The Lowdown

Alright, listen up. It’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for getting wet at Kimmeridge Bay. We’ve got a solid stretch of small, weak, and mostly messy surf, and honestly, you might be better off doing anything else for a while. There’s a long gap with nothing worth paddling out for, so don’t hold your breath.

We start off this Wednesday, the 9th, with some tiny 2.6ft waves from the WSW. The period is a weak 8 seconds, and the swell energy is a meager 80. It’s clean-ish with a cross-off breeze, but there’s just no power. By the afternoon, it’s even smaller at 2ft. The next few days, Thursday and Friday, are more of the same – dribbly 1.3ft to 3.3ft waves, with a bit of chop from cross and cross-on winds. The energy is in the doldrums, all under 100. Saturday the 12th sees a small bump in size, pushing to 5.2ft by the afternoon, but it comes with a fresh 30 km/h cross-on wind and a lumpy mess. The energy jumps to 164, but the quality is junk. Sunday the 13th backs off again to under 3ft. Water temp here is about average for the time of year, nothing crazy.

The start of next week is a total write-off. We’re talking ankle-biters at 1.3ft or less, with periods that are all over the place. A slight 9-second swell on Monday is just enough to mess with the surface but not enough to surf. The energy readings are in the low teens and single digits. This flat spell looks like it will stretch for a few days, from the 14th through at least the morning of the 15th.

There’s a bit of a spike on the 16th, with a 5.6ft WSW swell on Wednesday afternoon, but the period is a crumbly 6 seconds and it’s cross-on. The energy gets to 188, which is moderate, but it’s not going to be any good. The wind and the short period will kill it. We see another pulse of 3.6-3.9ft around the 17th, but again, it’s short-period and onshore.

The last week of the forecast, from the 18th onward, is a real test of faith. There's a lot of tiny, clean surf that will be tempting, but it’s minuscule. Friday the 18th has some cross-off and offshore wind, and by the 20th we see a new swell direction from the ESE, but the heights are pathetic, 2.3-3ft at best. The energy is weak.

Look, the only thing that even sparks a glimmer of hope is the long-period swell showing up on the charts for the 23rd of September. We’re talking a 15-second groundswell, but it’s only 0.3ft. It’s a whisper, not a wave. That long period at a reef like this could be magic, but with no size, it’s just a ripple. That is a promising sign, but it’s way off and a longshot. For now, this is a blank run, which is more normal for this stretch. It tends not to stay this poor for long, so keep your eye on the charts, but don’t get your hopes up this week.

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.
