The Lowdown
Alright folks, Rusty here. Let’s take a look at what St Agnes has brewing for the next couple of weeks. I’m going to level with you – it’s a pretty quiet, tricky stretch, and we’ve got a long run of nothing burger in the middle.
Things start off Monday the 27th with a bit of background swell, but the wind is cross-onshore from the WNW at 15 to 20 km/h, so it’s bumpy and unpleasant. Combined energy is around 230, but it's messy. That’s the theme for a lot of the first few days. On Tuesday the 28th, there’s a little window of hope – the swell drops to about 3ft from the WNW with a 9-second period. The wind goes cross-offshore in the morning, then goes dead glass in the afternoon. Combined energy is weak at 113 and 88 (both play), but for a tiny wave, that afternoon session will be as clean as it gets. That’s the only real glimpse of good conditions in the first week.
From Wednesday the 29th through to Sunday the 2nd of August, it’s a true doldrums. Tiny swell – down to 1ft to 2ft – with short periods of 5 to 8 seconds, and onshore winds. Combined energy is mostly under 100. It’s flat and blown out.
The second week stays tough. Monday the 3rd of August brings a little more life: a knee-high, long-period groundswell from the west at 1ft to 2ft with a period of 9-10 seconds. The wind turns cross-offshore from the east at 10-15 km/h, so it’s clean, but combined energy is still below 100. It’s tiny. After that, the swell builds but the wind fights it. By Thursday the 6th of August, we get a pulse of 5ft to 6ft from the SW, but the period is a short 7 seconds and the wind is cross-shore at 20 km/h. Combined energy reaches 237 and 308, but it’s a chop-fest. Not for paddling.
The only real standout window is Tuesday afternoon on the 28th of July. The swell is a tiny 2ft from the WNW with a 9-second period, but the wind goes glassy – dead calm at 3-5 km/h from the WNW. Combined energy is only 88, but for clean, glassy conditions in the summer, you can’t beat it. It’s small but perfect for a longboard.
Other than that, this is a pretty barren forecast. The swell is either too small or too short-period, and the wind won’t cooperate. It’s a good time to wax your board and wait.
Stay patient, Rusty.

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.
