The Lowdown
Alright folks, Rusty here with a look at what’s coming up for us over the next couple of weeks.
Honestly, looking at the charts, it’s a tough stretch ahead for Swanage. We’re looking at a whole lot of flat, weak days. There’s nothing really rideable for over a week. The first solid pulse of energy doesn't show up until Thursday the 17th of September, so you’re looking at a solid 10-day gap of poor conditions before anything gets going.
The highlight of the entire forecast, and the only real standout, is the morning of Thursday the 17th of September. We get a sudden jump in energy with a combined swell energy of 865 (moderate to strong). It’s a 8ft swell from the WSW, but with a short period of only 8 seconds. That size is going to be too much for beginners and is really only for experienced surfers. On the plus side, the wind is a fresh offshore from the WSW, which should keep the surface clean. The swell direction is from the SW, which matches the optimum for Swanage.
After that, the energy drops off quickly, and the following Saturday the 19th of September morning sees another pulse, this time 8ft from the SW with a 7-second period. Again, that’s expert territory due to the size. It will be clean with a moderate offshore wind, but the period is so short it might be a bit of a washing machine.
Before that, there’s just nothing doing. The swell is tiny, the energy readings are all two-digit numbers (weak) or zero, and the conditions are all described as poor. A few days have some offshore wind, but with no swell to work with, it’s a moot point.
So, the takeaway is this: don't get your hopes up for the first week and a half. The only real shot at a wave is on the 17th of September, and that's for the big-wave crew only. For the rest of us, it might be a good time to check the tide pools or take up a different hobby for a bit. Forecasts can change, but this is a long blank run.
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.
