The Lowdown
G'day, I'm Rusty.
Alright, look, if you’re surfing Swanage, you know the drill. It’s a very sheltered spot and, to be honest, the next 16 days are a real struggle. There’s barely a wave to get excited about. We’ve got a long dry spell from right now, through Friday the 11th, and it doesn't really change for over a week. You're looking at a whole lot of nothing until the 19th of September, and even then, it’s nothing special.
Let’s break it down. Friday the 11th is a write-off. Tiny 3 ft swell from the SW, a weak energy reading of 47, and it's just poor. The afternoon has a bit more juice – 3 ft from the WSW with a moderate energy of 212 – but it’s still ordinary. A 9-second period and offshore wind, but the wave quality just isn’t there. Saturday and Sunday are even worse, dropping to knee-high dribble or flat.
The whole of the following week, from the 14th to the 18th, is dead. We’re talking essentially flat surf every day, with energy readings mostly below 40, and the wind is either cross or cross-off. Don’t bother.
Now, the 19th of September, Saturday morning, finally offers something. A 6 ft swell from the SW, a moderate energy of 263, and a clean look with light offshore wind. The period is a short 7 seconds, so it’ll be a bit jumbled and fat, but for Swanage, that’s actually the biggest and best-looking window in the whole forecast. The afternoon drops off though.
The 23rd of September, Wednesday, is another sniff. Morning shows 7 ft from the WSW with a moderate energy of 342 and a clean, glassy feel. That’s the biggest swell of the period, but again, it's a short period at 7 seconds. For a spot that rarely breaks, the fact that it's starting to pump is notable. It might actually be rideable.
Honestly, for the whole 16-day run, the only two standouts are Saturday the 19th morning and Wednesday the 23rd. The 19th has a better wind, the 23rd has a bit more size. If you’re a complete beginner, that 7 ft on the 23rd might be a bit of a handful, but for everyone else, that’s your best chance to get a wet suit on and actually surf something.
Everything else is flat, windy, or both. It’s a tough stretch, mate. Forecasts can change, but right now, it’s looking like a long, slow grind.
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.
