St Agnes Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on offer for St Agnes.

The next couple of weeks are looking pretty quiet overall. The swell energy is weak for most of this first week, and the wind is going to be a problem. We’ve got a long stretch ahead with not much to get excited about.

Sunday, August 2nd – We’re starting off with very small, weak swell. The water temp is sitting at 65°, a touch warmer than usual for this time of year. The combined energy is only 39, so it’s pretty weak. While it’s clean, the waves are just too small and the swell direction is not ideal. It’s a pass.

Monday, August 3rd – A bit more life. We’ve got a 0.9m (3ft) WSW swell with a moderate energy reading of 106. The wind is light and cross-offshore, so the surf will be clean. It’s surfable, but very ordinary. Not a standout.

Tuesday, August 4th – The swell picks up to 1-1.5m (5-5ft), but the period is short (7 seconds) and the wind is strong cross-offshore. The combined energy gets up to 208, but the conditions are poor. The wind is just too strong, ruining the shape.

Wednesday, August 5th – The swell is over 2m (7ft) with a strong 494 combined energy, but the wind is fresh and cross-onshore. It’s going to be big, lumpy, and messy. This is more of a kitesurfing setup than a paddle surf one.

Thursday, August 6th – The swell drops back, and the wind is onshore or cross-onshore. Poor conditions.

Friday, August 7th – Very small again, with a weak energy reading of 39. The wind is cross-onshore, so it’s not great.

Saturday, August 8th – The swell builds back to 1.7m (6ft) from the west with a 403 combined energy, but the wind is cross-onshore. It’s marginal at best.

Sunday, August 9th to Monday, August 10th – The surf drops off sharply. Very small, weak energy, and the wind is still cross-onshore. Not much happening.

Tuesday, August 11th to Wednesday, August 12th – The swell is almost non-existent. Energy values are in the single digits. A complete flat spell.

Thursday, August 13th – A little bump of 0.8m (3ft) WSW swell appears, but it’s onshore wind and the energy is still low at 121. Poor conditions.

Friday, August 14th – Now we’re talking a bit. The swell jumps to 1.8m (6ft) from the WSW, with a combined energy of 448. The wind is light and cross-onshore in the morning, offshore in the afternoon. This is where the best of the outlook sits. The morning, with the light cross-onshore breeze, might give you a cleanish window. The swell is a solid size for an intermediate, but it’s a short period (8 seconds) so it won’t be the most powerful.

Saturday, August 15th – Another 1.7m-1.6m (6-5ft) WSW swell, with the wind light and cross-shore in the morning. The energy is 452. This could be a decent session but the wind shifts stronger in the afternoon.

Sunday, August 16th – The biggest swell of the outlook – 2-2.3m (7-8ft) from the west, with a combined energy of 773. But the wind is strong and cross-onshore, making it messy and big. This is for the experts only, and even then, the conditions are poor.

Monday, August 17th – The swell stays big (2-2.3m / 6-8ft) but the wind doesn’t let up. It’s a disappointing end to the outlook.

The standout in this whole period is Friday, August 14th morning. The 1.8m (6ft) WSW swell has decent energy (448), the wind is light, and combined with the fairly consistent nature of St Agnes, it’s your best bet for a clean, surfable wave. The swell direction is close to the optimum WSW, so the shape should be okay. Just be aware the period is short, so it’ll be a bit crumbly. The crowds are "often" here, so don’t expect to have it to yourself.

Other than that, it’s a long stretch of poor to flat conditions. Keep an eye on the long-range for Saturday, August 15th morning, but everything else is a write-off.

Rusty.
