The Lowdown
Alright, Rusty here, and I’m looking at the situation for Fonte da Telha. Let’s be honest, it’s a rough outlook for the next stretch. The first week and a half is mostly a bust, with only a single, brief window that’s worth paddling out for, and it’s a long way off.
Right now, and through the end of July into early August, it’s a real grind. The swell is tiny, mostly under 3 feet, with weak energy readings (mostly under 100, occasionally hitting the low hundreds). The wind is the killer—stuck out of the NW, blowing cross or cross-onshore, keeping the surface lumpy and chopped up. The water is 71°, which is a touch warmer than normal for this time of year, so the water feels good, but that’s about all you’ve got going for you. You’re looking at roughly 10 days of poor conditions with no real standout.
The one bright spot is Wednesday morning, July 29th. That’s the day. The swell jumps up to a solid 7 feet from the NW, with a 9-second period, and the energy reading is a massive 1164—that’s some serious power. The wind goes light and cross-offshore from the N, giving you clean, lined-up waves. The report says it’s excellent for experienced surfers, and that’s right. At over 7 feet, this is for the experts. The waves will have some real grunt. The catch? It’s only for the morning. By the afternoon, the wind shifts and the quality is gone. The rest of that week and into the weekend, the swell backs down and the wind gets messy again.
So, if you can make that Wednesday morning session, you’ll get the best of the 16 days. Otherwise, it’s a waiting game. Keep an eye on the forecasts.
Rusty.
