The Lowdown

Alright, folks, Rusty here. Let's have a look at what's on the cards for us at Kimmeridge Bay. I've got to be straight with you, it's a tough read this time around.

We're looking at a 16-day window that kicks off on the 11th of September, but honestly, there's not a single day in the whole period that I'd call a proper go-out. The waves that do show up are tiny, the wind is often messy, and the whole stretch is marked as "poor surf conditions" with a score of zero across the board. The main issue is that whenever there's a bit of height, the wind is cross or onshore, and when the wind goes offshore, the swell drops right out. You'll see this pattern right from Friday the 11th through to the 14th of September, where the swell sits at 1.6 ft to 4.3 ft but is riddled with cross-shore and onshore breezes, making it lumpy and chop. We also get a bunch of very short-period swells down to 4 or 5 seconds, which just won't produce any meaningful shape.

There’s a long gap of tiny, unrideable surf from the 17th of September right through to the 24th of September, with swell heights mostly 0.3 ft. It’s dead. The combined wave energy during that period is often in single digits, like 8 or 3 (very weak energy), confirming there's nothing to work with.

The only glimmer of something different comes right at the end, on the 25th of September. We see a bit of a bump from the WSW at 1.3 ft, but the period is long at 14 seconds, and it’s coming straight from the SW, which is close to the optimum direction for this spot (SW). The problem is the wind is a fresh cross-onshore at 22 mph, so it’ll be lumpy. The combined energy is 44 (weak). Not a goer.

Then on the 26th of September, the wind finally turns offshore from the WNW (22 mph), giving clean conditions. But the swell is a pathetic 0.3 ft from the SW with an 11-second period and a combined energy of just 6 (very weak). It’s clean, but there’s nothing to ride.

So, what do I tell you? There's no standout, no best on offer. This is just one of those blank runs for Kimmeridge. The water temperature is 66.9°F and a whopping 5.4°F warmer than normal, which is very unusual for this time of year, so at least it feels like a warm bath out there. But for a surf, you're better off staying home.

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.
