The Lowdown
Alright, let’s get this out there. I’ve been staring at the charts for the next couple of weeks, and I’ve got to be straight with you: it’s a rough stretch for waves around here. The finder is coming up empty for any proper surf. We’re looking at a solid run of nothing, really. For the next week and a half, there’s just no swell of any consequence. You’ll see tiny, weak bumps – we’re talking ankle-biters – not enough to get a proper glide on. It’s one of those blank runs that just seems to sit there, teasing you.
The only time things even get close to interesting is around Friday the 21st and then again on Monday the 24th. On the 21st, we’ll see a pulse of east swell bumping things up to about 4ft, but the period is a short, crumbly 6 seconds. The energy is there, moderate at 116, but it’s a messy, wind-blown kind of thing. The morning has a cross-shore breeze, and even though the afternoon cleans up with a cross-offshore wind, this is still not a quality wave. It’s a beach break, and a short-period east swell is going to be sectiony and hard to ride. With the wind and the junky nature of it, it honestly looks like it might be more fun for the kite crew than us paddle surfers.
Then there’s the 24th, which is a bit of a mirage. The swell height is around 3ft, but the direction is west-southwest, coming from the wrong angle for this spot. The period is still short, 7 seconds, and the energy is moderate at 106. But the morning wind is onshore, and the afternoon is cross-onshore and choppy. Just poor conditions, plain and simple.
So, what have we got? Not a single day where I’d point you to the water and say, “Go get it.” This is a stretch where the jet ski stays covered, and you find something else to do. It might be a good time to check the forecast for further out, because this sort of flat spell doesn’t usually last forever around here. But for now, there’s nothing on the table. Keep the board in the car, but don’t get your hopes up.

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.
Swanage is 13 km (8 miles) from the city of Poole. If you plan a holiday in South Coast of England, look for hotels and other accommodation in Poole. Poole has rooms for a wide range of budgets as well as car hire and transport links.
