The Lowdown
Alright, surfers, Rusty here. Let's be straight with you: the next couple of weeks at Swanage are looking pretty bleak. The swell is tiny, the energy is weak, and we're staring down the barrel of a long flat spell. There's nothing on the cards for the first week, and the outlook beyond that doesn't offer much hope either. It's one of those periods where you might as well tune up your fishing gear or take up hiking.
The first real day worth mentioning is Wednesday the 12th of August. We've got a tiny 3ft swell rolling in from the east, with a period of just 5 seconds. That's short-period wind chop, not groundswell. The combined energy is a weak 47, so it's barely got any push. The morning wind is offshore from the west at 12 mph, which will keep it tidy, but honestly, it's ankle-to-knee high at best. It's a beginner-level wave, but it's a long way from being surfable.
After that, the trend continues with nothing but small, weak pulses. Thursday the 13th of August has a 1ft swell from the WSW with a 9-second period and glassy conditions in the morning, but the energy is only 32. It's a clean, flat lake. The following days are more of the same – tiny 0.7ft to 2ft swells, mostly with short periods, and the wind is either offshore or cross-off, but there's just no size to work with.
The best of a bad bunch might be Sunday the 16th of August, with a 1ft WSW swell and a 9 mph offshore wind in the morning, but the energy is a paltry 12. It's barely a ripple. Monday the 17th of August has glassy conditions in the morning with a 1ft swell, but again, it's a 25 on the energy scale. These are all flat days.
The long-range forecast, out to Friday the 21st of August, shows nothing that changes the story. The swell heights stay under 2ft, the periods are short, and the wind, while often offshore, can't make up for the lack of waves. The combined energy never gets above 35. This is a dead period for surfing.
So, there's no standout session. No good options. The water temperature is about average for the time of year, but you won't be getting wet for a wave. Keep an eye on the charts, but for now, Swanage is a write-off.
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.
