The Lowdown
G'day, Rusty here. Look, I’m gonna be straight with you – this stretch of coast is in a bit of a flat spell for the foreseeable. We’ve got a 16-day window, and I’m not seeing anything to get excited about. There are no standout surf options on offer right now. The first couple of days look messy and small, and by the time we hit the end of July and early August, the swell just fades away. We’re looking at a few tiny, weak pulses with no decent quality, so if you’re just hanging out for a paddle, it’s going to be a long wait. The models can change, so keep an eye out, but for now, it’s a quiet time.
Let’s run through the first few days. Saturday the 25th has some hope with a 4 ft WNW swell, but the period is a short 5 seconds and the wind is a strong 30 km/h cross-on from the WNW. That’s lumpy, messy, and the combined swell energy is weak (78). The water is a touch warmer than normal at 65°, but that’s the only highlight. Sunday the 26th sees bigger swell – 7 ft – but it’s onshore with 35 km/h NW winds, so the surf is poor and choppy. The energy picks up to moderate (492), but the conditions are a write-off. Monday the 27th is still cross-on, with smaller 4 ft swell and a bit of period (7 seconds), but the energy drops to 220 and it’s still choppy.
The only flicker of something comes on Tuesday morning the 28th. We’ve got a tiny 3 ft WNW swell, but the wind goes glassy with a 5 km/h SSE breeze. The period is a weak 9 seconds, and the energy is only 113, but it’s glassy. The break is fairly consistent, but expect it to be tiny and weak. It’s surfable, but only just. That’s the best we get in the first week, and it’s nothing to write home about.
From there, the swell drops off a cliff. Wednesday the 29th and Thursday the 30th have small, onshore junk. By August 1st, we get a small push of 4 ft to 5 ft WSW swell, with a period of 7 seconds and cross-off winds from the SW – that’s clean at least. But the energy is moderate (221) and the size is marginal. Still, it’s a clean option for a tiny wave. After that, the second week is a dud. The swell drops to 1.0 ft to 1 ft from the 3rd of August right through to the 8th, with periods that are mostly short. There’s a weak pulse on the 9th of August with 6 ft to 7 ft WNW swell, but the wind is onshore and the period is only 7 seconds – so it’s big, messy, and not for the faint-hearted.
The bottom line: don’t bother for the next two weeks unless you’re desperate for a float. The first week has a few tiny, glassy windows, but nothing worth chasing. The second week is a write-off. This kind of blank run is pretty normal for this area, so don’t stress – it’ll come back. Keep your board waxed and wait.
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.
