The Lowdown
Alright folks, Rusty here. I've had a look at the long-range for our stretch of coast, and it’s a tough one to deliver. We’ve got a solid 16-day window, but it is looking like a whole lot of nothing for surfable waves. I’m not going to lie to you, it’s going to be a test of patience.
For the entire forecast, we are locked onto Kimmeridge Bay. It's a reef break that needs a good swell, and that’s exactly what’s missing. The first ten days are basically a dead loss. We’re looking at tiny, weak swells with poor conditions, and wave energy readings are in the dumps, consistently below 100 and often in the teens. The water is a balmy 68°F, which is a full 6°F warmer than it should be this time of year. That is very unusual. It's a real oddity, but it doesn't help us get a wave.
There’s a slight pulse on the afternoon of September 11th when the period pushes to 9 seconds and the energy jumps to 204, but it’s still written up as poor surf. Not worth the drive. The next day, the 12th, has some size at 5ft, but it's lumpy and blown out. That’s a kitesurfing wind, not a surfing wind.
The middle part of the month is terrible. We're talking about waves screaming down to 0.3ft. There’s a moment on the morning of the 16th with clean offshore winds, but the swell is a non-existent 0.7ft. You would need a surfboard the size of a door just to catch a ripple.
We finally get a change in swell direction to the east around the 20th, but it’s not backed by any size or period. The only “surfable” nod in the whole forecast comes on the morning of September 21st with 4ft of east swell. But here’s the kicker: the period is a woeful 5 seconds. That’s short-period windswell, not real groundswell. It’ll be lumpy and have no push. The 23rd might see 4ft, but the cross-shore wind will chop it to pieces.
So, what’s the call? There is no call. There are no standout days here. The clean days have no waves, and the days with a little bit of size are going to be messy. It’s a grim outlook. We might get lucky if a forecast changes, but as it stands, this is about as barren a stretch as I’ve seen in a while.
Keep the boards waxed and the hopes low. This is Rusty, out.

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.
