The Lowdown
Alright, surfers, Rusty here. Let’s see what’s on offer for the next couple of weeks.
To be honest, the first part of the outlook is a tough one. Right up until the 17th of August, it’s a flat spell. There’s nothing doing. The swell is tiny, the wind is messy, and it’s just not worth getting the board wet.
The one bright spot in this whole 16-day window is Kimmeridge Bay. The water is a very warm 68°F, which is nearly 7° warmer than usual for this time of year, so it’s a real treat.
Circle Monday the 17th of August on your calendar. The morning is our best chance. We’ve got a solid 10ft swell from the WSW, with a period of 8 seconds. The energy is moderate (894). The wind is from the WNW at 15 mph, giving us a clean cross-offshore breeze. That’s a perfect setup for this reef break. It’s very consistent and normally handles a SW swell well, so it’s a great match. This is a big wave for the intermediates; 10ft is expert territory, so beginners should stay on the sand. Crowds are ‘often’, so you’ll have company.
The afternoon of the 17th is still ok, with 7ft of swell and the same clean wind, but it’s not as punchy (363).
After that, the swell drops off quickly into small, choppy junk on the 18th and 19th. The 20th of August offers a tiny 2ft wave with clean conditions, but it’s barely worth a mention.
Bottom line: the only real session in this forecast is the morning of Monday the 17th of August at Kimmeridge Bay. The rest of the time, it’s a waiting game.
Stay frothy.
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.
