The Lowdown
G’day, Rusty here, and I’ve got to be straight with you – the next couple of weeks are shaping up as a real test of patience. We’re looking at a solid run of poor conditions at St Agnes, with no real standout days to get excited about. The swell is around, but the wind and chop keep it from coming together.
The first real sniff of something happens on the morning of Tuesday the 28th. We get a bit of glassy magic with light SW winds, and while the swell is tiny at only 1 ft from the W, it’s clean and surfable. The combined wave energy is a weak 60, so it’s a longboard-only affair, but if you’re desperate for a glide, that’s your window. The water temp is about average for this time of year.
After that, it’s a rough run. The wind swings onshore and ramps up, with a lumpy 7 ft swell from the WNW on Sunday morning the 26th, but it’s trashed by a fresh cross-onshore breeze. The energy is punchy at 469, but the quality is poor – more of a washing machine than a wave face.
Into the first week of August, we get a brief clean spell on Friday the 31st of July morning, with light SSW winds and offshore flow. The swell is still small at 2 ft from the W, and it’s clean, but it’s not going to set the world on fire. There’s a bigger spike on Saturday the 1st of August afternoon, with 7 ft from the SW and 386 energy, but it’s hammered by a moderate cross-onshore, making it messy and only for the committed.
Bottom line: there’s no real standout here. The conditions are mostly poor, and the few cleaner windows are tiny. For a spot like St Agnes, this kind of blank run is not unusual. Keep an eye on the forecasts, because it won’t stay grim forever, but for now, maybe break out the fishing gear.
Stay keen,
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.
