The Lowdown
Alright, Rusty here, let’s have a look at what’s cookin’ for St Agnes over the next couple of weeks.
Honestly, right off the bat, it’s a tough stretch. We’re kicking off with a real flat spell. It’s a bit of a bummer, but don’t chuck the boards in the shed just yet. There’s a sliver of hope tucked away in there.
The first few days, from Saturday the 25th through to Monday the 27th, are pretty much a write-off. We’ve got some small swell around 3 ft to 7 ft, but every single session is ruined by strong onshore or cross-onshore winds. The wind is cranking from the NW and WNW, making it messy and lumpy. The combined energy of all swells directed here peaks at 415 during Sunday the 26th, but with that wind, it’s just a frustrating, blown-out mess. The water’s about average for this time of year, no big anomaly there.
We finally get a little window on Tuesday morning, the 28th of July. It’s still small, with a 2 ft swell from the WNW, but the wind swings around to a light offshore from the SE. It’s clean, but honestly, the waves are weak and ordinary. The swell period is a short 9 seconds, so it’s not packing much punch. The combined energy is only 89, so it’s pretty feeble. You could get a few ankle-snappers, but don’t expect much.
Then we drop back into a flat spell again. From Wednesday the 29th right through to Monday the 3rd of August, it’s all small, weak swell (1.0 ft to 3 ft) and poor conditions. The wind keeps shifting around, but it’s never really favorable. The combined energy levels are all below 100, just weak and lifeless. It’s a proper blank run.
Now, here’s the one that might have you perking up. The only truly interesting pulse comes in the second week. On Wednesday the 5th of August, we see a jump in swell size, with 8 ft to 10 ft from the west. The combined energy of all swells directed here jumps to 1145 and 1372, which is strong. The period is around 9 seconds, so it’s a solid windswell. But, and this is a big but, the wind is howling onshore from the NE and N at 12–16 mph. The conditions are described as "poor". At that size, 8 ft to 10 ft, this is strictly for experts only, and even then, the onshore wind will make it a battle. The setup at St Agnes is a beach, so with that much wind, it’s going to be a choppy, heavy mess. Honestly, it looks more interesting for a kite surfer than a paddle surfer that day.
The rest of the second week, Thursday the 6th through to Sunday the 9th, tails off again. The swell drops back under 7 ft, and the wind stays onshore from the NNW and WNW. The combined energy drops back to the 62–379 range. Nothing special.
So, what’s the verdict? The best on offer is that Tuesday morning, the 28th of July. It’s the only time the wind is offshore, giving us a clean surface. The waves are tiny, but if you’re desperate for a glide, it’s your only shot. The 5th of August has power, but it’s a washing machine for experts only. For the rest of us, it’s a waiting game. The forecast can always change, so keep an eye on it, but right now, this is a tough run for St Agnes.
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.
