The Lowdown
Alright, this is Rusty. Let’s take a proper look at what’s cookin’ for Kimmeridge Bay over the next 16 days.
Honestly, I gotta level with you – this stretch is looking flat as a pancake for the most part. We’ve got a long dry spell ahead. The first recommendation doesn’t even come up until Thursday the 17th, and even then, it’s nothing to write home about. There’s a real gap here with very little to get excited about. Let’s break it down.
The water’s sitting at a balmy 67° which is a solid 5° warmer than normal for this time of year – that’s very unusual. That’s about the only thing that’s pumping.
We start off with a whole lot of nothing until Thursday the 17th. On Thursday morning, we see the combined swell energy climb to a moderate (92), with some 1.3m swell coming from the WSW. Problem is, the wind is a fresh cross-onshore at 22 mph, making it lumpy and poor. The afternoon cleans up a bit with a cross-off breeze from the WNW at 19 mph, and the energy hits a moderate (111), but the wave height is still only 1.3m. It’s clean, but it’s small and not offering much power.
Friday the 18th morning shows a little more promise. The swell drops to 0.5m from the WSW, but the wind turns gentle and offshore from the NW at 9 mph, giving us clean conditions. The energy is weak (44), so you’re looking at small, clean little rollers. It’s a decent window for a longboard or a foamie if you’re desperate.
After that, it’s a long, slow slide back into tiny, weak surf. From the 19th right through to the 29th, we’re dealing with waves mostly under 0.3m, with combined swell energy in the single or low double digits. The wind is often light and variable, sometimes clean, sometimes with a bit of chop, but the lack of swell is the killer.
For a standout, if you can call it that, Friday the 18th morning is the best on offer. The cross-off wind and clean conditions make the most of the tiny 0.5m WSW swell. It’s not gonna blow you away, but it’s the only period where the conditions line up at all. For a more experienced surfer, Thursday the 17th afternoon has the most size at 1.3m and moderate energy (111), but it’s not a quality wave – just the biggest of a poor bunch.
Kimmeridge Bay is a reef setup that’s very consistent usually, but this forecast run is just barren. The periods are short (4-6 seconds), so there’s no real push or shape to anything. It’s one of those runs where you’d be better off checking the forecast again in a few days. It can’t stay this flat for long.

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.
