The Lowdown

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

To be straight with you, this is a tough one. Over the next 16 days, there’s barely a sniff of anything worth paddling out for. The first real chance doesn't come until Friday, 11th September, and even then it’s slim pickings. Before that, we’ve got a long gap of small, choppy, or messy conditions with onshore winds ruining any chance of a decent wave.

The Period in Detail

Things start off poor. Thursday, 3rd September, has waist-high swell at 4ft from the WSW with a short, weak 6-second period and a cross-onshore breeze making it choppy. The combined energy is weak at just (120). It’s not worth getting wet.

Friday, 4th September, sees a bit more push with 7ft swell from the WSW in the morning, and the energy bumps up to moderate (393). The wind goes cross-offshore from the WNW, so it will be clean. But that size, over 5ft, starts pushing it out of beginner territory, and with a 7-second period it will be a bit lumpy and disorganised. It's not a standout.

Saturday 5th and Sunday 6th are tiny – 2ft or less – and not worth a mention.

The whole first week is a write-off, with onshore winds, short-period slop, or just flat, glassy conditions with no swell. Wave energy stays well below (100) for most of it.

The Only Glimmer

Now, on Friday, 11th September, there’s something. The morning session sees a 2ft swell from the west, but here’s the kicker – it’s got a 10-second period, which is decent, and a light NNW breeze giving cross-offshore, clean conditions. The combined energy is moderate at (106). This is a reef break (Kimmeridge Bay) and a longer period like that often means better-shaped waves here, with more push and longer waits between sets. But the size is tiny. It's surfable but very ordinary.

That afternoon, the wind swings offshore from the north at 18 mph, so it will be clean again, with 4ft swell from the WSW, but the period drops back to 5 seconds, making it weak and crumbly.

The Long View

After that 11th, it’s back to small, clean but tiny conditions. Wave heights drop below 2ft for days. The combined energy plummets into single or low double digits. Water temp feels about average for this time of year.

The Verdict

Honestly, if you’re desperate for a surf, Friday morning, 11th September, is the only window, and it’s for intermediates who want a clean, small wave on a reef. For anyone else, this 16-day window is a blank. The break is very consistent, so it tends not to stay this poor for long, but right now, it’s a quiet spell. For beginners or anyone wanting proper waves, there’s nothing here.

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.
