The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for the next couple of weeks around St Agnes is a tough one for paddle surfers. We’re looking at a long dry spell with very little worthwhile swell energy on the cards.
The whole forecast period kicks off on Thursday, 30th July, and honestly, it’s a grim start. We’ve got a weak 2ft swell from the west with a short, weak period of 8 seconds, and the wind is a messy cross-on. The combined energy is only 54 (weak), so it’s flat and choppy. That same story runs right through Friday, the weekend, and into Monday, 3rd August. The swell bumps up slightly to 3ft on Monday morning, giving a combined energy of 113 (moderate), but it’s coming from the WSW with a cross-on wind, so it’s still a no-go for quality waves.
There’s a gap of a few days where we don’t get anything surfable, but then on Wednesday, 5th August, we finally see a bit of a glimmer. The morning shows glassy conditions with the wind swinging light and variable. The swell is tiny at 3ft from the north, with a short period of 6 seconds. The combined energy is only 79 (weak). It’s surfable, but very ordinary. The water temp is about 65°, which is a touch warmer than normal for this time of year.
After that, it’s back to nothing. From Thursday, 6th August, right through to Friday, 14th August, the swell drops to practically nothing – 0.7ft to 1ft with weak energy readings. The wind is often offshore or cross-off, which would be great for shape, but there’s simply no swell to work with. The combined energy values dip into single digits, so it’s basically flat.
The one time we see a little kick is on Wednesday, 12th August, with a 4ft swell from the northwest. The period is a short 5 seconds, and the wind is onshore, making it a messy, blown-out option. The energy hits 107 (moderate) in the afternoon, but with onshore wind, it’s just not worth paddling out for.
To be honest, for the whole 16-day run, the only session that looks even remotely interesting is that glassy Wednesday, 5th August, but it’s tiny and weak. For experienced surfers, it’s a flat spell. For beginners, even the bigger days are blown out and messy. Given the lack of quality swell and the persistent onshore or cross-on winds on the bigger days, this setup looks more interesting for kite surfing than paddle surfing. The forecasts can always change, but right now, it’s a waiting game.
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.
