The Lowdown
Alright folks, Rusty here. Gonna be straight with you – this is a tough one for Swanage. The next 16 days are looking pretty flat for the most part. We’ve got a big gap coming up with no real surf to speak of.
Looking at the whole picture, we’re starting off with barely a ripple. Monday the 20th through to the morning of Sunday the 27th is a write-off for any proper surfing. The swell is tiny, and the energy is non-existent, with combined swell energy readings as low as 1 to 5. It’s just not happening. You’ll see a few clean windows with offshore or glassy winds, like Tuesday the 28th morning, but with no waves to push you around, it’s a flat spell.
The only real blip of interest is a long way off, on Friday the 31st of July. The morning brings a 8ft swell from the WSW, but with a short period of 7 seconds and onshore wind howling at 19 knots from the ENE, it’s going to be a messy, stormy mess. The combined energy is a big 569, which is a lot of power, but it’s not surfable with that wind. It’d be more interesting for the kite crew than us paddle surfers. The afternoon sees it drop a little to 6ft, but the same onshore wind is a problem. That’s a day for the experts only, and even then, it’s not looking good.
After that, it drops back to flat again. There’s a little 3ft swell on Sunday the 2nd of August, but with a weak 6-second period and a cross-off wind, it’ll be weak and unappealing.
So, the best of a bad bunch? Honestly, there’s no standout here. The water is warm, way above average for this time of year at 68°F (with a 7°F anomaly), but the waves just aren’t cooperating. This is a pretty normal blank run for a sheltered spot like this. We’ll have to wait for the next forecast to see if things change.
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.
