The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one for Swanage. Looking at the whole 16-day window, I’ve got to be honest, there’s not a single standout day that’s gonna get the heart pumping. We’ve got a long stretch of flat to tiny, messy conditions, and the few moments where there’s a bit of size come with strong winds that make it a challenge.
The first real pulse of activity shows up around Tuesday the 25th of August. We’ve got some swell pushing in from the East, about 5ft, but with a short period of just 6 seconds and onshore winds, it’s going to be a lumpy, choppy mess. The combined energy is moderate at 136, but it’s not going to be a fun paddle. The water temperature is running about 69°, which is much warmer than normal for this time of year, so at least you won’t be freezing while you’re getting knocked around.
The window picks up a bit on Friday the 28th of August. The morning sees a 4ft SW swell (9 seconds) with a cross-offshore breeze, giving us some clean conditions and a combined energy of 284. It’s the best of a bad bunch, but still not a ripper. The real size comes on Saturday the 29th of August, with a 7ft WSW swell in the afternoon. The wind is strong offshore from the West, cleaning it up, but with a period of just 7 seconds and that size, it’s a powerful, bumpy, and thumping wall of water. The combined energy is a strong 450. This is only for expert paddlers who can handle the paddle out and the power. It’s more of a battle than a session.
After that, it drops off again. The 31st of August has a 4ft swell with strong offshore winds, but again, a short period of 6 seconds makes it hard work. From the 1st of September onward, we’re back to tiny, insignificant waves. A few clean days with offshore winds, but the swell is barely a ripple, often under 2ft.
So, the honest truth: there are no true standouts on offer here. If you’re desperate for a paddle in the second week, the 29th of August is the only day with any real push, but it’s a rough, expert-only affair. For the rest of us, it’s a blank run. In Swanage, it tends not to stay poor for long, but this window is a write-off for a good surf. I wouldn’t be charging down to the water just yet.
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.
