The Lowdown
Alright, Rusty here. Let’s be honest, this is a tough stretch ahead. Looking at Swanage over the next couple of weeks, the pattern is one of persistent small, weak, and frankly poor surf conditions. There are no standout swells that will offer anything remotely decent, and most days are simply flat or close to it. You're looking at a long period of small, wind-affected waves or very low energy that just won't produce any rideable face.
For the first week, from Tuesday the 8th through to the end of the following weekend, the swell stays tiny, mostly around 0.3 ft to 3 ft. The combined energy is very weak, with values mostly between 4 and 146 (146), but that's more a reflection of short-period wind chop than real swell. Winds are often cross-off or offshore, which would be great for clean conditions, but with no swell to work with, it's pointless. The water temperature anomaly is pretty much average for this time of year.
The only even notable bump in the whole 16-day window arrives on Monday the 21st of September. A windswell pushes up to 4 ft from the East, with a short period of 6 seconds. The energy jumps up to 161 and 194, which is moderate, but that's a messy, short-period groundswell from a poor direction. That wave will be closing out and choppy, and with a brisk 25 mph offshore wind, paddling out will be a battle. It's still scored as "poor surf conditions" and really only something for the most dedicated or for kite surfers, not for a proper paddle session. The break itself, Swanage, is very sheltered and rarely breaks, so this stretch of nothing is not a surprise for the area.
After that, it fades back to flat surf through the 23rd. Honestly, there’s nothing here to get excited about. The boards stay in the truck. 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.
