The Lowdown
Right then, folks. Rusty here. Let’s have a look at what Kimmeridge Bay’s got cookin’ over the next couple of weeks. Straight up, I’ll be honest with you – it’s a grim stretch for wave riding. There’s a proper blank patch from the start all the way through to the 27th of August. A solid ten days with basically nothing worth paddling out for. The first half of the outlook is dominated by those sloppy, short-period wind swells and a persistent cross-shore wind that just chops everything to bits.
The water’s a fair bit warmer than usual for this time of year, sittin’ at 69°F when I first looked – that’s a significant anomaly, 7°F above normal, so you won’t need a thick wetsuit, but there’s no surf to enjoy it in.
The one tiny glimmer comes near the end of the run. On Thursday morning, the 27th of August, things finally line up for a brief moment. We’ve got a glassy 4ft swell rolling in from the WSW with an 8-second period. The combined energy (318) is moderate, but it’s the glassy calm that’s the real catch here – that’ll give you clean, smooth lines off the reef. It’s the only time in the whole 16-day window that the wind shuts up and the swell shows up with a bit of shape. This is your best bet, but it’s a short-lived dawn patrol window only, as the wind swings onshore by afternoon and wrecks it again.
Other than that, the rest of the second week is a write-off. The 29th and 30th have a bit more size – 5ft to 6ft – but the periods are short and the wind is either cross or onshore, making it a lumpy mess. For a spot that’s very consistent normally, this is a proper dry spell. I wouldn’t bother waxing your board until that Thursday morning session.
Stay patient, and keep an eye 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.
