The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for Kimmeridge Bay.

To be honest, it's a pretty grim outlook for the next two weeks. The whole 16-day window is a write-off for anything decent. We’ve got a long stretch of nothing but poor surf conditions, with onshore and cross-shore winds ruining any chance of a clean wave. The water is sitting at 69°F right now, which is *much warmer* than usual for this time of year – that’s a 7°F anomaly, feeling more like a late summer swim than a surf session.

The first real sniff of something surfable doesn't come until Saturday the 12th of September. That morning we see a small 4ft swell from the East, with a light offshore breeze from the NNE. It’s clean, but it’s a short-period 5-second windswell with only 93 units of combined energy – weak stuff. The comment says it’s “surfable but very ordinary”, and I’d agree. That’s it. That’s the one and only moment in the whole period that’s even worth a mention. The afternoon gets ruined by a light cross-onshore wind.

Before that, the only other spot of clean conditions is the morning of Saturday the 5th of September, when an ENE wind gives a cross-offshore breeze, but the swell is a pathetic 0.7ft. Not worth paddling out for.

The rest of the time? It’s all cross-on winds, lumpy chop, and blown-out conditions. By the second week, we’re looking at tiny swells around 0.3ft with fresh onshore winds, so there’s nothing to even get excited about. The setup here is a reef, so it takes a decent swell to work, and with the wind this bad, it’s just a mess.

There’s no standout swell here. No big groundswell, no long period, no magic window. It’s a flat, windy run. For a place like Kimmeridge Bay, that’s a normal blank spell. Forecasts can change, but right now, I’d say leave the board at home.

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.
