The Lowdown
Alright folks, Rusty here. Let's take a look at the St Agnes stretch over the next couple of weeks. Gotta be straight with you, it's a tough run for most of it. The water is sitting at 64°, which is a touch warmer than normal for this time of year.
Right now, we're looking at small, weak swell with moderate onshore winds, so Wednesday is a write-off. Thursday morning, the 23rd, we get a brief window where the wind goes glassy and the swell is 3 ft from the NNW with a period of 6 seconds. It's surfable but very ordinary, a real short-period windswell.
After that, it's a long gap of poor to non-existent conditions. Wind stays onshore or cross-onshore pretty much straight through until Sunday, the 2nd of August. Expect a lot of small, choppy days with very little energy.
The real standout is Sunday, August 2nd. We've got a 7 ft swell from the WSW (combined energy 521 – moderate energy), and the wind is offshore from the SSE, creating clean conditions. The period is only 7 seconds, so it's a short-period windswell, but with offshore wind and that size, it will be fun. Morning is looking best, with afternoon staying clean and a 6 ft swell. This is the one to aim for; the swell direction is offshore and matches the optimum, so it should be good.
Another option worth a look is the Wednesday morning, August 5th. It's a tiny 3 ft from the west with a 10-second period, but the wind is glassy. It'll be clean but small, a classic small-wave longboard day. After that, the wind cranks up onshore again, and we're back to choppy, lumpy surf, so that Sunday, August 2nd, is your real hope in this window.

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.
