The Lowdown
G'day, Rusty here. Look, I've got to be straight with you – the next couple of weeks are looking pretty average for St Agnes. There's a big gap of nothing special at the start before we finally get a sniff of something decent right at the end of the run.
The whole period kicks off with a real case of the doldrums. From Friday the 24th right through to the morning of Tuesday the 5th of August, it’s a grim run of poor surf and funky winds. We’re talking about a solid ten days of barely a ripple worth paddling for. The swell is consistently tiny, with heights mostly under 3 ft, and the wind is almost always onshore or cross-onshore, putting a chop on everything. The combined wave energy is weak, rarely breaking triple figures, sitting around 39 (weak) to 146 (moderate) at best. You’d be better off checking the cams from the pub.
Then, on the morning of Tuesday the 5th of August, we get a little tease. The wind swings light and cross-off, and the swell bumps up to 4 ft from the north. The wave comment says "surfable but very ordinary," and the energy is a moderate 102. It’s clean, but it’s not going to set the world on fire. Honestly, it’s a "maybe" session if you’re desperate.
The real standout, and the only one worth writing home about, is the morning of Friday the 7th of August. This is the one. Conditions finally line up. The wind goes glassy – dead flat off the northeast – and the swell pushes up to a solid 6 ft from the southwest. The wave comment says "expect good surf conditions." The energy is pumping at 370 (moderate), which is a big jump from the rest of the period. This is a proper window. The swell is a bit chunky with a period of 7 seconds, so it’s not the cleanest groundswell, but with glassy conditions, it’ll be a fun, punchy day at St Agnes. The water temperature is 64°F, which is a touch warmer than normal for this time of year, so that’s a nice bonus.
After that, the weekend of the 8th and 9th of August sees the swell hold up at 7 ft to 8 ft from the west-southwest, but the wind turns onshore again, ruining the potential. The energy is high (801), but it’s a messy, blown-out situation. The early morning on Saturday the 8th is marked as "marginal" due to tide, so it’s one for the experts only if you can find a window.
So, the bottom line: forget the first ten days. The one to circle is Friday morning, 7th of August. That’s your best shot. After that, it’s back to onshore slop.
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.
