The Lowdown
Alright, let me level with you. I’ve been staring at the charts for Swanage, and honestly, it’s a tough stretch.
Right now, we’ve got a real flat spell on our hands. The first few days will see the water practically glassed over but with no energy to speak of. The swell just isn’t showing up. The numbers are barely budging, with the combined energy sitting at a weak (0-44) for the entire run. By Monday the 16th, we start to see tiny little bumps, but they’re all coming in under 2 ft. The winds are a mixed bag of cross-off and cross-on, but even then, there’s just no power in the water.
Through to the end of September, it’s the same story: small, weak pulses of swell from the WSW and SW. The periods are all over the place, from a snappy 4 seconds to a drawn-out 14 seconds, but it doesn’t matter because the height is just anemic. The wind swings around from the NE and SE, and most of the time it’s onshore or cross-onshore, which is a shame when the break is so rarely breaking anyway. For a spot that’s “very sheltered” to the SW, the optimum direction, the stars just aren’t aligning.
The one thing that’s a bit of a talking point is the water temperature. On the 14th, it was sitting at 67°, which is a whopping 6° above the usual for this time of year. The water is much warmer than normal. It’s a weird feeling to be looking at flat, warm water.
Because there’s no real swell on the cards, there’s nothing to get excited about. If you’re a kite surfer, the moderate to fresh breezes from the NE around the 27th to the 29th might offer a bit of a window, but for paddle surfing, it’s a washout. You’re looking at a long, quiet fortnight. Forecasts can change, but for now, it’s a solid time to wax the board and wait.

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.
