The Lowdown

Alright folks, Rusty here. Let’s have a look at what St Agnes has got cooking for us over the next couple of weeks.

Well, I gotta be straight with you – it’s a tough start. The first week and a half is pretty much a write-off for any decent waves. We’re looking at a long, dry spell from the 15th right through until the 28th of July where the surf is just flat or gutless. The swell is tiny, mostly around 1ft to 3ft, and the periods are short and weak. The wind is all over the shop, mostly cross or cross-onshore, which just chops things up. It’s a real bummer, but it happens. The combined swell energy is well below 100 for most of that run, just a sad little murmur.

You’ll be waiting until the very end of the forecast for any glimmer of hope. The standout window, and the only one worth getting excited about, is the morning of the 29th of July. The swell finally fills in, with a clean 7ft out of the west, and a period of 9 seconds bringing some shape. The wind is light from the north, making for a light cross-onshore with only small wind ripples. The combined energy jumps right up to a strong 688, which is a solid number. That’s the real deal for the crew who can handle it. At 7ft, this is strictly for the experienced surfers; beginners should stay on the beach. The water temp is sitting at 63°, which is a touch warmer than average for this time of year – a nice little bonus.

The 30th of July still has some size, with 5ft on the Thursday morning, but the wind is onshore and the energy drops to 314. It’s a step down, but still a lot better than the flat spell. The morning of the 30th is the backup option, but the 29th is the clear winner.

So, to sum it up: the first 13 days are a total loss. Don’t bother checking the cam. The only real shot you’ve got is the 29th of July. Wait for that window, and you’ll be glad you did.

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.
