The Lowdown

Right, folks. Rusty here. Let’s have a look at what’s going on for St Agnes. The good news is, there’s surf in the long-range picture, but the bad news is we’ve got a solid run of dud days to get through first.

From now until around the 25th of July, it’s pretty grim. We’re staring at nearly a week of flat, messy, or onshore slop. Swells are tiny, under 1ft, or if there’s a little bump, it’s coming straight onshore with a short period windswell that’s just choppy and lumpy. The combined energy is weak, barely registering above 100 (18 to 96). Not worth paddling out for.

The first real glimpse of something comes on the 25th, but it’s still a write-off. Saturday morning has a 4ft W/NW windswell with a fresh cross-onshore, and the afternoon picks up a bit to 4ft, but the wind is still chopping it up. The energy is moderate (117), but the quality is poor.

Now, Sunday the 26th of July is the one that gets the heart beating a little faster. We’ve got a 7ft W swell rolling in. The combined energy jumps to 493 (moderate-strong). The problem? It’s a clean onshore wind from the NNW at 15-18 mph, which is going to blow it out. That’s a lot of water moving, but it’ll be a washing machine. This is expert territory at that size, but the wind is just cruel. The break is a beach-and-reef setup, so with that wind and size, it might actually be more interesting for kite surfing than paddle surfing.

The pattern stays messy for the next week. Swells hang around 3ft to 5ft, but the wind is constantly cross-on or onshore. The energy dips and rises (125 to 261), but the surf quality is consistently poor. There’s a slight improvement on the 31st of July, with a 4ft W swell and a light cross-on breeze, but it’s still not clean.

The standout window, if you can call it that, looks to be the 1st and 2nd of August. The swells are a consistent 4ft to 5ft from the W. The combined energy is moderate (112 to 150). The wind on the 2nd of August morning is a light cross-shore from the WSW, which is the best we’ll see. It’s gentle cross-shore with slight cross-chop – not perfect, but ridable. The 3rd of August morning has a fresh cross-offshore wind from the WSW (18 mph) and a 4ft W swell, which could actually clean up the faces, but the energy is moderate (188). That’s probably the pick of the bunch.

So, overall, there’s nothing firing. The best is a few days of average conditions with a moderate, cross-shore wind. The crowd factor? St Agnes is “often” crowded, so don’t expect it to be empty. The water temp is about average for the time of year. Not a classic Cornish summer, that’s for sure.

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.
