The Lowdown
Alright, let's check the score for Swanage. It's a bit of a grim picture for the next couple of weeks.
The water is a weirdly warm 69°F, much warmer than usual, but that's the only highlight. The swell is flat, the wind is all over the place, and the spot is real sheltered. There's a big, dry gap from the start, with nothing worth paddling out for for over a week.
The first real chance of anything comes around the morning of the 11th of August, when a small 4ft easterly windswell shows up, but with onshore wind it'll be a messy close-out. The energy is weak, just 80 (moderate wave energy). The spot is inconsistent and rarely breaks, so you're just waiting on a prayer.
The best window is looking like the morning of the 20th of August. A solid 6ft swell from the SW rolls in, with a combined energy of 255 (moderate wave energy). The period is a short 6 seconds, so it's a choppy windswell, not a clean groundswell. The wind is a light cross-onshore, not perfect but workable. That's a decent size, but with the short period it won't be heavy, though it could be a bit much for the total beginners. It's the best on offer, but it's a long way out.
The 18th of August has a gusty 3ft swell with fresh offshore winds, which will be clean but small. The 13th afternoon has a clean 3ft with a moderate offshore breeze, but again, it's small.
If you're real keen, the 11th and 12th have some small easterly swell, but the onshore wind will ruin it. Nothing here is a proper standout. It's a real dry spell for this area.
Signing off, 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.
