The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Kimmeridge Bay over the next couple of weeks.
Honestly, it’s a pretty grim picture for the next 16 days. The bay is a reef setup that’s very consistent, but looking at the data, we’ve got a long stretch of nothing to get excited about. There’s a gap of about 9 days with no real surf to speak of right from the start.
The first hint of anything surfable doesn’t come until Tuesday, the 8th of September. Tuesday morning we’ll see a tiny 1ft swell from the WSW with a period of 11 seconds. The wind is a cross-offshore breeze, so it’ll be clean, but the wave energy is weak (68). It’s just about enough for a longboard if you’re desperate, but it’s not going to get the heart racing.
The only other period that might get you out of bed is Wednesday morning, the 9th of September. We’ve got a 2ft swell from the WSW, with a short period of 8 seconds. The wind is cross-off again, keeping the surface clean. The combined energy is still very weak though (62). It’s surfable, but it’s ordinary.
The rest of the outlook is a write-off. The wind is onshore or cross-shore for almost every session, and the swell heights rarely get above 2ft. The water temp is a notable 68°F, which is a massive 6°F warmer than usual for this time of year – feels like a warm bath, but the waves just aren’t there.
There’s a blip on the 16th of September, a Wednesday morning, with a tiny 0.7ft swell but a very long 12-second period, but it’s cross-offshore and clean. The energy is a paltry 20 though. It’s not going to break.
So, to sum it up: there’s nothing worth paddling out for. The only slim pickings are the Tuesday and Wednesday mornings of the first week, both for intermediates on small gear. Don’t bother with the rest; it’s a flat spell with a side of onshore chop. The bay is consistent, but when the swell is this low, it tends to stay poor for a while. Forecasts can change, but right now, I’d leave the board in the car.
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.
