The Lowdown
Alright folks, Rusty here. Gotta be straight with you – Swanage is locked in a proper summer flat spell. Looking through the whole 16-day window and there’s nothing here I’d call a surf. It’s a long, quiet stretch.
The place barely breaks as it is, and right now there’s just nothing doing. We’ve got a run from now until the end of the month that’s almost entirely flat, with barely a ripple showing up. The water temp is sitting at a very unusual 69°, much warmer than normal for this time of year, but that’s small comfort when there’s no waves to enjoy.
Monday 28th of August sees a spike in energy – a swell from the SW at 6ft with moderate energy (344). But that’s coming with onshore wind from the east, so it’ll be lumpy and messy. Poor conditions all round. That same energy drops to 5ft on the Monday afternoon and the wind stays cross-onshore, so still no good. For a spot that’s very sheltered and only rarely breaks, this is a classic summer blank run. If you’re desperate for a paddle, maybe, but for surf? There’s nothing to recommend here.
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.
