The Lowdown
Alright, folks, Rusty here. Let's have a look at the 16-day picture for this stretch of coast, focusing on one familiar spot: St Agnes.
Right off the bat, I gotta be straight with you—it's a grim start. We're looking at a stretch of days where the surf is practically non-existent or just plain ugly. For the first week and a half, it's a washout. From the first of August all the way through to the morning of the 12th, don't expect anything worth paddling out for. There's nothing to get excited about. The winds are messy, and the swell is tiny or blown out. We're talking a solid 11-day gap where you're better off doing something else.
Now, the first real flicker of life shows up on Monday morning, the 12th of August. We see a pulse of swell pushing up to 4ft from the WSW, with a period of 8 seconds and moderate energy in the water (283). The morning offers a light cross-onshore breeze, but the surf is still rated as marginal due to questionable conditions. It’s a glimmer, but not much more.
Then, on the morning of Wednesday, the 13th of August, we get something that might make you take notice. It's not huge, with swell at 4ft from the WSW, but the wind drops right out. We're calling it glassy. That's a major positive. For that one brief window, if you can get out there, the waves should be clean and smooth. The energy is moderate (183), and with the wind like that, it's your best shot in this entire outlook. It's just one session, though, so make it count.
After that morning, the winds pick up again and the quality drops straight back into that cross-onshore chop.
Looking way ahead to the final Sunday and Monday of the outlook, the 16th and 17th, there's a bigger pulse of swell forecast—8ft to 8ft from the WNW. That's getting into serious territory, probably only for the experienced crew. The combined energy is strong (608 and 730). But the conditions are still messy, with cross-onshore and cross-shore winds. That size and wind combo looks more like a kite-surfing setup than a clean paddle session.
Water temp at St Agnes for that first mentionable window sits at 65°, which is a touch warmer than normal for this time of year.
Overall, it's a tough 16 days. The Wednesday the 13th morning glass-off is the one to aim for; everything else is a fight against the wind or a complete flat spell.
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.
