The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Swanage over the next couple of weeks.
Mate, I’ll be straight with you: the outlook for Swanage is a tough one. There’s really no surf to get excited about across this whole 16-day run. We’ve got a long stretch of tiny, weak swell, and the few days where the wind is okay, there’s just no push. It’s a proper flat spell.
Looking at the first little blip of energy, Monday the 10th of August morning sees a tiny 1ft swell from the southwest, with a short period of 7 seconds. The combined energy is weak at 18. Wind is a light cross from the north, so it’s not all that clean. Not worth a paddle.
Tuesday the 11th brings the biggest swell of the whole period, but it’s still only 4ft from the east with a very short period of 6 seconds, and the wind is howling onshore from the east at 16 mph. That’s just messy. Combined energy is still weak at 95. This is one to skip.
Wednesday the 12th is more of the same – onshore easterly winds and weak, short-period swell. Not a single standout morning or afternoon in this entire 16-day window. There are a few clean windows with offshore winds, like Friday the 14th morning with a moderate offshore from the west-northwest, but the swell is only 1ft from the west-southwest, so it’s barely a ripple.
For the second week, it’s even more of the same. Tiny dribbles of swell, and mostly clean conditions when there is a puff of offshore wind, but no wave height to work with. The water temperature on the first day we have data for (Saturday 8th August afternoon) is 69°, which is much warmer than normal for the time of year – a notable anomaly of 7° above average.
Honestly, the only thing that might be worth a mention for the more adventurous is if you’ve got a kite. With the onshore easterly winds and that 4ft bump on the 11th and 12th, that setup looks more interesting for kite surfing than paddle surfing.
Keep the board in the car, but don’t hold your breath. It tends not to stay this flat for long, so forecasts could 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.
