The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. The next 16 days for Swanage are a proper test of patience. The forecast shows a big gap right at the start, with nothing worth paddling for until at least the 17th of August. That’s a stretch of nearly two weeks with no real surf on offer. The good news is that after that wait, there’s one day that looks like it could finally deliver.
Let’s start with the reality of the next few weeks. From Wednesday the 5th through to the 16th, it’s a write-off. The swell is tiny, the wind is nearly always wrong, and the wave energy is pathetic. The water is sitting at a very unusual 69°F – that’s 7°F warmer than normal for this time of year, which is a real oddity, but it won’t help the waves. The crowds at Swanage can be an issue sometimes, but you won’t need to worry about that for a while.
Now, hold on to your leashes, because Monday the 17th of August is the standout. The morning session is the play. The combined energy of all swells directed here hits 894 (moderate wave energy), coming from the WSW at 10ft with a period of 8 seconds. That’s a solid, chunky swell. However, 10ft is only for experts; it’s going to be a heavy, powerful beast. The wind is WNW at 16 mph, which is a cross-offshore breeze, keeping the surface clean. The afternoon stays good with a 7ft WSW swell and the wind switching to a proper offshore from the WNW at 19 mph, making for some proper, clean-faced waves. The period is short at 7 seconds, so it’ll be a bit crumbly, but the power is there. That’s the one day to circle on the calendar.
Before that, on Wednesday the 12th, there’s a sniff of something with a 4ft ESE swell, but the wind is howling onshore from the East at 19 mph. That’s going to be a choppy, blown-out mess, and with that short period, it’s really more of a kite surfing session than a paddle-in.
Bottom line: don’t bother checking the charts until the 17th. That Monday in the second week is your best and only real shot. It’s a long way off, so keep an eye on it, but it’s the one that could break the drought.
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.
