Alright folks, Rusty here. Let’s take a look at what’s on the cards for St Agnes over the next couple of weeks.
Straight up, I gotta be honest with you – the start of this outlook is a tough one to write. We’re looking at a real long dry spell. From Monday the 6th right through to Sunday the 19th of July, it’s pretty much all poor surf conditions. There isn’t a single recommendation I can point you to for a proper session during that whole stretch. The water temp is sitting at a pretty average 60°F for this time of year, nothing out of the ordinary there, but the waves just aren’t cooperating.
We’ve got a few days of small, weak swell in the 2ft range with short periods around 8 to 9 seconds. The winds are mostly cross or cross-onshore, keeping things choppy and messy. The combined energy figures are low, mostly bouncing between 75 and 130 – that’s weak to moderate energy, and it’s just not doing anything for us. It’s a real bummer, but it happens.
Now, after that long quiet period, things start to wake up. Towards the back end of the run, around Saturday the 18th, the swell really starts to build. By Saturday morning, we’ve got 7ft of swell rocking in from the WSW, with a short period of 8 seconds. The combined energy is strong at 606, but the wind is onshore from the NNW at 9 mph, so it’s going to be a bit of a washing machine. That size is getting into expert-only territory, too.
The real standout, the one I’d circle on the calendar, is Monday the 20th and Tuesday the 21st. Monday morning shows a solid 8ft swell from the west, period of 8 seconds, and a whopping combined energy of 798 (strong). The wind is a light, cross-onshore breeze from the NE at 9 mph, so it’ll be a bit bumpy but there’s plenty of power. Tuesday the 21st looks even more promising. The morning session has a cross-offshore wind from the ESE at 19 mph, but the swell holds at 8ft from the west. The energy jumps right up to 1156 (very strong), and the wind description is "clean." That’s the kind of setup that gets the heart pumping. The swell direction is WNW, which is a pretty good match for St Agnes’ exposure to WSW. Keep in mind, at 8ft, this is big, powerful stuff and really only for the experienced crew.
So, the summary is: a long, frustrating wait with nothing on offer until the very end of the period. But if you can hold out for Monday the 20th and especially Tuesday the 21st, there could be some proper, heavy waves to get into.
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.
