The Lowdown

Right then, let’s take a look at what’s on offer for Kimmeridge Bay. It’s a forecast that will test your patience, because the truth is, for the next several days there’s just nothing doing. We’re looking at a real flat spell to kick things off, with small, messy, cross-onshore junk and combined swell energy barely scratching double figures. Waves are around the 2 ft on Saturday the 12th but it’s a tired, short-period windswell at 8 seconds, and a fresh 16 mph cross-onshore wind just chops everything to pieces. This pattern of poor surf carries right through, with energy readings that are weak (89) and dropping away.

Sunday the 13th and Monday the 14th are more of the same – the swell sticks around 0.7 ft to 4 ft, but wind stays cross or cross-onshore, and the period is a dismal 5 seconds. There’s just no power and no shape. The water temperature here is about average for the time of year, so no shock there.

Tuesday the 15th afternoon offers the first tiny glimpse of something cleaner. A cross-offshore wind from the northwest at 12 mph tidies things up, but with the swell at only 3 ft and a period of 4 seconds, the combined energy is just 21. It’s clean, sure, but there’s hardly a wave to ride.

We get another clean window on Wednesday the 16th morning, with a cross-offshore northwest wind at 16 mph and a 2 ft swell (8 second period, weak energy of 45), but again, we’re in that knee-to-waist high territory with no punch. The afternoon holds similar, small and clean.

A spike in the wind shows up Thursday the 17th, with a fresh 19 mph cross-onshore in the morning making a mess of things, but then the afternoon cleans up nicely with a WNW cross-offshore at 19 mph. Swell bumps up a little to 4 ft but the period is a short 5 seconds, and energy only reads 72 – still poor surf quality.

From Friday the 18th onwards, it’s a long, drawn-out run of tiny waves, mostly 0.3 ft to 1.0 ft. The combined energy falls to single or very low double digits – a few odd pulses of longer period swell appear (12 to 14 seconds) but they’re accompanied by onshore winds, resulting in no worthwhile surf. The glassy morning on Wednesday the 23rd September is a real tease; flat as a tack, zero energy, no swell at all.

There’s a brief flurry on Monday the 21st afternoon when we see a 3 ft swell from the east, a light cross-offshore breeze, and clean conditions. The energy is still low (36) and the period is short (5 seconds), so it’s not a standout, just the least bad option in a grim run.

Kimmeridge Bay (Dorset) is very consistent here, and this is simply a run of dire conditions. Honestly, for a surfer, there’s no one or two true standouts in this entire 16-day window. The blank run starts now and lasts for the whole outlook – every session is rated poor. Even when the wind gets clean, the swell is too small, the period is too short, and the energy is dead. It’s looking more interesting for a paddleboard than a surfboard. Hang tight, the forecasts can change, but for now, keep the board in the van.

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.
