The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for the Swanage area over the next couple of weeks.
Well, I gotta be straight with you, this is a tough one. The first half of the outlook is a bit of a letdown, and honestly, it's a long stretch before we get anything that might be worth a paddle. For the first week or so, it's a flat spell. The only proper swell of note comes in on Friday, 4th September, with a morning pulse of 7ft from the WSW, but it's packing a period of just 7 seconds, and it's getting smashed by a stiff 30 km/h westerly wind. The combined energy (373) is moderate, but the conditions are just poor. That afternoon, the swell drops to 4ft and the energy plummets. After that, it's a whole lot of nothing for days. The data shows a gap from the 8th to the 13th where the swell is practically non-existent, with combined energy sometimes dropping to zero. There are a few tiny pulses here and there, but nothing that'll get you out of bed.
The most promising window we see is later in the period. The standout option, and really the only one that catches my eye, is the morning of Monday, 7th September. That's a full week out, so keep an eye on the charts. We get a 2ft swell from the SW, but the real story is the period – a very long 15 seconds. That's proper groundswell energy. Now, for a sheltered spot like Swanage, that long period is a double-edged sword, but it's the best we've got. The combined energy is moderate (106), and the kicker is a clean offshore wind from the W at 25 km/h. The morning will be clean. The afternoon sees the swell picking up to 4ft from the WSW with a 13-second period, which is still good, but the wind picks up to a fresh 30 km/h cross-offshore. The energy jumps to 581 (moderate), but the wind might make it a bit tricky.
Later in the second week, we get a glimmer on Thursday, 10th September, with a 5ft swell from the SW in the afternoon, but again, the period is short at 6 seconds and the wind is a fresh 30 km/h cross-offshore. The energy is moderate (223), but it's likely to be a bit messy.
Saturday, 12th September morning might be worth a look for a tiny wave session. It's a 1.0ft swell from the WSW with a 7-second period, but the wind is a light 10 km/h offshore from the W. The combined energy is just 17, so it's weak, but it'll be clean. For absolute beginners, any swell over 1.5m (5ft) is too much, so that Monday morning 7ft is out of your league. The few small pulses around the 2ft mark are more your speed, but they're rare.
The water temperature is a standout for that first Friday. At 68°F, it's a massive 6°F above average for this time of year. That's very unusual, trust me. You'll be in for a warm one.
So, to sum it up: the 7th of September morning is the best bet. It's not perfect, but it's the only real quality window with decent energy and clean conditions. The rest is a waiting game.
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.
