The Lowdown
G'day, Rusty here. Well, I've had a good long look at the charts for our neck of the woods, and I gotta be straight with you – it's a real lean stretch. The entire 16-day window from the 14th of August right through to the 29th is a write-off for any decent waves. Every single forecast slot shows "poor surf conditions," so there's nothing to get excited about.
The only break we've got to look at is Swanage, and it's a frustrating spot to call home right now. It's a very sheltered one, exposed to the SW, which is tough because most of the swell we're seeing is tiny and mixed up. It rarely breaks as it is, so this kind of flat spell isn't a huge surprise, but it still stings.
We start Friday the 14th and Saturday the 15th with clean, offshore winds but barely a ripple. Swells are tiny, between 0.7 ft and 2 ft, with ocean energy readings in the low double digits (15 and 18 on the energy scale) during the best windows – that's barely a pulse. The water temp is about average for the time of year, so no surprises there. We get a bit of a long-period groundswell signal on the 19th of August, a 13-second period from the NW, but with a height of just 0.3 ft and no real energy behind it (5 on the energy scale), it's a phantom.
The only day that even remotely looks like a paddle is Sunday the 23rd of August. By the afternoon, we get the biggest swell of the whole outlook at 3 ft from the ENE, with moderate energy (52 on the energy scale), and a clean, light cross-offshore breeze. But 3 ft with that short of a period (5 seconds) from the east is going to be weak, crumbly, and disappointing. It’s just not worth the drive. Everything else is either flat, blown out, or onshore.
Honestly, it's a blank run. Forecasts can change, but for now, the only thing breaking is the hearts of the local crew.
Rusty.

Information about the Swanage Surf forecast
The above surf forecast table for Swanage provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Swanage can be found by selecting the local surf guide option on the grey menu. Our Swanage 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 (Swanage) 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 Swanage 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.
Swanage is 13 km (8 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.
