The Lowdown

Alright, folks, Rusty here. Let’s have a look at what Kimmeridge Bay has got cooking for us over the next couple of weeks.

Straight off the bat, I gotta be honest with you – the next week and a half is a real mixed bag, and mostly a quiet one. We’re looking at a long, dry spell with very little to get excited about. From Saturday the 22nd right through to the end of the month, the surf is pretty much flat or blown out. The first few days are tiny, with weak swell and periods of strong cross-shore winds that are just making a mess of things. It’s a real struggle to find anything rideable.

Now, we do get a spike in the swell on the 27th of August, with a solid 12 ft south-west swell rolling in. The energy is massive (1475), but here’s the kicker – the forecast says it's just too big for this reef break. It’s a high tide, wind-and-tide favorable situation, but the power is over-the-top. Unless you’re an absolute expert and know the ledge like the back of your hand, give that a miss. It’s not a beginner’s day. The afternoon only gets worse with cross-onshore winds.

We’ll see a few pulses of swell through the end of August and into September, but the wind is constantly messing with the quality. The first week of September is a write-off, with onshore winds and lumpy, choppy conditions. There’s a 5 ft swell on the 2nd, but it’s accompanied by a light cross-onshore breeze, so it’s not holding up.

The real standout, the one that’s got my heart pumping a little, is Saturday the 5th of September. We’ve got a moderate north-northeast offshore breeze, which at Kimmeridge Bay is the magic direction. That’s going to clean the place up. The swell is a modest 4 ft from the south-west with a period of 8 seconds, and the energy is moderate (150). It’s not going to be huge, but it’s the only window in this whole 16-day stretch where the wind is truly offshore and the waves are actually surfable. It’s going to be a bit ordinary, but it’s the best we’ve got. The water temperature is about average for the time of year, so no need for a thick wetsuit just yet, but you’ll want a decent spring suit.

The bad news is that this spot is very consistent, but that doesn't help when the conditions are poor. It’s a reef break, so it can handle a bit of swell, but it’s not a forgiving wave when it’s big. If you’re a beginner, steer clear of that 12 ft day on the 27th. For the rest of the run, it’s mostly a session for the patient. The crowds are often around here, but on that Saturday the 5th, with the offshore wind, you might get a bit of company.

So, to sum it up: the first week is a write-off. The second week has a few pulses, but the wind is against us. If you’re hanging for a surf, your best bet is Saturday the 5th of September. It’s the only real offer on the table. The rest of it? Kite-surfing weather, mostly.

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.
