The Lowdown

Alright, Rusty here, and I gotta be straight with you – this is a tough one to write. Looking at the whole 16-day window for Kimmeridge Bay, it is a proper struggle. We’ve got a long, dry run of poor surf conditions ahead. The first real recommendation doesn't actually show up until the very end of the run, so we’re looking at a big gap of next to nothing for most of the period.

Let’s start with what’s on offer. The first surfable day is Monday, the 14th of September. That’s a long way out, so take this with a pinch of salt, but it’s the only window that has any kind of pulse. The swell will be coming from the E at 5ft with a short period of 6 seconds. That’s not a lot of grunt, and the energy is only moderate (155). The wind will be a cross-shore, so it’s likely to be a bit messy and choppy.

Honestly, it’s grim. The whole first week and a half is a write-off. We’ve got cross-onshore winds, really short-period windswell, and wave heights that barely get above the knee. The water is still much warmer than usual for this time of year, about 69°, but you won’t care about that when you’re staring at a flat, lumpy ocean.

The only standout, and I use that word lightly, is that last day on the 14th. It’s not good, but it’s the best of a bad bunch. The break is a reef, so it might handle the swell direction a little better than a beach break, but with that short period and cross-shore wind, it’s going to be a frustrating session. The swell is 5ft, which is manageable for intermediates, but the quality just isn’t there.

This is a blank run. It’s one of those times where the forecast is what it is, and you’re better off waiting for the next system. Forecasts can change, but right now, it’s a long wait.

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.
