The Lowdown
Alright, this is Rusty comin' to you from the shores of Swanage. Gotta be straight with you – it’s lookin’ bleak. Real bleak. We’re staring down a 16-day stretch where the ocean just isn’t playing ball. The first surfable wave I can even talk about isn't until Monday the 31st of August, and even then, it's not good.
We've got a run of no recommendations at all. The swell is either flat or so weak it's barely a ripple, and the wind is mostly cross-off or howling onshore. There's a small pulse on the Monday morning, with 6 ft swell from the WSW, and the combined wave energy is moderate at 523. But the wind is a fresh offshore from the W, so it will be clean. The problem is the quality is still rated poor – it's just too junky. The water is much warmer than normal at 69°.
Later that Friday, the 4th of September, there's another little bump – 5 ft from the WSW with a period of just 6 seconds. That's short-period, wind-choppy stuff, and while the wind is offshore, it's a fresh breeze. Combined energy is moderate at 210, but it’s not going to be any kind of classic.
Honestly, the only real standout in this whole sorry outlook is a moment of glass. On Saturday the 12th of September, the morning shows a flat calm with the wind at 0 mph. The swell is a pathetic 3 ft from the WSW, and the combined energy is weak at 95. It's not gonna be big, but with the wind going glassy, any little bump that rolls in will be as clean as a whistle. It’s about the only time you might get a fun little crumble to yourself, because crowds are sometimes an issue here, but I doubt many will bother for this.
For the rest of the two weeks, it's a whole lot of nothing. Swells under 2 ft, weak energy readings in the single digits or low tens, and cross-off or onshore winds. There's a moment on the 8th of September with a strong offshore breeze at 25 mph, but with no swell to speak of, it's just a strong, clean wind over a flat ocean. A kite might fly, but a surfboard won't.
It’s a rough patch. The lack of consistency is the real story here. We’ll just have to hope the forecasts change.
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.
