The Lowdown

Alright, this is Rusty, and I’m looking straight at what we’ve got for Kimmeridge Bay over the next couple of weeks. Honestly, it’s a tough run. The whole 16-day window is a real mixed bag, and most of it is just not worth paddling out for. There are long gaps where the surf is junk, and we’ve got to wade through a lot of nothing before anything even gets close to decent.

Right now, starting on Monday the 31st of August, it’s all a write-off. We’ve got a 6 ft swell from the WSW but it’s getting hammered by a strong 22 mph cross-off wind, making it messy. The combined wave energy is moderate at 535, but the conditions are poor. That trend sticks for days. Tuesday the 1st and Wednesday the 2nd are tiny and choppy, with swell barely reaching 2 ft and onshore winds ruining any shape. The water temp is a very unusual 69°F, which is much warmer than normal for this time of year – a proper anomaly of 7° – but that’s the only interesting thing.

We don’t see anything rideable until Monday the 7th of September morning, when a light 6 mph cross-off from the NW cleans up a small 3 ft swell, but it’s weak, with energy at just 34. The afternoon picks up to 6 ft from the SW with a gentler cross-shore wind, and the energy climbs to 189, but it’s still not great. Tuesday the 8th morning is the first real glimmer: a tiny 3 ft swell, clean under a slight NNE breeze, and the wave comment calls it “surfable but ordinary.” It’s the best we’ve seen, but it’s still only a 1/10 quality score internally. The energy is low at 78.

After that, it’s back to poor surf. Wednesday the 9th and Thursday the 10th bring more onshore wind and lumpy conditions. Thursday afternoon shows a brief window of clean 4 ft surf from the SW with a cross-off wind, but the energy is moderate at 155. Still, the conditions are “poor.”

Then there’s a real standout, if you can wait for it. On Monday the 14th of September morning, Kimmeridge Bay gets a solid 8 ft swell from the SW, with a 7-second period. The combined energy is a strong 666, which is proper power. The wind is light and cross-shore at 6 mph, so it could be glassy. Now, 8 ft is big – this is expert territory only. It’s a reef break that is very consistent and exposed to the SW, and the optimum direction matches. It’s the one true standout in the whole run, but it’s for experienced surfers only, and crowds are likely. The afternoon turns choppy again as the wind swings onshore.

After that, Tuesday the 15th is back to small, weak, and onshore. The rest of the week is a bust.

So, to be straight with you: there’s almost nothing good for the first 12 days. The only day that fires is Monday the 14th of September morning, and only if you’re an expert and can handle the size and the crowd. For everyone else, this is a long blank spell. It’s a shame, because the reef can hold a wave, but the winds just aren’t cooperating. If you’re into kitesurfing, some of those windy, choppy days might look more interesting than paddle surfing.

Stay patient. Things can always change.

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.
