The Lowdown
Alright mate, let’s talk Swanage. Honestly? It’s a rough outlook. You’ve got almost nothing on the table for the next 16 days. This is a sheltered break that barely breaks on a good day, and this stretch is dead.
Right from Sunday the 13th, it’s a no-go. Monday the 14th shows a tiny 2ft westerly swell at 9 seconds, energy is weak at 41, and it’s still labelled poor. Tuesday and Wednesday are small—0.3ft to 2ft—with mixed periods but no power. Winds are offshore or cross-offshore at times, which would be nice, but there’s no swell to surf. Thursday the 17th is flat.
Friday the 18th gives you a 0.7ft swell with a 15-second period—super long period for a wave that size. At a beach break, long period swells this small just roll straight through. Energy is only 22 (weak). Saturday the 19th is the same story with clean offshore wind but barely a ripple.
Sunday the 20th morning has glassy conditions with winds at 3 mph from the WNW, and a 0.7ft southwest swell. Clean as can be, but it’s still tiny. Not surfable.
Into the second week, there’s a bit of a bump on Wednesday the 25th: 4ft easterly swell, 6-second period. Combined energy hits 104 (moderate). But it’s cross-onshore and onshore, short period windswell with chop. That’s not a surfable wave. At 4ft it’s not huge, but it’s messy. Honestly, this looks better for kite surfing than paddle surfing.
After that, it fades back to almost nothing for the rest of the month. The water temp is about 67°F, which is 3°C above average—very unusual and much warmer than normal, but that won’t help the waves.
So no standout sessions. A blank run like this is pretty normal for a sheltered spot like Swanage. Forecasts can change, but I wouldn’t hold my breath.

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.
