The Lowdown
Alright, mates, let's not beat around the bush. If you're checking the surf for Swanage, you better pack a book, because there's not much happening. For the next fortnight, we're basically looking at a whole lot of flat and tiny, messy dribble. It’s going to be a serious test of patience.
The first solid bit of surf we see is on the 29th of August, with a small 4ft to 4ft bump. It's got clean offshore winds, but it's a short-period wind swell, so it'll be weak and likely pretty crumbly. Then, on the 31st, there's a touch more size at 5ft in the morning with a clean cross-off breeze, but it's still not going to be anything special.
The only real standout is on Tuesday, the 1st of September. That afternoon we should see 6ft of swell out of the southwest. It's got a short period, but the energy jumps up significantly. The winds are light and cross-shore, so it won't be glassy, but it's the most powerful surf we've seen. This is a good day for intermediate surfers. It's still a beach break, so with that short period, it might wall up and close out in sections. But it's the best we've got. Go get some.
It's a frustrating forecast, but this spot is known for being fickle. It doesn't handle small swells well. But when a real swell hits, it can turn on. We just need to wait for the forecast to change.
Rusty out.

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.
