The Lowdown

Right, listen up, it’s Rusty. I’ve been staring at the charts for Kimmeridge Bay, and I’ve got to be straight with you – it’s a grim stretch ahead. The whole 16-day window is looking like a write-off, so don’t be holding your breath for any decent waves. This is one of those blank runs that can happen around here, and right now, it’s a proper desert.

The first sniff of anything that isn’t a total mess doesn’t come until the afternoon of the 18th of September, and even then, it’s just a glimmer. We’re talking about a solid 14 days of nothing much before that. The water is unseasonably warm, about 20° with a massive anomaly of 3°, feeling much warmer than normal for this time of year, but that’s about the only bright spot.

Let’s walk through the gloom. Starting Friday the 4th, we’ve got a 7 ft swell from the WSW, but it’s a short-period 7-second windswell with a strong 16 mph WNW cross-off wind. The combined energy is moderate (373), but the conditions are just poor. The wind picks up more on the afternoon, turning it to mush. The whole first week is a write-off with tiny, weak swells and onshore or cross-shore winds. There’s a brief pulse on Monday the 7th with a long-period 15-second swell from the SW, but the 19 mph cross-on wind from the WSW just ruins it, making it lumpy and messy. The energy is strong (581), but it’s completely unsurfable for a paddle surfer. Honestly, if you’re kiting, it might look more interesting.

The second week is more of the same – flat or tiny, with weak energy. The only potential highlight is a tiny window on the 18th of September. The Friday morning brings a 4 ft SSE swell with a 5-second period, but the wind is a clean 9 mph offshore from the NE, keeping it clean. The rating is a 1/10, which is the best we get, described as “surfable waves but very ordinary conditions”. It’s not going to be a standout, but it’s the only thing that even gets a score. The swell direction is from the WSW, which is a long way off the optimum SW for Kimmeridge Bay, so the waves will be pretty weak and won’t wrap in well. The crowds are often a problem, and with the break being very consistent, it’s a spot that usually works, but this forecast is just a dud.

So, to sum it up: there’s no true standout in this forecast. The 18th of September is the only day that might be worth a look for a very desperate surf, but it’s a long shot. Don’t plan your week around it. The forecast can change, but for now, it’s a total blank.

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.

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.
