St Agnes Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’m looking at the surf forecast for St Agnes.

First up, we’ve got a bit of a slow start, but there’s a window of cleaner surf early on. Saturday the 5th of September is the first real chance to get wet. The morning’s a bit average with a 5ft swell from the WNW, period around 12 seconds, and a light cross-on breeze putting some ripples on the face. The combined energy is moderate (665). Not terrible, but the tide and that wind state are making it a tough call. The afternoon cleans up nicely though – the wind swings to a light cross-off, swell drops to 4ft with a solid 11-second period, and the energy is still decent (432). The report says “good surf conditions,” and I’d say for a Saturday arvo, that’s your best bet early on. It’s a fairly consistent break, so expect a few others out there, especially with the crowds described as “often.”

Sunday morning the 6th has a tiny 2ft swell and a fresh offshore breeze, but with only 97 energy, it’s honestly barely breaking. By Sunday afternoon, it’s even smaller.

Then we get a pulse. Monday the 7th of September brings a decent swell – 8ft from the W with a 13-second period, pushing energy right up to 1942. That’s strong wave energy. The problem is the wind: moderate cross-shore and a cross-chop. It’s not clean, and the report flags it as marginal. This is a wave that’s more for experienced surfers; at 8ft, it’s already pushing into the “too big for beginners” territory. The quality is questionable, so don’t expect a perfect session.

The rest of the first week and into the second week is a write-off. From Tuesday the 8th of September right through to Sunday the 20th of September, every single entry is marked as “poor surf conditions.” The swell drops off, the wind is messy, and the energy levels are low – mostly under 500. There’s a few days with a bit of size, like Wednesday the 9th with 5ft and Thursday the 10th with 7ft, but the wind is cross or cross-on and the period is short, creating a lumpy, choppy mess. It’s not going to be worth the paddle. Honestly, for a stretch of nearly two weeks, there’s just nothing on offer.

So, to wrap it up: your best bet is the afternoon of Saturday the 5th of September. It’s not a world-beater, but it’s the cleanest, most rideable wave in the whole forecast. The rest of the 16-day window? A long, flat, and windy gap. The water temperature is about average for the time of year, so no surprises there.
