The Lowdown
Right. Lookin’ at the charts for St Agnes, and I gotta be straight with you – it’s a tough stretch ahead. There’s a real flat spell to start, and the first few days are just not worth paddling out for. We’re looking at a gap of nearly a week before anything even remotely interesting shows up.
The water temperature is sitting at 64°F which is a touch warmer than normal for this time of year, so at least you won’t need the thickest wetsuit.
From Thursday the 23rd through to about Wednesday the 29th, it’s a write-off. Tiny swell, mostly cross-onshore or onshore wind, and the wave energy is pathetic – we’re talking combined energy values in the double digits, like 60 or 39 or 23. It’s choppy, lumpy, and just plain messy. Don’t bother.
Thursday the 30th and Friday the 31st are still poor, but keep an eye on Friday afternoon. The swell direction swings to the southwest and the height bumps up to 7ft, but the period is a short 8 seconds and the wind is cross-shore. The combined energy jumps to 512 (moderate), but the conditions are still listed as poor. It’s a tease.
Now, here’s the one glimmer. Saturday the 1st of August and Sunday the 2nd of August. This is the only real standout in the whole 16-day window. The swell builds from a solid 8ft to 10ft out of the west and west-southwest, with a period of 10 seconds – that’s proper groundswell energy. The combined energy readings are strong: 1374 on Saturday morning and 1852 on Saturday afternoon. That’s serious power. The wind is cross-offshore, which should keep the faces clean, and the wave comment is “marginal” but the conditions are described as “clean”. This is big, powerful surf for experts only. Anything over 8ft is not for beginners, and this is pushing into that territory. The swell direction is from the west-southwest, which is close to the optimum of WSW for St Agnes, so the setup should be decent. Crowds are likely to be an issue though, as it’s often crowded there.
After that, things drop off again. Sunday afternoon the 2nd sees the swell fading to 5ft with a cross-shore wind, and from Monday the 3rd onwards it’s back to tiny, weak, and mostly blown out. The combined energy values drop back to triple and double digits, like 117 and 88. The last few days of the forecast are just poor.
So, bottom line: the first week is a total washout. Your only real chance is the 1st and 2nd of August, when a solid, clean groundswell rolls in. It’s powerful, so know your limits. If you’re an experienced surfer, that’s your window. The rest of the time, the setup looks more interesting for kite surfing than paddle surfing, given the strong winds and poor surf quality.

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.
