The Lowdown

Right then, let’s have a look at what’s on the cards for St Agnes over the next couple of weeks.

To be honest, the first ten days or so are a bit of a write-off. We’re looking at a long, frustrating gap with hardly any surf worth paddling out for. The water temperature is sitting around average for the time of year, nothing abnormal there, but the swell just isn’t cooperating. The first real glimmer of hope doesn’t show up until Monday morning, the 3rd of August. Even then, it’s small stuff – a 3 ft swell from the WSW with a short period of 8 seconds, and the combined energy is weak (101). The good news is it’s glassy, dead calm, so if you’re desperate for a longboard session and just want to sit out there, it’ll be clean. But the waves are ordinary, and you’ll be sharing the water, crowds are often an issue here.

That Monday morning is the only time the score is even worth a mention. After that, it’s a whole lot of nothing. The wind swings around onshore or cross-shore, and the swell stays small or messy. Tuesday morning the 4th has a bit more size at 4 ft from the SW, but the wind is a stiff 16 mph cross-offshore, which cleans it up but the period is a paltry 6 seconds, giving it no push. The energy is moderate (140), but the surf is still poor.

The next week doesn’t get much better. There’s a bigger pulse on Tuesday the 11th of August – a 5 ft swell from the W with a period of 10 seconds, and the combined energy jumps to 390 (moderate). But the wind is cross-onshore in the afternoon, chopping it up. The morning is a cross-shore breeze, making it marginal at best.

Then, finally, we get a standout. Wednesday morning, the 12th of August, is the one to circle on the calendar. The forecast shows a 5 ft swell from the WSW, with a period of 9 seconds, and the combined energy is a solid 313 (moderate). The wind is light and cross-offshore from the SSW at 6 mph, which will keep the surface clean. It’s the only time in the whole 16-day window that the guidance says “expect good surf conditions.” This is your best bet by a long way for St Agnes. The swell direction is a touch off the optimum, but the conditions are going to be far better than anything else on offer. After that, it’s back to poor, with the wind cranking up and the swell dropping off.

So, a long wait, but that Wednesday morning looks like a proper little window. The rest of the time, it’s a case of checking the cam and hoping the forecasts change.

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.
