St Agnes Surf Forecast and Surf Report

Alright mate, Rusty here. Let's have a look at what St Agnes has on offer over the next couple of weeks.

Straight up, it's a grim start. We're looking at a long stretch of pretty ordinary conditions. The first real chance for a wave comes on Wednesday morning, 26 August, but with swell only 2ft from the west and a short 8-second period, it's small and weak (combined energy of 69). The wind is light offshore though, so it'll be clean, but you'll be scratching around for much.

The next few days are a write-off. Thursday through to the end of August are all plagued by poor surf conditions – moderate to fresh cross-offshore winds, messy swell, and the wave size stays small. Saturday 29 August gets a bit of size – 8ft to 10ft – but with a strong breeze and a cross-shore wind, it'll be a messy, choppy mess. The energy jumps up (589 on Saturday morning, 1615 on Saturday afternoon) but it's all for nothing with that wind.

Sunday 30 August is still marginal, with a fresh breeze. The wind swings a bit more offshore on the Sunday morning, but the swell is still on the messy side. Monday and Tuesday of the first week of September are no better – cross-shore and onshore winds, lumpy conditions.

Now, we do get a glimmer. Thursday morning, 4 September, looks like our first real standout. We've got glassy conditions, a calm wind, and a clean 5ft west swell with a 10-second period (combined energy of 478). That's a decent groundswell, and with zero wind, the waves will be clean and well-shaped. It's a good option for intermediates, but it's not huge. The water temperature is about average for this time of year, nothing unusual.

After that, it's back to a bit of a lull, with small, weak swells and onshore winds through the weekend of 5-6 September. Then, hold onto your hats. Monday morning, 7 September, we get a big one. An 12ft west swell, 10-second period, with a clean offshore wind. The combined energy is a massive 2318. This is a serious swell, but the file notes it's predicted to be too big for this break. This is only for experts, and even then, the size could make it a handful. It's a promising but less certain call from here.

The rest of the week after that drops back down to small, poor conditions.

So, the best on offer is definitely Thursday morning, 4 September at St Agnes for clean, glassy, intermediate waves. Then, keep an eye on the big Monday 7 September swell, but only if you're an expert and you know the break well. The rest of the period is a long wait for anything decent.

Rusty.
