The Lowdown
Alright folks, Rusty here. Let’s take a proper look at what’s coming up for us over the next couple of weeks.
Right off the bat, I’ve got to be straight with you – this is a tough stretch. We’re looking at a long, dry spell with no real surf to get excited about for most of the forecast. The first few days are a total write-off. From Tuesday the 21st all the way through to the end of July, the waves are tiny, the wind is mostly onshore or cross-onshore, and the energy is basically non-existent. It’s one of those frustrating periods where you’re better off doing something else.
We do get a little blip of energy rolling in on Sunday the 26th of July. The swell bumps up to 5ft from the WNW, but the wind is stiff onshore from the NW, and the combined energy hits 228 (moderate). That’s going to be a messy, lumpy mess. Not a standout by any stretch.
The real tease comes right at the very end of the forecast window. On Tuesday the 4th of August, the conditions finally start to look like something we can work with. The wind swings offshore from the SSE, coming in at 16 mph, and the swell is a clean 2ft from the west with a period of 8 seconds. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year. The combined energy is only 40 (weak), but the wind is clean, and that makes all the difference. If you’re desperate for a paddle, this is your best bet, but keep your expectations in check.
Wednesday the 5th of August looks even better. The wind is clean cross-offshore from the WSW at 12 mph, and we’ve got 4ft of west swell with a period of 7 seconds. The energy is moderate at 176. It’s not huge, it’s not long period, but it’s clean and rideable. That’s the best we’ve got on offer.
The standout for the whole forecast? It’s got to be Wednesday the 5th of August at St Agnes. The swell is 4ft from the west, the wind is cross-offshore and clean, and the combined energy is 176 (moderate). It’s a lunch-break special, not a world-class day, but in this dry stretch, it’s the only window that’s truly worth paddling out for.
Hang in there, boys. It’s been a flat spell, but it won’t stay poor forever. Forecasts can change.
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.
