The Lowdown

Alright folks, Rusty here. We’ve got a stretch ahead for St Agnes that’s going to test your patience. For the first ten days or so, it’s looking like a real struggle. The swell is tiny and the wind is mostly messy, so you’re better off saving your energy. There’s a big gap of flat, poor conditions from now until July 24th. Don’t get too excited about the middle of the month either – a little bump of weak, short-period windswell on the 17th only reaches about 3ft, but it’s coming from the NNW with a period of just 6 seconds, and the wind is all over the place. It’s not worth a paddle.

The real standout, the only one worth circling on the calendar, is the morning of Friday, July 24th. This is your window. The water temp is sitting at 65°, which is much warmer than normal for this time of year – a solid 4° above average, so you can leave the thick wetsuit at home.

St Agnes will see a clean, glassy start with the wind swinging light from the WSW, almost a dead calm. The swell is a solid 4ft from the WNW, with a long period of 12 seconds – that’s proper groundswell energy. The combined energy is a solid 454 (moderate), and with that glassy surface, you’re looking at clean, lined-up waves. It’s not going to be huge, but the quality will be there. Just keep in mind the crowds here can be often, so get there early for a peak.

The other day to watch is Sunday, July 26th. It’s a bit more of a gamble. The morning brings a clean 6ft swell from the west with a short 7-second period, and light offshores from the SE. That’s a lot of water moving, but the short period means it’ll be a bit lumpy and less organized. The combined energy is strong at 384. It’s a lot of push, but it’s not the same quality as the 24th. Might be a bit too much for beginners, but for the experienced crew, it could be a fun, punchy session before the wind picks up in the afternoon.

The rest of the forecast is a mixed bag of onshore winds and small, choppy surf. The 27th has some size (8ft) but the wind is cross and the conditions are marginal. The 29th sees another pulse of northwest swell at 7ft, but it’s blown out by cross-onshore winds. Honestly, for the second week, it’s a watch-and-wait game. The only real promise is that Friday morning glass-off.

Stay sharp, and don’t burn your fuel on the flat days.

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.
