The Lowdown
Alright, mates, let’s talk about what’s cooking at Swanage over the next couple of weeks.
Right off the bat, things are looking pretty grim. There’s barely any swell to speak of, the wind is blowing strong, and the water’s been feeling way warmer than it should be – the anomaly is nearly 4° above normal, so it’s like swimming in a lukewarm tea. For a sheltered spot like Swanage, everything has to be just right, and it’s just not there yet.
Your first real chance comes on Monday the 31st of August. Early morning there’s a clean 6ft swell from the WSW, with a period around 9 seconds, and a solid offshore wind out of the west. That’s a decent punch of moderate energy (475). It’s not huge, but the conditions are workable. Later in the day the swell drops to around 4ft, and the wind swings, making it feel a bit average. So, Monday morning is your best bet in the first week, and it’s not exactly a classic.
Then we hit a long dry patch. Tuesday through Thursday all show zip or tiny waves. Friday the 4th of September brings a bump: offshore wind, a 8ft swell from the WSW at 7 seconds. But that short period means the waves are weak and crumbly, with moderate energy (603). It might hold for a wave, but don’t expect much.
Now, for the patient crew, the real standout is Tuesday the 8th of September. The swell builds through the day: 10ft in the morning, jumping to 12ft by the afternoon, both from the WSW with a period of 8 to 9 seconds. The energy readings are strong – 1205 and 1724 respectively. That’s proper power. Plus, the wind is offshore from the west at 35 km/h, so it’ll be clean. But look, at 12ft, this is for experienced surfers only. Beginners, stay on the beach. The period isn’t long, so expect steeper, punchier waves that at Swanage can be a handful. If you’ve got the skills, that Tuesday afternoon is the best session in the whole 16-day window.
After that, it all fades into small, messy conditions with onshore winds and rain for the second week, so don’t hold your breath.
Bottom line: Monday the 31st of August morning offers a small, clean window. The absolute standout is Tuesday the 8th of September afternoon – big, powerful, clean, but for experts only. The rest is a waiting game.

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.
