The Lowdown
Alright, Rusty here again for the imperial heads. Let’s size it up.
First off, the water is feeling like a hot tub right now—much warmer than normal at about 69°F. That’s over three degrees warmer than what you’d usually get at this time of year.
Looking at the whole 16-day forecast, it’s a dry spell for surf. We start with nothing worth paddling for. The first real chance doesn’t come until Monday the 31st of August. That morning, Swanage has a 5ft swell from the WSW, with fresh offshore winds out of the W. It’s clean, but the period is short at 9 seconds, and the combined energy is only moderate at 346. It’s the best you’ll see for a while, but it’s not exactly firing.
Then nothing again for days. Tiny, weak swell with cross-off winds. The next highlight is Monday the 7th of September morning. A solid 8ft swell from the WSW rolls in with a short 7-second period. Combined energy jumps to 687, so there’s power there. Wind is a light cross-off from the NNW. It’s messy—more of a kite-surfing day than a clean paddle session. That’s expert-only size, too.
After that, it’s back to scraps. The 4th of September afternoon has a tiny 0.7ft swell but a long 12-second period with a fresh offshore—barely enough to ride. Everything from the 8th onward is flat or close to it.
So, for the whole window, Monday the 7th of September is your best bet if you’re an experienced surfer, but don’t expect perfection.
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.
