The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this is a tough one. The next couple of weeks at Swanage are looking pretty bleak for a proper paddle. We’ve got a long run of very small, weak swells and less-than-ideal conditions, so don’t be expecting any barrels.
Looking at the whole 16-day window, it’s a long stretch of nothing special. The first real glimmer of hope doesn’t show up until Monday the 17th of August. We’ve got a gap of over a week from now where the surf is basically non-existent or just not worth getting wet for. The water is sitting at a very warm 69°, which is a lot toastier than normal for this time of year, but that’s about the only highlight.
The first day that offers anything rideable is the morning of Monday the 17th. We’ll see a pulse of 5 ft swell wrapping in from the southwest, giving a moderate wave energy (211). The problem is, it’s a short period at 7 seconds, so it’ll be a bit lumpy and weak. The wind will be offshore from the west, so it’ll be clean, but that’s a fresh breeze, so it’ll be a bit of a battle. Honestly, with that swell size and the wind, it’s going to be pretty ordinary. For a spot that’s very sheltered and rarely breaks, this is about as good as it gets in this window, but it’s nothing to write home about.
The following morning, Tuesday the 18th, sees a bit more energy with 4 ft from the WSW and a better period of 9 seconds (207 energy). This is the pick of the bunch. The wind is cross-off from the southwest, but it’s a strong breeze at 35 km/h, so it’s going to be a real handful. The swell is pushing 5 ft, so it’s a bit much for beginners, and the wind will make it choppy. This is a day for experienced surfers only, and even then, it’s going to be a mission.
The standout, if you can call it that, is probably the Tuesday morning window. The combination of the biggest swell and the cross-off wind gives the best chance of a clean-ish wave, even if it’s a messy one. But remember, this is a rarely breaking spot, so any rideable wave is a bonus.
For the rest of the period, you’re looking at tiny, onshore slop or nothing at all. If you’re a kiter, some of those windy days with 4 ft+ of messy swell might look more interesting than for a paddle surfer.
Stay patient, and keep an eye on the charts. It might not be great now, but it tends not to stay this poor for long.
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.
