The Lowdown
Alright crew, Rusty here. Let’s break down what’s happening at Kimmeridge Bay.
I’ve got to be honest, this is a lean 16-day outlook. There’s a big, dry gap at the start, and for the most part, you can leave your board in the car. The water temp is reading 68°, which is a whopping 6° warmer than usual for this time of year – very strange for September.
Let’s go through it. Friday the 4th kicks off with a 4ft swell from the WSW, but a 19 mph cross-wind is going to make it a total mess. Saturday and Sunday are tiny, barely a foot, and the wind is still messy. Monday the 7th afternoon brings a 5ft pulse with serious energy, but a strong 22 mph cross-onshore wind has it all choppy and lumpy. Tuesday the 8th morning is clean with a 3ft swell, but it’s nothing special.
The only real glimmer of hope comes right at the end. The standout, and really the only call, is Saturday morning the 19th of September. We’ll see a 4ft swell from the east with moderate energy, and more importantly, glassy conditions with barely a 3 mph breeze. It’ll be clean. The swell period is short, around 6 seconds, so it won’t have much power, but it’s your best shot. Expect that water to still feel weirdly warm.
Forget the rest of the second week. There’s a long-period, 14-second swell on the 15th, but it’s only 0.7ft – a ripple. The rest is flat or blown out.
So, the verdict: a long wait for a small, clean morning on the 19th. It’s not going to be a classic, but it’s the only window in sight. Stay patient.
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.
