The Lowdown
Alright folks, Rusty here. Let’s chew the fat on what’s happening at Swanage for the next couple of weeks.
I’ve got to be honest with you, it’s a slow start. The first real chance of a surf doesn’t show up until Wednesday, the 16th of September, so we’re looking at a solid ten-day gap of flat, tiny, or just plain poor surf. That’s a long, dry spell.
The first glimmer of hope comes on Wednesday morning, the 16th. We’ve got a wave height of about 8 feet out of the WSW, but the period is a short 7 seconds, so it’s going to be a bit lumpy and weak. The energy is moderate (553), but it’s solid enough to get out on a bigger board. The wind is light and cross-offshore, so it’ll be clean. This is one of the only windows where the size is worth paddling for, but at 8 feet, it’s a handful—really only for the experienced crew. This spot is a very sheltered one that rarely breaks, so seeing it hit this size is a bit of a novelty.
The afternoon of the 16th holds a little better. Same 8-foot swell, still WSW, and the wind swings to a gentle offshore. The energy jumps up a notch (730), making it the strongest pulse of the whole period. For a spot that’s normally quiet, this is your best bet, but again, it’s expert territory with that height.
After that, the rest of the period is a letdown. Thursday the 17th morning offers a 5-foot swell, but again, short period (6 seconds). The energy is moderate (192) and the wind is light offshore, so it’s clean, but it’s not a classic wave. The next standout is Friday the 18th, with a 6-foot to 8-foot swell from the WSW, but the period is still short (6-7 seconds), so it’s a bit fat and weak. The energy is moderate to strong (258 and 527), but the conditions are just ordinary.
If you’re keen, the 16th is the only day that’s really worth a look. For the rest, it’s a case of waiting for a change in the pattern. It’s a blank run that’s pretty normal for this area at this time of year.
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.
