The Lowdown
Right then, let's have a look at what Swanage has got cookin' over the next couple of weeks. Gotta be straight with ya, it's a tough watch for most of it. The first week and a half is pretty much flat as a pancake, with nothing worth paddling out for. We're talkin' tiny dribbles of 0.3ft to 1ft with next to no energy behind 'em. The wind's mostly messy or just wrong, and combined energy readings are barely a whisper, numbers like 1 or 5 (combined energy of all swells directed here). It's a real quiet spell.
Then, out of nowhere, we get a bit of a pulse. On Sunday, July 26th, the swell finally shows up. The morning kicks off with a clean 6ft from the WSW, and it builds through the day. By the afternoon, it's a solid 7ft from the SW with a moderate offshore wind making things clean. The wave energy jumps right up to 400 (combined energy of all swells directed here). Now, this is proper size. Over 5ft, so it's leaving the beginners on the beach, and at 7ft, this is one for the experienced crew only. It's a short-period windswell though, only 7 seconds, so it won't have the same grunt as a groundswell, but it's the only real action in the whole window. Swanage is a very sheltered spot and rarely breaks, so to see this much size is a real novelty.
After that little burst, it drops straight back down to nothing again for the rest of the run. More 0.3ft dribbles and blank days. The water temp is about average for this time of year, nothing unusual there.
So, the honest truth? There's one day, Sunday the 26th, that's the clear standout. Get on the 7ft afternoon session if you're an expert and hungry for it. For everyone else, this forecast is a write-off. Keep your eyes peeled, though—forecasts can always change for the better.

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.
