The Lowdown

Right then, let’s have a look at what’s on the cards for St Agnes. It’s a bit of a mixed bag over the next couple of weeks, if I’m honest. The water temp here is sitting at 64°, which is a touch warmer than normal for this time of year, so you might get away with a thinner suit.

The first half of the week is a write-off, really. We’ve got a solid 7ft swell from the WSW on Wednesday afternoon, but it’s wrapped in a 30 km/h cross-shore wind, making it lumpy as hell. Not worth paddling out for. That same pattern sticks around through Thursday and Friday with similar-sized swells, but the wind stays onshore or cross-shore, keeping everything choppy and messy. The combined energy on Friday morning hits 688 (moderate), but the cross-onshore breeze ruins any chance of clean waves.

Now, look ahead to Saturday the 5th of September. That’s the one bright spot in the near term. Saturday morning brings a 5ft swell from the WNW, with a lovely 12-second period. The wind drops right off to just 5 km/h from the SW, giving us a clean, cross-offshore condition. The combined energy is 568 (moderate), and for a few hours it’ll be proper fun. That’s the pick of the bunch for the next week. The afternoon will still be surfable with 4ft and a light breeze, but it’s more marginal.

After that, the surf drops right away. Sunday sees tiny 2ft waves, and the wind swings offshore, but there’s just no energy in the water. Monday the 7th looks like a bit of a beast, with a 7ft W swell and a 12-second period, pumping 1283 combined energy (strong). But the wind is a cross-onshore 25 km/h, so it’ll be choppy and hard to enjoy. Too big for beginners, and the wind makes it a challenge for everyone else. That setup might actually be more interesting for kite surfers than paddle surfing.

The rest of the outlook is pretty grim. There’s a gap of several days with no real recommendations. Tuesday the 8th, Wednesday the 9th, Thursday the 10th – all have decent swell heights (6ft to 8ft), but the wind is consistently cross-onshore or onshore, keeping the surface ugly. The combined energy on Thursday the 10th afternoon hits 1747 (very strong), but it’s a messy, lumpy mess.

The second week has very little to offer. By the 12th of September, we’re down to 3ft, and the conditions are just ordinary. It’s a long, quiet run after that, with mostly small, wind-affected waves. The 13th has some 5ft swell with a long 11-second period, but the wind is cross-shore again. The 14th has strong winds up to 40 km/h, so that’s a no-go. The last few days dropping to 2ft are barely worth a mention.

So, if you’re itching for a paddle, get out on Saturday morning the 5th. That’s your best shot. The rest of the window is a waiting game.

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.
