The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one for Swanage. The whole 16-day window is looking pretty grim for surf. We’ve got a long stretch coming up with no real swell to get excited about.
The first sprinkle of energy shows up on Tuesday, September 8th, with a tiny 1ft swell from the WSW, but the wind is a fresh 22 mph cross-offshore, so it’s not going to be any fun. The water is a notable 68°F and the anomaly is a massive 6°F warmer than usual, which is very unusual for this time of year.
Things don’t improve much. The rest of the first week and into the second is a series of small, weak swells, mostly under 3ft, with poor conditions. The water is warm, but it’s a washout.
The only real chance to get wet comes on Friday, September 11th. The morning brings a 5ft swell from the WSW, with a moderate 12 mph cross-offshore wind. The combined energy is moderate (377). It’s the biggest swell of the whole run, but it’s still going to be pretty ordinary. The break is Swanage itself, which is rarely breaking and very sheltered. The afternoon sees the swell drop to 3ft with a clean offshore wind, making it surfable, but nothing to write home about.
After that, it’s back to flatness. The next potential bump isn’t until Tuesday, September 22nd, with a 4ft easterly swell, but it’s coming with a solid onshore wind, making it choppy and poor. Combined energy is moderate (125), but the wind is a buzzkill.
In short, if you’ve got a kite, you might find some fun on the windier days, but for paddle surfing, this is a 16-day blank. It’s a normal run for this area – it tends to stay poor for a while, but forecasts can change.

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.
