The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. For the first two weeks there’s pretty much nothing doing. We’re looking at a long, dry gap from now until the start of September. The swell is tiny, the wind is all over the shop, and the sea just isn’t playing ball. The energy is weak, and conditions are mostly a write-off for a paddle.
The only real glimmer on the horizon doesn’t show up until the 4th of September. We’ve got a bit of a pulse coming through for Kimmeridge Bay. It’s a reef break, very consistent, and it likes a SW swell. On Friday the 4th, the morning sees a solid 6ft swell from the SW, with a period of 6 seconds. The combined energy is strong at 306, and we’ve got a clean offshore wind from the North at 19 mph. The afternoon looks even better – same 6ft swell, still from the SW, but the wind drops to a moderate 12 mph offshore from the North, making for clean, peeling waves. The energy is still strong at 304. This is the standout. It’s a couple of weeks out, so keep an eye on it, but this is the one to pencil in. It’s an intermediate spot, so if you’re a beginner, that 6ft might be a bit much. The water is going to be about normal for the time of year, no major anomalies to report.
Before that, there’s a brief moment on the 3rd of September with a 4ft to 4ft swell from the SW and a clean offshore wind, but the energy is moderate and the quality is just okay. Nothing to get too excited about.
So, in short: a long, blank stretch, then a clear favourite on the 4th of September. Keep your powder dry until then.

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.
