The Lowdown
G’day, this is Rusty. We’re looking at a pretty quiet run for the next couple of weeks at Fonte da Telha. The water’s sitting at 71°F, which is about a degree and a half warmer than usual for this time of year – nothing wild, but nice if you’re in a spring suit.
The first week is a bit of a write-off, honestly. Up until Saturday the 16th, swell is small and onshore or cross-shore winds are chopping everything up. Tuesday the 11th and Wednesday the 12th see tiny waves around 2 ft to 3 ft with light cross-shore winds, but the energy is weak (34 to 145) and the wave comment is poor – not worth paddling out for. The real gap continues through Thursday, Friday, and into Saturday morning, with swell bumping up to 5 ft on the 15th but still messy.
Then, on Sunday the 16th morning, we finally get a window. The wind goes glassy – calm, 0 mph – and there’s 5 ft of NW swell with a period of 9 seconds. The combined energy is moderate at 403. It’s not huge, but it’ll be clean and fun for a beginner-friendly session. The break is fairly consistent, and with that glassy wind, it’s your best bet in the whole outlook. The swell direction is slightly off the optimum WSW, but it’s the only morning that’s truly clean.
After that, Monday the 17th morning also looks tidy with offshore E wind at 6 mph and 4 ft of NW swell – clean, surfable, but smaller. The rest of the week is mainly cross-shore or onshore slop, with a few marginal mornings on the 20th and 21st where swell reaches 5 ft to 6 ft, but the wind is onshore or cross-shore, so it’s messy.
Into the second week, the outlook stays pretty average. There’s a slight hope on Monday the 24th morning with light NNE cross-offshore wind and 5 ft of NW swell, energy at 321, and clean conditions – but again, it’s a one-off before the afternoon chop. The 25th and 26th mornings have marginal conditions with moderate swell (5 ft to 6 ft) and cross-offshore or light cross winds, but nothing that’s a standout.
Overall, if you’re keen, Sunday the 16th morning is your best chance – glassy, clean, and a bit of size. The rest of the period is mostly waiting for a better run.
Rusty.
