The Lowdown
Alright, Rusty here. Let's have a look at what's cooking for Swanage, but I gotta warn you, it's looking pretty grim. The charts are showing a real desert for the next two weeks.
The main problem is the swell is tiny, and the wind is all over the place. Conditions are marked as poor all the way through. For the first week, from Saturday the 8th through Friday the 14th, we're looking at knee-high dribble best. The wave energy is pitiful, mostly single digits (1 to 6), and even the "biggest" pulse on the 12th only hits 103 (moderate energy), but it's a short-period, onshore mess. It's just not worth paddling out.
The following week, from the 15th to the 23rd, offers a bit more wind, but the swell is still missing. We get a few clean offshore days, like the 17th and 19th, but the swell is still only 0.7ft to 2ft with very weak energy (2 to 50). The surf is just not there. There's a brief moment on the 20th with glassy conditions, but with a 0.3ft, 9-second swell and energy of 4, it's a flat calm, not a surfable wave.
The best bet in this whole 16-day window is a very, very small window. On Thursday the 14th, the afternoon session shows a 2ft swell from the WSW with a 9-second period, and importantly, a moderate offshore wind from the WNW. That's the cleanest the surf will be, but you're still looking at ankle-biters. The wave energy is only 45 (very weak). It's not a standout, it's just the least bad option.
Given the lack of any consistent swell, a blank run like this is more normal for this area. It's a quiet time of year. We'll have to wait for the forecasts to change.
That's all I've got for Swanage. Keep your eyes on the horizon.
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.
