The Lowdown
Alright, let’s get into it. The next 16 days at Kimmeridge Bay are a bit of a waiting game, to be honest. There’s a big gap at the start with no real surf to speak of. The first proper blip on the radar doesn’t show up until Tuesday the 8th of September, and even then it’s nothing to write home about for a while.
Kimmeridge Bay is a reef setup, fairly exposed to the southwest, and it’s very consistent when it gets swell, but the problem here is the swell just isn’t cooperating. The water temperature is sitting at 69°F which is much warmer than normal for this time of year – a good 7°F above average, so you’ll be in for a warm one if you go in.
The main action, if you can call it that, kicks off on Tuesday morning the 8th of September. We’ve got a little 3ft groundswell from the WSW with a period of 10 seconds, coming in with a light offshore breeze from the north and clean conditions. The combined wave energy is moderate for this little window, at 107. It’s surfable, but very ordinary. The afternoon picks up a bit with the same size swell, but cleaner again with a WNW cross-off breeze. The period’s still 10 seconds, so it’s got a bit of shape, but it’s tiny. No standout sessions here, just a chance to get wet.
Other than that, the whole 16-day window is a dud. You’ve got a few mornings with clean conditions and tiny 1ft to 3ft waves, but nothing that’s going to get your heart racing. The wind is usually onshore or cross-shore, and the swell is mostly short-period junk. The whole thing looks pretty flat and frustrating. The spot is consistent, but there’s just nothing to be consistent with.
Stick to the long-range forecast, but don’t hold your breath. The only real standout is that Tuesday the 8th of September morning, and even that’s a stretch.

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.
