Table - best surf conditions forecast for St Agnes over the next 16 days.
Alright, folks, Rusty here. Let's chew the fat on this forecast for St Agnes.
Well, I gotta be straight with you – it's a bit of a rough stretch ahead. The next 16 days are looking pretty flat and messy for the most part. We've got a real gap here with no surf worth talking about for the first few days, and honestly, the pattern doesn't really set up for anything classic. There's a couple of pulses of energy, but the wind's just not playing ball. It's a bit of a lean spell, but that's how it goes sometimes.
The only real window of hope is a bit of a push around the 18th and 19th of July. The combined energy jumps up noticeably to 415 (strong) on the Saturday morning, with a swell of 5 ft from the W. That's a decent size, a bit too much for beginners, but the real problem is the wind. It's been blowing from the NW onshore, so those waves are gonna be a mess. By Sunday afternoon, it's a fresh cross-onshore with lumpy conditions, and the energy is still high at 214 (moderate). The period is short, around 7-8 seconds, so it's gonna be a bit of a crumbly, wind-affected mess. It's a shame, because there's some energy there, but the quality just isn't there for a good paddle session.
The rest of the period is a write-off. We see a bit of a bump on the 24th with 3 ft from the WNW and a period of 11 seconds, and the energy is moderate at 242. But the wind is cross-shore or cross-onshore, and the forecast says "poor surf conditions." So, it's a tease.
Honestly, there's nothing here that gets me fired up. The water temp is about 62° which is a bit warmer than normal for this time of year, but that's about the only highlight. The sets are gonna be weak, the wind is gonna be in the way, and the quality is just not there. This stretch is looking more like a time to get the kite gear out if the wind picks up, 'cause for a paddle surfer, it's a tough watch.
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.
