The Lowdown
Right then, let’s have a look at what’s on offer here in the St Agnes area. I’m not gonna lie to you, it’s a bit of a frustrating run for the first couple of weeks. There’s swell about, but the wind’s just been a menace, and the forecast is calling it “poor surf conditions” for a solid stretch. We’re looking at a 14-day gap before we get anything that’s even worth a second look, so patience is the name of the game.
The first real chance of a surf comes on Thursday, 24th September, and even then it’s a marginal call. The morning shows some hope with a 6ft swell from the WNW, but the period is a short 7 seconds, so it’ll be a bit lumpy and weak. The wind is light and cross-shore, which is something, but it’s not a paddle-out you’d get excited about. The combined energy is moderate at 333.
Then, on Friday, 25th September, we finally get a bit of a standout. The morning session is the pick of the entire forecast. The swell is 7ft from the W, with a period of 8 seconds. The wind is a gentle breeze from the S, giving us a clean cross-off. The water temp is a touch warmer than normal at 65°. The combined energy is strong at 549. This is the one to aim for. It’s a solid, punchy wave that should be decently clean. The afternoon drops off a bit, but if you’re keen, the morning is the call.
Truth be told, for the first two weeks, it’s a blank run. The wind is either too strong or in the wrong direction, and the swell just isn’t lining up. It’s a tough stretch, but it doesn’t stay poor forever, and forecasts can change. For now, circle that Friday the 25th.

Information about the St Agnes Surf forecast
The above surf forecast table for St Agnes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at St Agnes can be found by selecting the local surf guide option on the grey menu. Our St Agnes 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 (St Agnes) 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 St Agnes 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.
