The Lowdown

Right then, I’ll be straight with you – it’s a tough run coming up at Kimmeridge Bay. This is a classic reef set-up that needs the stars to align, and for the next two weeks, they’re mostly out of sync. There’s no surf on offer that I’d recommend paddling out for. The first few days are a write-off, and then we’re looking at a long, frustrating stretch of blown-out, messy, or tiny conditions.

Starting now, Friday the 28th, it’s poor. Morning has some lumpy cross-shore chop on a tiny 3 ft swell with a short 4 second period – completely gutless. That afternoon the wind cranks up to a strong 31 mph cross-onshore, pushing a 7 ft swell into a messy, near-gale mess. Saturday the 29th is no better; heavy rain showers and a near gale force cross-onshore wind will have the bay totally shredded. The swell gets to 12 ft, but with that wind, it’s unrideable. This blows through Sunday and Monday, where the wind finally eases, but the swell is still crossed-up and choppy. Monday morning the 31st gives us a clean look with a cross-offshore breeze, and a 6 ft swell from the WSW, but the combined energy is still modest at 299, meaning it's inconsistent. Still, it's the cleanest we get, so if you’re desperate, that’s your window.

After that, it falls away again. We go into a flat spell. Tuesday the 1st to Thursday the 3rd of September is tiny, with poor wind. Friday the 4th and Saturday the 5th are messy and weak. The whole first week is a bust, basically.

There’s a glimmer around Sunday the 6th of September. After a morning of fresh cross-onshore wind, the afternoon goes glassy and clean with an offshore breeze from the north. The swell is a pathetic 2 ft, but with clean conditions. That’s not for a surfboard, though.

Monday the 7th and Tuesday the 8th have similar tiny, clean mornings but no real energy. Then from Wednesday the 9th, we get a new pulse of swell, but the wind is onshore and strong again. A 7 ft swell shows up on Wednesday afternoon with a moderate breeze and a lumpy cross-chop. The energy ramps up to 326, but the quality is poor.

The worst of the wind returns on Thursday the 10th with near gale cross-onshore winds and a 6 ft swell. Friday the 11th and Saturday the 12th finally see a clean up with strong cross-offshore winds, but the swell has collapsed to 1 ft and 0.7 ft respectively. A long 8 second period suggests some distant energy, but there’s nothing to push it. It’s a clean empty line-up.

Overall, this is a frustrating forecast. The water temp anomaly is about average for the time of year, so that’s not the problem. The problem is the wind and the inconsistent swell windows. Nothing here is worth the drive. It’s a blank fortnight for the most part.

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.
