The Lowdown

G'day, I'm Rusty. Let's have a look at what's on offer for Kimmeridge Bay over the next couple of weeks. I'm not gonna sugarcoat it – this stretch of coast is in for a pretty quiet spell. The reef here needs a good push from the SW to work its magic, and while we've got a bit of swell direction lining up, the size and the wind just aren't cooperating most days. The water is running at 68°F, which is a massive 6°F warmer than normal for this time of year – that's very unusual, almost feels like a late summer holdout.

For the first week, honestly, it's grim. From Wednesday the 9th right through to Monday the 14th, we're looking at tiny, weak swells and mostly cross or onshore breezes. Wave energy is barely registering, with figures like 80 (weak) on Wednesday morning, dropping to single or low double-digits through the weekend. We do get a bit of a pulse on Friday the 11th morning – a 3 ft WSW swell at 6 seconds, and clean cross-offshore wind from the WNW at 15 km/h. It's surfable but ordinary, scoring just a 1. The waves are small and the period is short, so it's not going to be a standout. Mostly, you'll be fighting cross-onshore chop with winds up to 19 mph, especially Saturday and Sunday.

The only real glimmer of hope, and I mean the only one, is on Wednesday the 16th of September. After a solid run of nothing, the swell jumps up to 7 ft in the morning and 7 ft in the afternoon from the WSW, with a period of 7 seconds. The combined energy jumps to 385 in the morning and 421 in the afternoon – that's moderate to strong energy. Both sessions have clean conditions with cross-offshore wind (NE 12 mph in the morning, light WNW 6 mph in the afternoon). The afternoon looks the pick of the whole forecast: light breeze, clean, with a "expect good surf conditions" rating. That 7 ft wave is a bit meaty though – over 8 ft it's expert territory, but this is right on the edge, so intermediate surfers should be okay if they're experienced. The 7-second period is short-period windswell, so it won't have the grunt of a groundswell, but it'll be fun.

After that pulse, it drops away again fast. Thursday the 17th has a clean 4 ft morning but it's weak and dropping, and by the weekend of the 21st we're back to tiny 0.7 ft to 1 ft slop. The last week is a write-off with barely a ripple. So, if you want a wave, pencil in Wednesday the 16th. The afternoon session at Kimmeridge Bay is your best bet – just be aware the crowds here are "often", so you won't be alone. The rest of the time, leave the board at home or take the kite out, because that's about all the wind is good for.

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.
