The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Well, I’ve got to be straight with you – this is a tough one. We’re looking at a long, dry spell with hardly any surf worth paddling out for. The entire 16-day window is a bit of a bust, with the first real suggestion of anything surfable coming right at the very end. For the most part, we’re stuck with tiny, weak, and often choppy conditions.
The water is sitting at 66° which is a touch warmer than you’d normally expect for this time of year, but that’s about the only positive.
Let’s start with the first few days. Monday the 27th is a write-off, with a messy 4ft cross-onshore and a combined energy of only 230 – weak. It just gets smaller and choppier through the week. Tuesday the 28th morning offers a brief moment of clean conditions with a light cross-offshore wind, but the swell is a tiny 3ft. It’s surfable, but only just.
The rest of the week and into the beginning of August is filled with poor surf conditions. Winds are onshore or cross-onshore, swells are tiny and short-period (4-6 seconds), and the combined energy is often below 100. There’s a patch of clean conditions on the 3rd and 4th of August, but with waves barely reaching 3ft, it’s hard to get excited. The wind goes glassy on the morning of the 5th, but the swell is a pathetic 1.0ft.
Then things get interesting, but not in a good way for a paddle surfer. From the 7th of August onwards, the swell really starts to build. By the 8th, we’re seeing 7ft swell from the WNW with a moderate cross-onshore wind. The combined energy jumps to 535 (moderate), and it stays big and messy through the 9th. Honestly, with that much size, poor quality, and strong onshore winds, this setup at St Agnes looks far more interesting for a kite surfer than a traditional paddle surfer.
The only glimmer of hope comes on the very last day, Tuesday the 11th of August. The morning session is glassy, with a 4ft swell from the WNW. The energy is moderate at 104, and the clean conditions make it the one standout of the entire forecast. It’s not big, but it’s the best we’ve got.
So, to sum it up: a lot of small, messy, or blown-out days, a big, windy, messy period in the middle, and one glassy morning at the very end of the run. Keep an eye on the 11th, but don't hold your breath for the rest.
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.
