The Lowdown
Alright folks, Rusty here. Let's be straight with you. I've scanned the charts for the next couple of weeks, and it’s a bit of a tough stretch for us at Kimmeridge Bay. We're looking at a long, quiet period before anything even starts to look interesting.
Kimmeridge Bay is a reef setup that's very consistent, but for the next week and a half, we're just not seeing any swell of note. The water is a balmy 68°, which is a massive 6° warmer than usual for this time of year – that’s a real talking point, water feels like a bath compared to normal.
To be honest, from now until around the 22nd, it's a write-off. We're talking a solid ten-day gap with no real surf on offer. The odd pulse shows up, like a 3ft swell on the 11th, but it’s coming from the ESE with a short, weak 5-second period and being blown out by a 15 mph cross-shore wind. It's just mess. The energy levels are in the single digits and low double digits – weak, lifeless stuff. Even when the wind goes offshore, like Friday morning the 14th with a light WNW breeze, the swell is only 1ft. You'd be fighting for knee-high slop.
The pattern continues through the 15th, 16th, and 17th. There are some clean windows with offshore winds, but the swell heights are tiny, around 0.7ft to 3ft. The periods are short, in that 3 to 8 second range, which means it's just wind chop without any push. By the 18th, we get a proper 19 mph cross-shore breeze and the sea state is a mess. The 19th and 20th are better for wind but again, no swell to speak of. It’s a long, boring stretch of flatness, I won't lie to you.
Finally, we get a glimmer of hope on Sunday the 23rd. The northerly offshore wind arrives, with the swell picking up to 6ft in the morning and 5ft in the afternoon. The period jumps a bit to 6 seconds, and the energy finally gets into the hundreds, hitting 200 and 164. It's still a short-period swell, so it won't be perfect, but it will be clean with that offshore wind. This is the only surfable window we have, and it's the standout of the whole 16-day period. It's a decent size for the bay, not for beginners, but for the intermediates out there, it could be a fun Sunday session. The swell is from the WSW, which is close to what the bay really wants, so it should wrap in with some shape.
Beyond that, the 24th and 25th drop right back down to 0.3ft. There is a long-period swell popping up on the 24th (20 seconds) and 25th (16 seconds), but it's tiny and the wind gets messy, so it's nothing to get excited about.
So, there you have it. One day on the 23rd looks like it could have some fun, clean waves. It's a long way out, so keep your fingers crossed it holds. Before that, it's a flat spell like we haven't seen in a while. The bay is too consistent to stay poor for long, so keep checking back, but don't hold your breath for the next two weeks. This is Rusty, signing off.

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.
Kimmeridge Bay is 18 km (11 miles) from the city of Poole. If you plan a holiday in South Coast of England, look for hotels and other accommodation in Poole. Poole has rooms for a wide range of budgets as well as car hire and transport links.
