The Lowdown
Alright folks, Rusty here. Let’s take a look at what St Agnes has in store for us over the next couple of weeks.
Honestly, we’ve got a long, dry spell to get through first. The forecast is showing a real flat, quiet pattern for the next week and a half. From the 29th of July right through to the 6th of August, the waves are tiny and mostly messy, with light onshore or cross-shore winds. The combined swell energy is weak, barely cracking 70. It’s a real bummer, with things looking poor for a good stretch. There’s just nothing to get excited about for a solid nine days.
Then, things start to get interesting around the 7th of August. The swell finally starts to build, but it’s still a bit rough and raw. The wind is cross-onshore and the wave heights are building, but the surf quality is still not great. The real standout, the one that’s worth circling on the calendar, is the morning of Saturday, the 8th of August. The conditions are set to be glassy with light winds from the ENE. The swell will be a solid 6.9 ft from the west, with moderate energy. It’s not a total monster, but it’s got some push. The water temp is about 64.8°, which is a touch warmer than normal for this time of year. This is the best it’s going to get, with clean, well-shaped waves on the cards. The afternoon will see the wind pick up a little, making it a bit lumpy, but that morning session is the one to chase.
The week after that, from the 9th to the 13th, we’re back into smaller, weaker waves with onshore winds, so the magic won’t last. If you’re a beginner, the 8.2 ft to 9.8 ft swell on the 7th is likely too big, and the 6.9 ft on the 8th will be a bit much for the less experienced. For the experts, that Saturday morning glass-off is where it’s at.

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.
