The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Kimmeridge Bay.
Overall, it’s a pretty grim run for the next two weeks. We’ve got a long stretch of flat-to-manky conditions with barely a ripple to get excited about until the very end of the month. The first recommendation doesn’t pop up until Thursday the 30th of July, so that’s over a week of waiting. The water is a weird one – for the first report on Friday the 17th, it’s sitting at 66°F, which is a massive 5°F warmer than normal for this time of year. Very unusual for the UK.
From Friday the 17th right through to Wednesday the 29th, it’s a wasteland. We’re talking tiny swell heights – mostly 0.3ft to 2ft – with weak energy readings (single digits or low teens in brackets). The wind is all over the shop, mostly cross-on or cross-off, and the periods are short, under 8 seconds. It’s just not worth paddling out. There are a few glassy moments here and there, like Friday morning the 17th with a 3 mph WNW breeze, but with only 0.3ft of swell and energy of 3, it’s flat calm. You’d be floating, not surfing.
The only real standout is Thursday the 30th of July. That’s your window. Thursday morning brings a clean 8ft swell from the WSW with a period of 7 seconds and energy of 649. That’s a solid, moderate wave energy. The wind is light and cross-off from the east at 6 mph, so the surf will be clean. This is proper-sized stuff – over 8ft, so it’s for experienced surfers only. The reef at Kimmeridge Bay will handle that long-period groundswell well. Thursday afternoon gets even better with glassy conditions, 8ft from the same direction, and energy of 497. If you’re an expert, that’s the day.
Friday the 31st drops back to 4ft with clean cross-off wind, but the energy is only 128. It’s a fade-out. The rest of the first week of August is back to small, choppy junk.
So, don’t hold your breath for the first week and a half. The one and only true standout is Thursday the 30th of July – get on it if you’re skilled, but expect crowds because this spot can get busy. It’s not often we get a window like that.
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.
