The Lowdown
Alright folks, Rusty here, looking at the Kimmeridge Bay forecast for the next couple of weeks. First things first, the water temp is sitting at 68°F with a massive 6°F anomaly, so it’s much warmer than usual for this time of year - a nice surprise if you’re getting in.
But let’s be real, the start of this outlook is a tough one. We’re looking at a solid 8-day stretch of nothing worth paddling out for. The whole first week through to the morning of Wednesday the 11th is just messy - cross-onshore winds, lumpy chop, and the wave comment for every single session is "poor surf conditions". Even when the swell bumps up to 7ft on Friday the 4th, the wind is a fresh cross-shore, making it junk. Not a single session scores above a 1 out of 10 during that period. It’s a dead run.
The first real glimmer of hope comes on the morning of Friday the 11th. We’ve got a clean 6ft swell out of the WSW, with a light offshore breeze from the NNW, and the combined energy is a solid 269 (moderate). The wave comment says "expect good surf conditions". That’s the standout. The swell direction is SW which matches the optimum, and with that offshore wind, Kimmeridge Bay should be clean and lined up. It’s an intermediate reef break and it’s "very consistent", so it’ll be working. The afternoon sees the wind swing cross-shore, so the morning is the window.
Saturday the 12th morning is worth a mention too. It’s glassy - a rare treat - with a 4ft swell (WSW) and 104 energy. The comment says "surfable waves but very ordinary conditions", so it’s not a standout, but you could get a few clean ones if you’re desperate.
After that, things get messy again. A bit of a onshore blow on Sunday the 13th with 6ft swell, and then it’s back to cross-shore junk. The very end of the window on Wednesday the 16th afternoon shows a big 10ft SW swell with 952 energy (strong), but it’s crossed-off and the comment is "poor surf conditions", so that’s likely a washing machine for experts only. Thursday the 17th morning has a clean 5ft SW swell with 529 energy and a cross-off wind, but again, the comment is "poor". It’s a frustrating forecast.
The only real standout is the Friday the 11th morning session. That’s your best bet. After that, it’s a gamble.
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.
