The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for St Agnes. Gotta be honest with you, the next couple of weeks look pretty grim for a proper paddle. We’ve got a long stretch of very ordinary conditions ahead.
Right from the start, Friday the 24th through to Monday the 27th of July is a write-off. It’s all small, weak, and choppy with cross-onshore winds. The swell is tiny, barely 2ft to 3ft, with periods of just 4 to 7 seconds, so there’s no real push. The combined energy is weak, reading between 27 and 60 – just a messy, gutless ocean. Not worth paddling out for.
We get a slight glimmer of hope on the morning of Tuesday the 28th of July. The wind swings light from the south-west, turning cross-offshore, and the conditions clean up. The swell is still small at 2ft from the west-northwest with a period of 9 seconds. The energy is weak (87), so it’s just a knee-high, clean little wave. Might be a fun little session on a longboard for a couple of hours, but it’s nothing to write home about. The crowds are often, so you won’t be alone.
The next real standout, and the only event that’s worth marking on the calendar, is the afternoon of Friday the 31st of July. A big pulse of groundswell rolls in from the west-southwest, showing 6ft with a long 11-second period. The combined energy jumps to 846 – moderate wave energy. Now, the wind is a gentle cross-onshore, which will put a bit of texture on the face, but the swell has real power. The west-southwest direction is spot on for St Agnes. This is the best on offer across the whole period. It’s not perfect, but it’s the closest we’ll get to a proper wave.
Then we get a bit of a wildcard on Sunday the 2nd of August. The swell has blown up huge, 10ft to 12ft from the west with an 11-second period. The combined energy is massive at 2197 to 2501 – very strong wave energy. The wind is moderate cross-onshore. Look, this is a heavy, powerful, jumbly ocean. The forecast notes the swell is too big for this break. This is big, gnarly, and messy. If you’re a seasoned expert and you’ve got a big board, maybe, but for 99% of us, this is a day to watch from the cliff. Even then, it’s rough and choppy. The rest of the first week of August is just poor, messy, or too small, with cross-onshore winds ruining the shape.
To sum it up: the standout is the afternoon of Friday the 31st of July – that’s your best bet for a decent, powerful wave. The Tuesday morning of the 28th of July is a clean, small option for a log. The big swell on Sunday the 2nd of August is for experts only in tricky conditions. Otherwise, it’s a long, flat, choppy run. The water temperature is about average for this time of year.

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.
