The Lowdown
Alright folks, Rusty here. Let's get straight into it for the St Agnes area. I've gotta be honest, looking at the charts for the next couple of weeks, it's a pretty grim run. There's no real surf to get excited about, so don't be in a rush to wax up.
We start off with absolutely nothing. Thursday the 16th and Friday the 17th are flat with tiny, weak 1ft slop. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, but it's not going to make the lack of waves any easier to swallow. Saturday and Sunday the 18th and 19th see a tiny bump from the north, but it's short-period, onshore junk. The wind is howling from the north at 15-19 mph, making a mess of anything that might try to show.
The whole of the following week, from Monday the 20th right through to Saturday the 26th of July, is more of the same. We get a few small pulses, but the winds are persistently onshore or cross-onshore from the north. That groundswell on the 24th and 25th (Friday and Saturday) pushes the wave energy into triple digits, hitting 137 and 158, but it's a short-period, onshore close-out. Look, with those strong winds and choppy conditions at a beach setup, this actually looks more interesting for kite surfing than paddle surfing. There's just nothing clean for us.
We finally catch a break on Sunday the 27th of July. The wind swings around to a light cross-offshore from the southwest, and we get a bit of 2-3ft groundswell from the west. The energy is moderate (109). It's not going to be pumping, but for the first time in the forecast, the surface will be clean. Monday the 28th through the end of the month sees the swell drop back down to tiny, pathetic 1-2ft waves with onshore winds returning. It's a long, quiet spell, and with no consistency in size or wind, this kind of blank run is pretty normal for the area this time of year. We’ll have to wait and see if the forecasts change.
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.
