The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Fonte da Telha.
Right now it's pretty grim. We've got a run of poor conditions across the first few days and nothing worth paddling out for until Saturday morning the 12th. Even then, it's still small at 3 ft from the NW, period only 8 seconds, but with glassy conditions, you could get a few grovelly ones. That's the first sniff of anything rideable. The water temp is sitting at 68°, which is just a tad cooler than normal for this time of year, but nothing to write home about.
We then hit a bit of a lull again – Sunday the 13th morning stays tiny (2 ft, NW, 10 second period) with glassy conditions, but the energy is still low (167). Sunday arvo and Monday go messy with cross-onshore winds and weak lumps. Tuesday the 15th is a write-off, and Wednesday the 16th sees a jump in size to 6 ft – 7 ft from the NW, but with a fresh cross-shore wind up to 22 mph and short, junky period (9 seconds), it's just a lumpy mess. Honestly, that looks way more like a kite session than a surf.
Now Thursday the 17th morning is where it starts to get interesting. Swell holds at 6 ft from the NW, 11 second period, with clean conditions and a light cross-offshore breeze from the NNE. The swell energy is strong at 668. This is the first proper standout for experienced surfers – solid, clean waves, but at 6 ft it's getting into the territory that's too much for beginners. Crowds are often here, so expect company.
Friday the 18th morning remains clean again with 4 ft NW swell (10 seconds, energy 296), and a light offshore. Good fun for the intermediate crew.
Saturday the 19th morning is another beauty: glassy conditions, 4 ft NW swell, 10 second period, energy at 269. Another clean session for those who can get out early before the wind swings.
After that, things drop back down into the knee-to-waist high range through to mid-week with only the odd clean window. But check out Friday the 25th morning – that's the real standout of the whole outlook. We've got 4 ft of NW groundswell, with a very long 15 second period, and glassy conditions with a light offshore from the east. Combined energy is 867, which is strong. This is a proper long-period groundswell, so it'll wrap in clean and powerful with nice shaped sets, but at a beach break that long period can make things a bit straight. Still, you'd be mad not to be out there. That one is for the experienced surfers. Saturday the 26th morning is also worth a mention, with 4 ft, 12 second period, offshore wind, and clean – a solid follow-up.
So, if I had to pick the cream of the crop: Thursday 17th morning for the bigger, punchy NW swell, and Friday 25th morning for the longer-period groundswell with glassy conditions. Mark those in the calendar.
Signing off, Rusty.
