The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a grim outlook for Swanage. We’re looking at a full 16-day window and there’s simply nothing worth paddling out for. The whole run is a write-off.
The first sniff of any swell shows up on the morning of Sunday the 9th, but it’s a pathetic 1ft from the east with a short, weak period of 4 seconds. The combined energy is a measly 7, and it’s crossed up by a light onshore breeze. It’s poor, and it stays poor. The next few days don’t offer any real hope either. Monday morning shows similar tiny 1ft swell from the southwest, but with a cross-shore wind, it’s not going to clean up into anything rideable.
We get a bit of a spike on Tuesday the 11th, with swell hitting 4ft from the east, but the period is still short at 5 seconds and the wind is howling directly onshore at 19 mph. That’s just messy, blown-out junk. The combined energy climbs to 88, but it’s all wind-chop. Wednesday and Thursday are more of the same – onshore winds and poor conditions. This setup actually looks more interesting for kite surfing than paddle surfing, to be honest.
After that, it’s a long, flat gap. From the 14th onwards, the swell drops off to barely a ripple, with heights hovering around 0.3ft to 0.7ft for days on end. Winds are a mixed bag, but it doesn’t matter because there’s no wave energy to work with. The combined energy values are mostly single digits, which is about as weak as it gets. Even the glassy morning on Monday the 17th with that tiny 0.3ft groundswell from the west isn’t going to produce a wave you can ride.
Late in the month, on the 23rd, we see a long-period 14-second swell from the south, but it’s only 0.3ft. The energy is just 7. It’s a tease. Monday the 24th is the same story – a 0.3ft, 13-second south swell with a clean cross-offshore breeze. But with no size, it’s a flat spell.
The bottom line: Swanage is notoriously sheltered and rarely breaks, and this outlook is a perfect example of why. For a spot that’s this inconsistent, a blank run like this is more normal than unusual. Don’t hold your breath – forecasts can change, but right now, there’s not a single wave to chase.
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.
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.
