The Lowdown
Alright folks, Rusty here. Let's be straight with you – we’ve got a long stretch ahead with very little to get excited about at Swanage. This is a sheltered setup, and it rarely breaks, so when the charts look like this, it’s a pretty normal blank run for the area. We’re looking at a 16-day window where the first recommendation is sparse, and there are long gaps of days with absolutely nothing rideable.
The pattern is pretty grim. We start on Friday morning, 7th August, with a tiny 0.7 ft swell from the WSW and a period of just 5 seconds. The combined energy is a weak 7, and it’s classified as poor surf. The water is a balmy 69°, which is a massive 7° warmer than usual for this time of year – that’s very unusual. The wind is a light 3 mph cross-offshore, so it’s clean, but with no height or period, there’s nothing to ride.
The rest of the first week and into the second is a total write-off. We’ve got days of flat, glassy conditions with no energy, or onshore wind with weak, short-period slop. You’ll see a blip on Tuesday the 11th with a 4 ft to 4 ft swell from the east, but it’s coming straight onshore with a 19 mph wind, and the period is a pathetic 5 to 6 seconds. The energy gets up to 107 (moderate) on the afternoon, but the wind state is "unknown" because it’s probably just a churned-up mess. That’s more of a kite session than a surf session.
The only real standout, and I’m using that term loosely, is Thursday morning, 20th August. We’ve got a 5 ft swell from the WSW with a 6-second period. The combined energy hits 187, which is solid moderate energy. The wind is a clean 12 mph cross-offshore from the NNW. That’s the biggest swell of the whole period, and it’s clean. At 5 ft, it’s on the edge of being too much for a beginner, but for anyone else, it’s the best we’ve got. The period is short, so it’ll be a bit fat and crumbly, but it’s surfable. After that, it drops right back off into nothing.
So, if you’re desperate, pencil in the 20th of August for a session. The rest of the time, you’re better off checking the forecasts again because this one is a long, quiet stretch. Hang tight, it won’t stay this poor forever.
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.
