The Lowdown
Right then, let's have a look at the forecast for the next couple of weeks. To be honest, it's a pretty quiet picture for Swanage. The whole 16-day window is a bit of a dud, with no real surf on offer. The water's sitting at a very warm 69°, which is a full 7° warmer than usual for this time of year, so you'll be swimming in a bath, but you won't be surfing.
The first few days, from Tuesday the 11th right through to Saturday the 23rd of August, are all marked as "poor surf conditions" with scores of zero. It's a long stretch of flatness. The swell energy is weak, barely cracking 100 on the gauge, and when there is a little bump, it's short-period windswell. The best we see is a tiny 3 ft swell on the Saturday morning of the 22nd, but the period is a pathetic 6 seconds, so it won't have any push. The winds are often onshore or cross, making things messy. There's a few sessions with offshore winds, like the Friday afternoon of the 14th, but with zero swell energy, it's just a clean, flat ocean.
Later in the window, around the 24th and 25th of August, there's a tiny bit more activity, but it's still hopeless. The combined energy only gets into the double digits, and the swell heights are still under 2 ft. The wind is often offshore, but if there's no swell to work with, it doesn't matter. This is a classic case of a blank run for the area. It's a very sheltered spot, so it tends to go quiet for long stretches. No paddle surfing to be had here, I'm afraid. The best advice is to leave the board in the car and go for a swim.

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.
