The Lowdown
Right then, let’s have a look at what’s on offer for Kimmeridge Bay over the next couple of weeks.
Alright, I’m gonna be straight with you – this is a tough outlook. The whole 16-day window is pretty much a write-off for decent surf. We’ve got a long stretch of poor conditions, with the first few days looking particularly grim. The combined swell energy is very weak, barely cracking 44 (44) on Tuesday morning, and it just doesn't get going. The water temperature is a very unusual 68°, which is a massive 6° warmer than normal for this time of year, so you’d be warm in a spring suit, but that’s about the only nice thing I can say.
Tuesday the 1st kicks off with a weak 2ft of swell from the WSW and a cross-shore wind that’s already messing things up. The period is a short 8 seconds, so it’s all wind-slop. It stays like that for days – small, weak, and choppy. Wednesday the 2nd sees a bit more size, up to 5ft, but winds are getting stronger from the SW, making it lumpy and awful. The energy picks up a touch into the 100s (116) but it’s still poor quality.
Thursday the 3rd brings the biggest surf of the whole period, with 5ft from the WSW and the combined energy jumping to 166 (166), but it’s completely blown out by a fresh, cross-onshore breeze. For a reef break, that’s a waste of energy. Friday the 4th is clean in the afternoon with a cross-offshore wind, but the swell is only 5ft and the period is a short 6 seconds, so it’s not going to have any shape.
Saturday the 5th morning is glassy and clear, but the swell drops to a pathetic 1ft. It’s a total flat spell. This poor run of weak, small, or onshore junk continues day after day. There’s a brief moment on Tuesday the 8th where the swell gets up to 8ft from the WSW with a period of 7 seconds and a combined energy of 729 (729), but the wind is a fresh cross-shore, making it lumpy and messy. At that size, it’s only for experts anyway, and it looks like a washing machine.
The rest of the second week is a mix of clean but tiny waves, or small, choppy junk. The periods are mostly short, under 8 seconds, and the energy is frequently in the single or low double digits. There’s a clean, glassy morning on Wednesday the 16th with a tiny 2ft swell, but it’s not surfable. Honestly, there isn’t a single standout in this entire forecast. The crowd profile doesn’t even matter because the conditions are so poor. If you’re into kitesurfing, the stronger, messy winds on the 3rd, 4th, and 8th might look interesting, but for paddle surfing, save your energy.

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.
