The Lowdown
Alright folks, Rusty here. Let’s be straight with you: if you’ve got your heart set on a surf in the Swanage area over the next couple of weeks, you’re going to need a lot of patience. We’re looking at a long, quiet run here.
To be honest, this is a pretty bleak stretch. Swanage is a very sheltered spot and, true to form, we’ve got a big ol’ gap of almost nothing surfable. For the first ten or eleven days, there’s just no swell of any real use. You’ll see small bumps here and there, but the energy is weak, and the conditions aren’t coming together. It’s a proper blank run for the area. That said, forecasts can change, so don’t bin the board.
Now, if we jump all the way to Sunday the 30th of August, there’s finally a flicker of life. The morning looks like the best shot we get in the whole 16-day window. We’ve got a 3ft southwest swell pushing in, with a clean light offshore wind from the west-southwest. The combined energy finally hits the moderate range at 101, which is the only real pulse we see. The wave period is only 7 seconds, so it’s a short-period wind swell, nothing to write home about, but after weeks of nothing, it’s the standout simply because it’s the only game in town. The water temperature is sitting at a very unusual 69°, which is much warmer than normal for this time of year.
There’s no other break to compare it to. This is the one. It’s not going to be a world-class session, but for a clean, small-wave cruiser on a Sunday morning, you could do worse. Just don’t expect much, and you might enjoy it.
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.
