The Lowdown
Alright, folks, Rusty here. Let's see what Kimmeridge Bay has in store for us.
It's looking like a real rollercoaster, and mostly a frustrating one for those of us who want to paddle. We’ve got a whole lot of flat spells, and when the swell does show up, the wind is just tearing it apart. Kimmeridge Bay (Kimmeridge-Bay) is a reef, so it needs the right combo, and for most of this stretch, the combo is wrong. The water's about average for the time of year.
The first few days are dead. Sunday the 23rd and Monday the 24th are tiny swell with a stiff breeze—no go. Tuesday the 25th offers a glimmer: a 4 ft swell from the east with a short 6-second period. The morning is clean with a cross-offshore wind, but the energy is only moderate (127). It’ll be weak and wonky. Then it's back to onshore slop and tiny waves through the rest of the week.
From the 27th, bigger swell arrives but it's ugly. A 5 ft SW swell on Thursday afternoon with onshore wind is just choppy junk. Friday the 28th, the early morning is clean with offshore wind and a 2 ft SW swell (180 energy, 8-second period). That's a brief window for some shapely ones.
But the weekend turns into a beast. Saturday the 29th sees a 7 ft (305 energy) and Sunday the 30th an 8 ft (526 energy) SW swell, but with strong, messy cross-shore to cross-onshore winds. The energy is strong to very strong, but Kimmeridge will be a blown-out, lumpy mess. That's expert territory, and honestly, this setup looks more fun for a kiteboarder than a surfer. Stay off the water.
The first week of September is a slow fade. Monday the 1st is flat with light offshore winds. We get a last pulse on Thursday the 3rd with a 5 ft SW swell, but it's onshore and choppy. The second week is just lumpy windswell.
The Pick: There's no real standout. If you're itchin' for a wave, the early windows on Tuesday morning, August 25th for a tiny clean wave, or Friday morning, August 28th for a cleaner shot at some moderate energy, are your only real chances. Don't get your hopes up. This is a period to watch from the cliff tops.
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.
