Alright, crew, Rusty here. We’re looking at a long stretch ahead at St Agnes, and I’ll level with you – it’s mostly a bust for the next couple of weeks. The energy just isn’t there. We’ve got a big ol’ gap of flatness before we even get a sniff of surf.

From right now (July 12th) all the way to the morning of Sunday, July 27th, it’s slim pickings. Day in, day out of tiny, weak waves. Swells are mostly 1ft to 2ft, with combined energy readings barely getting past 100 – mostly stuck in that weak 14 to 65 zone. The wind is often screaming out of the east at 18 mph, which would usually be cross-off here, but there’s no swell to push. A couple of mornings do look glassy or have light airs, like Tuesday July 21st with a glassy start, but the swell is a measly 1ft. It’s a tough watch.

Here’s the one ray of light – it’s way out there, so don’t book time off work yet, but keep the morning of Monday, July 27th in the back of your mind. The models are finally showing something. We’re looking at a 6ft swell rolling in from the west, with the combined energy jumping to a moderate 663. The period is around 9 seconds, and the wind is a light northwesterly at 6 mph, keeping the surface clean with just small ripples. The report calls it “marginal,” but it’s the biggest pulse we’ve seen in this whole 16-day window and it’s our only real shot. St Agnes might actually have some proper lines for the first time in forever. The water temp is about average for the time of year, but after this flat spell, you’ll be stoked just to paddle out.

So, the only one to circle is Monday morning, July 27th. It’s a promising call but take it with a grain of salt – forecasts can shift. Everything before that? Honestly, save your gas. That’s the word from your pal 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.

St Agnes is 13 km (8 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
