The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at Kimmeridge Bay, and honestly, the next 16 days are a bit of a tough watch. The forecast is showing a whole lot of weak, messy conditions, and the swell energy is barely getting a pulse. For the first week, the surf is a real struggle. The first few days are a write-off, and the pattern doesn’t really improve much. The best we can hope for is a minor window, but it’s not going to be anything to write home about.

The first real chance for a paddle comes on Thursday, August 13th, in the morning. We’ve got a 2ft swell nudging in from the WSW with a period of 9 seconds. The combined energy is moderate at 101. The wind is a gentle cross-offshore breeze, which will keep the surface clean. It’s surfable, but very ordinary. The swell is small, so it’s one for a longboard or a funboard. The water temp is about average for the time of year, nothing unusual.

From there, the forecast is a long, dry spell. There are days and days of nothing but tiny, weak waves with poor wind. We’re talking about a gap of almost a week with no real recommendations. The swell energy dips into the single digits, and the wind is either onshore or cross-shore and lumpy.

There’s a notable spike in energy on the morning of Thursday, August 20th, with a 4ft swell from the west, but the period is short at 5 seconds. The energy is moderate at 115, but the wind is a strong cross-offshore breeze, so it’ll be clean. However, the wave quality is still rated as poor, and it’s that short-period windswell that’s just not going to give you any real shape. It’s a frustrating one.

The end of the 16-day window shows a bit of a jump in size. On the morning of Thursday, August 27th, we see a 7ft swell from the WSW, with a period of 7 seconds. The combined energy jumps to 384, which is moderate to strong. But the wind is a moderate cross-shore, creating a chop. At 7ft with short period and cross-shore wind, this is one for the experts only, and even then, the quality will be poor. It’s more of a messy, powerful windswell. For the average surfer, the setup looks more interesting for kite surfing than paddle surfing.

So, overall, it’s a grim outlook. If you’re desperate for a splash, the very early morning of August 13th is your best bet, but don’t expect much. The rest of the window is a waiting game.
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.
