The Lowdown
Alright, grab a coffee, or whatever it is you’re drinking. Let’s talk about Kimmeridge Bay. This is the only spot on the menu for the next couple of weeks, and to be honest, it’s a bit of a tough watch for most of it.
The water temperature is sitting at 69°F, which is a whopping 7°F warmer than usual for the time of year – that’s really unusual, almost like swimming in a bath. But you’ll need a thick suit, and possibly a kite, for most of this stretch because the wind is just not playing ball for proper surfing.
We don’t get a sniff of a decent wave until we’re well into the forecast. For the first week, from Monday the 24th of August right through to Saturday the 6th of September, it’s a write-off. We’re talking flat spells, messy onshore slop, and cross-chop that would make anyone seasick. There’s hardly any swell energy, with readings mostly in the low double digits, like 3, 6, or 22, and the wind is constantly ruining any chance of a clean line. That’s a solid 10-day stretch of nothing good.
Finally, we get a glimmer of hope in the second week. Monday the 7th of September is your only real standout. Early morning, we’ve got solid 10ft swell from the SW, with a period of 8 seconds, and a clean, fresh offshore wind from the North. The energy meter is cranking at 1099 – that’s strong, powerful stuff. The break is very consistent, so there’ll be waves, but at 10ft this is strictly for the experts only. Beginners, stay on the beach. If you’re good, paddling out will be manageable with those clean conditions and the long gaps between sets. It’s a reef break, so the long-period energy will wrap in nicely along the ledge.
The afternoon of that same Monday gets even bigger, with 12ft swell from the WSW, but the forecast says it might be *too big* for Kimmeridge Bay, which maxes out the scoring. That is the only day worth circling on your calendar, and early morning is the call. After that, the energy drops, and the wind gets messy again, with a massive 15-second period groundswell but ruined by a cross-onshore breeze on the Tuesday afternoon.
So, overall, you’ve got one real shot: Monday the 7th of September morning. The rest is a long, dusty wait. Don’t get your hopes up too high for the second week; it’s promising but unreliable this far out.

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.
