The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the St Agnes stretch over the next couple of weeks. I’ll be straight with ya – it’s a bit of a slow burner for the most part, with a few promising flashes that’ll get the heart goin’.
We start off with a little bit of life on Tuesday the 28th. The morning’s serving up some clean, surfable waves with a 3 ft swell from the WNW, period around 9 seconds. The wind is a light cross-off, so the surface is gonna be tidy. The water’s a touch warmer than normal for this time of year, sittin’ at 65°, which is a nice bonus. The combined energy is moderate at 116, so it’s not a world-beater, but it’s a fun little session. The afternoon cleans up even more with a glassy surface and the same 3 ft of swell, perfect for a longboard or a fish.
Now, we hit a dry spell. From Wednesday the 29th all the way through to Sunday the 2nd of August, the conditions just aren’t there. The swell drops off, winds get messy, and the quality is poor. The best we see in that stretch is a glassy Sunday afternoon on the 2nd with a tiny 2 ft wave, but it’s just not enough to get excited about.
Monday the 3rd of August shows a bit of potential. The morning has clean 3 ft waves from the WSW with a moderate cross-off breeze, energy is up to 119. But the real news is the afternoon: the swell jumps to 6 ft from the SW with a strong 461 combined energy. The wind is still cross-off, so it’s clean. That’s a solid push of energy, but it’s getting into the size where beginners might find it a handful. Worth a look for the intermediate crew.
Tuesday the 4th has a morning window with 5 ft of WSW swell, but the wind is cross, making it a bit lumpy. The energy is still strong at 315, but the choppy afternoon winds kill it.
The standout for the whole outlook? I’d have to point you to Monday the 3rd of August afternoon. That 6 ft SW swell, with clean cross-off wind, and a healthy 461 energy rating is the best wave we get in the whole period. It’s the only time the size and conditions really line up. It’s a little on the punchy side for beginners, but for the rest of us, that’s a proper session.
Looking further out, the second week turns into a bit of a mess. We get a huge pulse of energy on the 9th of August – 8 ft on Sunday morning with a massive 2150 energy, but it’s howling onshore with a fresh breeze, making it a lumpy, blown-out mess. That’s kite-surfing territory, not paddling. The rest of the week is a mix of onshore winds and poor conditions, with a small window of clean offshore wind on the 12th, but the swell is too small (2-2 ft) to really do anything with.
So, the takeaway: get on it Monday the 3rd of August afternoon. That’s your best bet. The rest of the run is mostly waiting for the next one.
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.
