The Lowdown
Alright, surfers, Rusty here. Let’s break this down: it’s a rough one.
We’re talking about Kimmeridge Bay, a reef break that’s usually consistent, but we’re in for a long dry spell. The first real chance to get wet doesn’t show up until the 2nd of September, so you’ve got over a week of flat, junky, or straight-up ugly conditions. Water temp on the 24th is 69°F, which is a wild 7°F warmer than normal – that’s a real anomaly, feels like a summer holiday.
The first week is a total wash. From the 24th of August through the 1st of September, it’s all tiny surf, messy cross-shore winds, or strong onshore slop. Winds are often in the 18-25 mph range, just tearing the surface to bits. A few days see a bit of swell, but the wind is all wrong, leaving it choppy and lumpy. Not worth the effort.
There’s one brief glimmer on the 2nd of September. Wednesday morning, the wind swings to the NNW at a gentle 9 mph, giving us a clean cross-offshore breeze. The swell is 5 ft from the SW, but the energy is weak (98). It’s described as "surfable waves but very ordinary conditions." That’s the best we’ve got, and it’s not saying much. The Wednesday afternoon shows a bigger 7 ft swell from the WSW, but the wind is light and cross-shore, and the conditions are "marginal." That size is big enough to be a handful for beginners, and with weak energy, it’s going to be fat and slow.
After that, the 3rd of September drops right back to flat, and we’re back to poor conditions. The 8th of September shows a massive spike in energy, with a reading of 1060 on Tuesday morning, driven by a 4 ft swell from the SW with a very long period of 19 seconds. That’s a proper groundswell, but it’s coming with a fresh onshore wind from the south, which will ruin it. A period over 15 seconds like that means it’ll break straight and fast, better for a point or reef, but with that wind, it’s a no-go for a clean session.
Honestly, there’s no standout. The best is the morning of the 2nd of September, but it’s a stretch to call it good. It’s a waiting game. Forecasts can change, but right now, it’s a lean patch.
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.
Kimmeridge Bay is 18 km (11 miles) from the city of Poole. If you plan a holiday in South Coast of England, look for hotels and other accommodation in Poole. Poole has rooms for a wide range of budgets as well as car hire and transport links.
