The Lowdown
Alright, Rusty here again, breaking down the Swanage beach for you in feet, miles per hour, and Fahrenheit.
Honestly, looking at the full 16-day picture, it’s a pretty rough stretch. There’s no proper, rideable surf on the cards. Most days have the wind blowing either across the swell or just hammering it too hard, and the wave quality is just not there for a good paddle-out.
The first possible something pops up on Sunday, August 30th, but it’s a no. The morning has about 4ft of SW swell, but the cross-off wind is blowing a strong 16 mph, making it sloppy, and the combined energy is only moderate at 243. It’s a zero on the scale. The afternoon brings a risk of thunderstorms and even stronger wind, so forget it.
Monday, August 31st is the best you’ll see all period. The morning shows 6ft from the WSW with an offshore wind from the west at 19 mph. The energy is strong (520), but the condition is still described as “poor.” It’s just not clean. The afternoon drops to 4ft with a lighter offshore, but it’s only a 1 out of 10 – you could catch a few, but they’ll be ordinary. That’s your one window, and it’s not a standout.
After that, it goes flat and useless. Tuesday, September 1st drops to just 2ft of short-period mush. The rest of the week has a lot of either zero swell or little 0.7ft dribble with messy winds. On Thursday, September 3rd, you get a bigger 7ft swell, but with a super short period of 7 seconds and a strong cross-off wind, it’s just a washed-out mess.
In the second week, Tuesday, September 8th has some size again, with 6ft in the morning and a bigger 8ft in the afternoon from the SSW. The energy is very strong (734), but the cross-off wind is blowing 19 mph and the quality is still zero. That size with that wind will be lumpy and ugly.
Later on, Friday, September 11th shows 6ft of WSW swell, but with a 6-second period and a clean cross-off, it’ll be too short and fat to do much with.
Bottom line: there is no true highlight in this 16-day window. The only time you could possibly get in the water is the morning of August 31st, and it’s a “ordinary” day at best. For Swanage, which needs a very specific angle of swell and light winds, this kind of long, quiet stretch is not unusual. The forecast can always change, but right now you’re better off leaving the board at home.

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.
