNW breeze, and moderate combined energy (298). It’s a similar story to the Friday before – a bit short in period at 7 seconds, so don’t expect any groundswell walls, but it’ll be rideable and clean for those who want a paddle.
After that, the second week gets real quiet. From the 10th of September right through to the 17th, we’re looking at tiny waves, mostly under 2ft, with a lot of messy wind and chop. There’s a long-period pulse showing up around the 14th and 15th (10-12 seconds), but the swell height is barely 1.0ft – it’s all just a rumble, no push. Then on the morning of Thursday the 17th, we get a weird little fluke: a glassy 3ft from the ESE with barely a breath of wind. That’s about as clean as it gets, but it’s tiny and the period is short at 5 seconds. It’s a looker, not a surfer.
Honestly, there’s no standout stunner in this run. The two clean mornings (4th and 9th) are the best on offer, with the Friday the 4th being the pick of the bunch for a bit of size and shape. But for most of the 16 days, the Bay is either flat or chopped out. It’s a long blank spell after the 9th. Keep your eyes on the charts – it tends not to stay this poor for long.
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.
