The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s happening for Swanage. Gotta be straight with you – it’s a tough stretch. This spot is very sheltered and rarely breaks, and this forecast is a long, quiet run. Right now, the water is 68.9°, which is much warmer than normal for this time of year – that’s a solid 6.8° above average, pretty unusual.
First up, we’ve got a gap of nothing worth paddling for. The first sniff of anything is on the morning of Thursday, 28 August. We see a small 2.6ft swell out of the SW, but the wind is a clean cross-offshore. The combined energy is weak (112), and honestly, the conditions are still rated poor. Not one to get excited about.
Moving into Friday, 29 August, the swell bumps up to 7.9ft from the SW with a short period of 7 seconds. The wind stays cross-offshore, but it’s howling at 25 mph. That’s strong breeze territory. The wave energy is moderate (541), but that wind is going to make it a messy, blown-out mess. This is more of a kite-surfing setup than a paddle session.
Saturday, 30 August, is similar. The swell drops to 4.6ft, still SW, but the wind is 19 mph and cross-offshore. Energy is moderate (420), but the quality isn’t there. Still looking poor.
The most interesting blip is Saturday, 5 September. There’s a 9.8ft swell from the SW, period 8 seconds, with a fresh offshore wind out of the WSW. The combined energy is strong (967). This is the biggest swell of the window, but at 9.8ft, it’s only for experienced surfers. The offshore wind will keep it clean, though. It’s a marginal call due to tide or conditions, but if you’re an expert, this is the one to watch.
Beyond that, the rest of the forecast is weak or flat. By Monday, 8 September, we’re back to tiny bumps. It’s a long, quiet outlook for Swanage.
Stay patient, lads. The ocean will turn around.

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.
