The Lowdown
Alright folks, Rusty here. Let's have a look at what Kimmeridge Bay has in store for us over the next couple of weeks. I'll be straight with you – it’s a tough outlook. This is a reef setup, and it's very consistent, but the conditions just aren't lining up for a good paddle.
The water is sitting at 69° at the start, which is much warmer than normal for this time of year – a solid 7° above average. That’s pretty unusual.
We start off on Monday the 24th of August with absolutely nothing doing. The swell is tiny, and we've got a strong cross-shore wind making a mess of things. Tuesday the 25th sees a bit of a bump in size Tuesday morning, with a 5ft swell from the east and a clean wind state, but the period is a short 6 seconds, so it’s going to be weak and bumpy. The energy reading is 141, which is moderate, but that short period means weak, mushy waves.
Wednesday the 26th has the wind swinging offshore light, but the swell drops right out. It’s flat. Through the rest of the week and into the start of September, we are stuck with small, weak swells and persistent cross-onshore winds. The energy is mostly in the double digits. There’s a slight glimmer on Wednesday the 2nd of September morning, with a clean 4ft swell and a cross-offshore breeze, but the period is only 5 seconds. It’s surfable, but very ordinary.
The real story here is the huge spike in energy around Monday the 7th of September. We’re looking at a 8ft swell from the southwest with a very long period of 19 seconds and energy readings hitting a massive 6,357. That is serious groundswell. The size is pushing beyond intermediate territory and into expert-only zone. The wind is cross-shore, which is not ideal, and the period is so long (over 15 seconds) that this reef break is going to be tricky; these long-period swells tend to unload fast and close out on a setup like this. It’s a powerful but dangerous proposition.
Straight after that, Tuesday the 8th of September morning looks interesting. The swell holds at 8ft from the WSW, but the period drops to a more manageable 7 seconds. The wind goes cross-offshore from the northwest, so it will be clean. The energy is still a strong 668. This is probably the best window for a surfer who knows what they are doing, but even then, that size is only for experienced crew. There’s a chance of crowds here, as it's often busy.
The final week sees the swell drop off and the winds go back to being messy. There is no standout, perfect day in this forecast. The best bet for experts is the morning of the 8th of September, but for everyone else, it’s a waiting game.
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.
