The Lowdown
G'day, Rusty here. Look, I've scoured the charts for the next couple of weeks, and I gotta be straight with you—it's a tough run for surf at Swanage. The swell window's just not cooperating, and we're staring down a long, dry spell. Most of the time we've got next to nothing, and when there is a tiny pulse, the winds are often messy. There's a good string of days with nothing rideable from the 12th right through to the 19th of September, so don't bother waxing up for a while.
The first real chance of anything more than a ripple comes on Sunday the 20th of September, but it's a weird one. A sudden jump in swell to 7ft from the WSW, but with a period of only 6 seconds—that's pure windswell, all chop and no push. The combined energy hits a moderate 309 (moderate wave energy), but with those short, weak waves on a beach, it won't be pretty. Conditions will be messy too with a cross-off breeze. Honestly, for the experienced crew with a big board and a lot of patience, you might get a few closeouts. For anyone else, this setup is more interesting for a kite session than a paddle session.
The rest of the run is a total bust. The morning of Monday the 21st of September gives us a tiny 2ft from the WSW with a period of 5 seconds, with a gentle offshore wind. The energy is only 31 (weak wave energy). It's barely a ripple. Then we get a couple of glassy mornings on the 22nd and 23rd, but the swell is just not there—0.7ft and 0.3ft respectively. The water's about 67°F and the anomaly is 6°F, which is *much* warmer than normal for this time of year—unusually warm water for the kids to splash in, but no surf to be had.
There's absolutely nothing to get excited about in this 16-day outlook. Swanage is a very sheltered, rarely-breaking spot, and this forecast shows exactly why. Hang tight, and check back with me next week; it's gotta turn around eventually.

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.
