The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough stretch for surf around here. We’re looking at a 16-day window with a whole lot of nothing good on offer.
The first shot at anything rideable doesn’t show up until Wednesday the 16th, and it’s a real whisper. You’ll see a little bump of 1 ft from the WSW with an 8-second period, and the combined swell energy is a weak 26. That’s not enough to get excited about.
The only spot we’ve got to look at is Swanage. It’s a very sheltered setup that rarely breaks, so you’d be waiting on a near-miracle. Even the best day of the period – Wednesday the 16th afternoon – only lifts to a 2 ft swell from the WSW, with a slightly better 11-second period. That’s still a fairly clean look with a moderate offshore wind, and combined energy up to 147. It’s surfable for a longboard or a foamie on the inside, but it’s not going to light anyone’s world on fire. Conditions are pretty average for the time of year temperature-wise.
Thursday the 17th sees a brief push of 5 ft, but that’s a short-period, junky 6-second swell with a stiff 19 mph offshore wind. It’ll be bumpy and close out fast – not a good look for paddle surfing. With that kind of wind and a beach-break vibe, you might see a kite surfer having more fun than any of us.
After that, it’s back to tiny or flat waves for days on end. We’re talking 0.3 ft to 0.7 ft from the 18th right through to the 25th. There’s a tiny pulse on the 26th – 4 ft from the east with a 5-second period – but that’s onshore wind and choppy conditions, so no thanks.
Honestly, this is one of those blank runs that’s pretty normal for this area. The swell window is just too tight. We don’t have a single standout session in the whole 16 days. Forecasts can change, but right now, I’d say leave the board in the car and go for a walk.
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.
