The Lowdown
G’day, Rusty here. Look, I’ve scanned the next 16 days for Kimmeridge Bay, and I’m not gonna lie to you – it’s a rough stretch. We’re talking a solid two-week gap of nothing but poor surf conditions. The whole run from Thursday the 20th of August right through to Friday the 4th of September is a write-off. There’s no standout session, no hidden gem, just a whole lot of wind and chop making a mess of things.
Let’s break it down. Thursday and Friday (20th and 21st) are a no-go with cross-shore winds and lumpy, poor surf. The weekend doesn’t get any better – tiny dribbles of swell on the 22nd and 23rd, with onshore winds on the Saturday afternoon. The following week, from the 24th onwards, the wind picks up hard. Fresh to strong breezes whip up a messy cross-chop, and even when the swell tries to push a bit of height (like the 5ft on the 24th morning, or the 5ft on the 26th morning), the wind just ruins it. The combined energy is weak to moderate at best, hitting 177 (moderate) on the 24th morning and 170 (moderate) on the 26th morning, but it’s all cross-shore or onshore junk.
Into the final days of August and the start of September, it’s more of the same. The 30th sees a 7ft swell from the SW, but with a cross-onshore wind and a choppy surface, it’s a messy, lumpy mess. The 31st is similar. After that, the swell fades away to nothing. Even the morning of the 2nd of September, with a glassy clean surface and a slight air, has only 2ft of swell – not enough to paddle for.
The water temp is about average for the time of year, nothing to write home about.
Bottom line: there’s no surf worth chasing. Put the board away, grab a coffee, and wait for the next system. The forecast can change, but right now, it’s a flat and windy wasteland.
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.
