The Lowdown
Alright folks, Rusty here. Let’s see what’s cookin’ at Kimmeridge Bay.
Right off the bat, it's a rough start. We’re looking at a solid block of flat, poor conditions for the first week and a half. From Wednesday the 9th right through to the middle of the following week, it’s all tiny, chopped up, and onshore – nothing worth paddling out for. The wave energy is weak, barely getting into double digits (61), and often much lower, so don't even bother.
The water temperature is sitting at 68°, which is a whopping 6° warmer than usual for this time of year. That’s seriously unusual – you’ll be sweating in your wetsuit.
The first real glimmer of hope doesn’t arrive until Saturday the 19th. The morning shows a bit of a pulse with a 7ft swell from the SW, but the period is a short 6 seconds, and the energy is moderate (300). It’s still a messy, cross-shore wind, so the quality is marginal at best. Not a standout, just a sign that the ocean is waking up.
Sunday the 20th morning is the best of the bunch. We’ve got a 5ft WSW swell, a clean 6-second period, and light cross-offshore winds from the NW. The wave energy is moderate (247), and the conditions are clean. This is your window. It’s not epic, but it’s surfable and the wind is right. Kimmeridge Bay is a reef setup, so it will handle that swell direction better than a beach. Keep in mind this spot can get crowded, so be ready for company.
By Tuesday the 22nd morning, another small window opens with a 4ft swell and clean cross-offshore winds, but the energy is dropping again (80). It’s a weak, ordinary day.
After that, it fades back to nothing. The second week of the forecast is a total write-off – tiny, wind-affected, or completely flat. The long-range stuff on the 24th shows a 0.3ft swell with a very long 13-second period, but that’s just a whisper.
So, if you’re desperate, aim for Sunday the 20th morning. Otherwise, it’s a waiting game. The bay is a consistent spot, so this dead stretch is unusual, but it won’t last forever. Keep your eyes peeled.
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.
