The Lowdown
G’day, I’m Rusty. Looked at Swanage for the next 16 days, and it’s a lean run. This spot only rarely breaks and it’s very sheltered, so the surf window is small. Let’s talk about what’s on offer.
It starts Saturday the 29th of August, but it’s a mess—a 10ft SW swell with heavy energy (1276), but 31 mph winds ruin it. Sunday the 30th has a 4ft SW swell (243) with moderate breeze, still poor conditions. Monday the 31st is the best of the first week: a 6ft WSW swell (429) with clean, fresh offshore wind from the west at 19 mph. That’s the standout—clean faces, decent size for experienced surfers, but over 5ft it’s a bit much for groms. Period is 9 seconds. Crowds are sometimes a thing.
After that, it drops off. Tuesday through to Saturday the 5th of September, it’s tiny or flat—waves under 2ft with energy under 183. Sunday the 6th has a 0.7ft WSW groundswell with a very long 10-second period, but energy is almost nothing (9). There’s a gap of several days with no real surf.
Second week is even quieter. Monday the 7th to Saturday the 12th, we get waves from 0.7ft to 3ft, all poor conditions, energy under 100. Friday the 11th has a 1ft WSW groundswell (100) with strong offshore winds (19-25 mph), but it’s tiny and hard to paddle into. Sunday the 13th shows a 1ft SW groundswell with a very long 17-second period (69), but again poor. Water temp is about average for this time of year.
Your best bet is Monday the 31st of August morning—clean offshore wind and a 6ft WSW swell. Other than that, you’re waiting on a change.
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.
