The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Kimmeridge Bay.

First off, I gotta be straight with you – it’s a tough stretch ahead. The water is sitting at a very unusual 69°, which is a whopping 7° warmer than normal for this time of year. Feels more like the Med, but the surf? It’s just not happening for a long time. The whole first week and a half is a write-off. From Tuesday the 18th of August all the way through to the end of the month, the forecast is a flat, messy, or just plain ugly story. The wind is mostly cross or onshore, and the swell is tiny. We’re talking knee-high dribble with periods of 4 to 6 seconds – that’s just wind slop. The combined energy is mostly well under 100 (weak), with only a few brief spikes of moderate energy (106, 133) on the 18th and 20th, but those are ruined by fresh to strong cross-shore winds and lumpy chop. Kite surfers might get a kick out of that onshore breeze, but for a paddle surfer, it’s a no-go. There’s a clean moment on the 21st and 22nd but with swell heights of just 1ft to 2ft (SW), there’s nothing to ride. This blank run of no recommendations lasts for a solid 12 days.

Now, just when you’re about to give up hope, the calendar flips to September. The first of September is the only real standout in this whole outlook. It’s a long way off, so treat it as promising but not locked in. Tuesday morning the 1st of September, we finally see a solid pulse of south-west groundswell hitting 7ft, pushing up to 8ft in the afternoon. The period is 7 to 8 seconds, which is okay, but the real kicker is the wind. It’s a fresh north-west breeze, holding clean and cross-offshore. That’s clean conditions for a reef break like this. The combined energy jumps to 449 in the morning and 582 in the afternoon – that’s strong wave energy. Now, this is a reef, so it’ll handle the size. But heads up: at over 7ft, this is expert territory. Not one for the beginners. The swell is straight out of the optimum SW direction for this spot, so it should be lining up well. The 2nd of September still has some 5ft leftovers, but the wind swings westerly cross-shore, and the energy drops back to 114 (moderate), so it’s not the same quality.

That’s the story. A long, flat, messy wait, then a single, solid window on the 1st of September for the experienced crew. Keep your eyes on the charts for that one.

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.
