The Lowdown

Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up at Kimmeridge Bay. I gotta be straight with you – it ain’t pretty. We’re looking at a long, bleak stretch before anything remotely surfable shows up, so don’t rush to wax your board just yet.

The water right now is a very unusual 69° – that’s much warmer than normal for the time of year.

Right now, Thursday the 27th of August, it’s a mess. We’ve got a tiny 2ft SSW swell with a short 4 second period. The wind is cross-on at 12 mph, leaving us with choppy, poor surf. The energy is weak (15). That’s the story for the next week and a half, honestly. The wind just won’t let up. Friday the 28th stays poor, with a 3ft WSW swell on Friday morning but a fresh 19 mph cross-shore wind making it lumpy. Friday afternoon gets a bit bigger, hitting 7ft from the WSW, but the wind cranks up to 28 mph cross-on – it’s just messy.

Saturday the 29th is a write-off. We see a 6ft SSW swell in the morning, but a strong 25 mph cross-on wind blows it out. By the afternoon, it gets worse: an 12ft SW swell with a near gale 34 mph cross-on wind. The wave energy jumps to 1689, but that doesn’t matter when it’s completely blown out. This is only for experts, and even then, not really.

From Sunday the 30th through to Saturday the 5th of September, the pattern is the same: small swells, mostly between 0.3ft and 6ft, with moderate to fresh cross-onshore winds, keeping the surface choppy and lumpy. There’s a brief moment on Wednesday morning the 2nd where we get a clean look with a light WNW cross-offshore breeze, but the swell is a pathetic 1.0ft with just 17 of energy. Not worth paddling out for.

Even Monday the 7th of September shows some promise at first glance. Monday morning we get an 8ft WSW swell with a 7 second period, and the wave energy is strong at 687. The wind is a light NW cross-offshore at 6 mph, so it’s clean. That’s the standout of the entire forecast, but only for the morning. That size is for experts only, and it’s at a reef break, so watch your head. But by Monday afternoon, the wind swings back to cross-on, the surf drops to 4ft, and it’s back to choppy conditions.

After that, the drop-off is brutal. From Tuesday the 8th through Friday the 11th, we’re back to tiny swells under 3ft, short periods, and cross-on or onshore winds. The only flicker of hope is Friday the 11th afternoon, where we see a clean 3ft SW swell with a moderate cross-offshore breeze, but still only 71 of energy – it’s a better look than most, but not good.

Overall, the only true standout is Monday morning, the 7th of September. Get it early, it’s clean and solid, but it’s for the experienced crew only. For the rest of us, it’s a waiting game.

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.
