The Lowdown
Alright folks, Rusty here with your St Agnes surf outlook. Let’s be honest, for the next week or so, it’s a bit of a quiet stretch with a lot of lumpy, choppy conditions. There are a few windows of cleaner conditions, and then a big, powerful swell shows up way out there on August 7th that’s only for the experienced crew.
Looking at the charts, there’s nothing worth paddling out for from now through the end of July. The wind is mostly onshore or cross-onshore, chopping up the swell. Wind speeds get up around 22 mph on Sunday (the 26th), and that WNW swell at 7ft is just a messy, bumpy 8-second windswell with poor energy (582). Not your friend.
Things get interesting on Tuesday morning, July 28th. It’s not big – only 3ft from the WNW at 9 seconds – but the wind will be light offshore from the south at 3 mph, and the wave energy is moderate (113). That’s a clean window. By Tuesday afternoon it goes glassy, with just 2ft on offer. If you’re desperate for a slide on a log, that’s your shot. Wednesday morning the 29th stays clean with a gentle offshore, but the swell is tiny at 2ft.
We hit a dry patch again from Thursday the 30th through Saturday the 1st of August. Then, hold on. On Sunday morning, August 2nd, we get a glassy start with a glassy SW wind at 3 mph. The swell climbs to a clean 5ft from the WSW with a 9-second period and moderate energy (315). That’s the best of the first week and a half – good conditions for an intermediate session.
Monday the 3rd stays clean in the morning with a cross-offshore breeze and 5ft swell, but the wind builds during the day.
Now, here’s the standout. Mark your calendar for Friday, August 7th. The swell absolutely hammers in at 12ft from the west with a 10-second period. The combined wave energy is massive (2662 and 2162). The catch? The forecast says it’s simply too big for this break. This is expert-only territory. The morning has a cross-shore wind, and the afternoon shows a cross-offshore breeze, but the size is intimidating. For the rest of us, this setup looks more interesting for kite surfing than paddle surfing.
Beyond that, the surf drops off quickly over the weekend and into the second week, with messy onshore winds returning.
So, bottom line: the best wave to chase is the clean, glassy Sunday morning on August 2nd. After that, if you’re a serious charger, the Friday the 7th offers a massive, powerful swell, but it’s one for the brave only.
Rusty, signing off.

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.
