The Lowdown
Alright, Rusty here. Let's be straight with you: the next two weeks around Swanage are about as flat as a Monday morning pancake. We’ve got a long stretch of junk ahead.
Swanage is a very sheltered spot and it’s showing its true colours. Over the next week, we’re looking at tiny waves, if any. From Monday the 14th right through to Wednesday the 23rd of September, expect ankle-sloshers and knee-high wobbles at best. Swell energy is practically non-existent, often sitting in the single digits. The water temp is sitting at 67°F, which is a massive 6°F warmer than usual for this time of year – that’s very unusual, making for a warm, soupy bath but not much else.
We do get a bit of a pulse around Thursday the 24th, with some chest-high easterly windswell moving in. Swell height picks up to 5 ft from the east, with a short, junky period of 6 seconds. The combined energy jumps to a moderate 132 on the Thursday. But here’s the kicker: the wind is howling onshore from the east at 12-18 mph. That’s going to turn the ocean into a mess of whitecaps. The break is a beach setup, so with that onshore wind and short-period slop, it’s really more of a kite day than a paddle day unless you’re desperate.
After that, it fades back to nothing through the end of the month. If there's one standout, it's a weak mention for the early morning of the 29th, where a tiny 0.7 ft, 13 second groundswell from the WSW bumps the energy to 18, with light offshore wind. It’s clean, but laughably small.
Honestly, for Swanage, this is just how it goes sometimes. There's very little consistent swell. It’s a quiet period with no good surf. Forecasts can change, but right now, the board stays on the rack.

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.
