The Lowdown
Alright, Rusty here. Let’s be straight with you—this is a tough outlook for Swanage. We’re looking at a 16-day window and honestly, the surf is mostly a no-show. We start with a big gap of nothing worth paddling out for. The first hint of anything rideable doesn’t pop up until Friday the 11th, and even then, it’s a struggle.
There’s a brief moment on Friday afternoon, the 11th of September, where we get a bump of swell. The waves are around 3ft coming from the WSW with a period of 9 seconds, and the wind is blowing offshore. It’s clean but the energy is only moderate (228). It’s surfable, but very ordinary. You might get a few, but don’t expect much.
Saturday the 12th is a write-off. The swell drops right off. Sunday and Monday stay small and weak. The following week is more of the same—tiny, weak, and mostly unsurfable. The water temperature on the 10th is 68°, which is much warmer than usual for this time of year, a full 6° above normal, so that’s a weird one, but it won’t help the waves.
Honestly, the only thing that even catches my eye is way out in the second week. On Wednesday the 23rd of September, a short-period swell shows up late in the day, pushing to 6ft from the WSW with only 6 seconds between waves. The energy is moderate (241), but the wind is light and cross-onshore. That combo is messy. For a sheltered spot like Swanage, a short-period swell this size will be a mess of close-out chop. It’s more interesting for a kite surfer than a paddle surfer. For the rest of the window, it’s flat or near-flat.
This is a blank run, and for this area, it’s not that unusual. It tends not to stay poor for long, and forecasts can change, but right now, there’s nothing to get excited about.
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.
