The Lowdown
Right then, Rusty here again, same region, same story in feet and knots. Kimmeridge Bay is flat out no good for the next 16 days. Every single entry in the data says "poor surf conditions" with a score of zero, so there’s no standout session, no sneaky pulse, nothing worth chasing.
We’re looking from Friday the 14th of August all the way to Saturday the 29th of August, and it’s a total blank. Friday morning starts with a tiny 0.7ft swell from the WSW, period at 9 seconds, and a cross-off NW breeze at 9 knots. The combined swell energy is only 15—barely a ripple. The afternoon bumps to 2ft but the wind swings west and goes cross-shore, killing any chance of a decent wave. There’s a gap of over two weeks with no recommendation, just flat, messy, or blown-out conditions.
Saturday the 15th has clean offshore wind from the north at 16 knots in the morning, but the swell is only 0.7ft with an 8-second period. Combined energy is 8. It’s pretty but you can’t surf it. Sunday the 16th is similar—0.7ft, offshore NNE breeze, energy at 6. Monday the 17th gives you a moment of total glass: no wind, a 0.3ft swell, energy of 2. It’s a lake. By Tuesday the 18th, the swell reaches 2ft in the morning and 3ft in the afternoon, but it’s a short-period 4-5 second windswell with a fresh cross-onshore breeze at 19 knots, making it lumpy and ugly.
Every day follows the same pattern: either too small, onshore wind, or both. Even on Thursday the 27th of August when the swell hits 4ft and combined energy finally cracks triple digits at 101, the wind is a fresh cross-shore from the east at 19 knots with a lumpy cross-chop. Period is only 6 seconds, so there’s no power and no shape. That setup looks more interesting for kite surfing than paddle surfing.
Water temp is about average for the time of year, nothing unusual.
I don’t like delivering bad news, but Kimmeridge Bay is a reef that needs a solid south-west swell and clean wind. This 16-day run has neither. The reef is exposed, but without swell, it’s just a pretty spot. For a break that’s "very consistent," this is a rough spell. Forecasts can change, but right now, leave the board at home.
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.
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.
