The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the stretch ahead.
Right off the bat, I gotta be straight with you – the next few days are looking pretty grim. We’ve got a solid stretch of poor surf and messy conditions that’ll test your patience. The swell is out of sync with the wind, making for a lot of lumpy, chopped-out water. The first real glimmer of hope doesn't pop up until the morning of Friday the 28th.
That morning, Fonte da Telha starts to show some life. The swell builds to a solid 7ft out of the WNW, with a period of 11 seconds, giving it some decent grunt. The combined energy is a solid 1010 (moderate to strong). The big news is the wind – a light cross-shore from the NNW at 6 mph. That’s going to clean things up nicely. It’s not a perfect score, but it’s the best we’ve seen in a while. This is the standout of the whole forecast. The water temp is sitting at 69°, which is pretty much normal for this time of year, so no wetsuit drama. Just keep in mind, this spot can get crowded, and with the conditions looking up, expect some company.
After that, we slide back into a funk. The Saturday morning (29th) has a cleaner look with a cross-offshore breeze, but the swell drops to 5ft. The energy is still there (394) but it's a big step down from Friday. The rest of the forecast stretches out long and flat, with mostly poor surf and small, weak waves. The combined energy numbers drop below 100 on many days, and the periods are short, so you’re looking at a lot of flat, blown-out days. Sunday morning the 6th of September has a tiny pulse of energy (110) with a 3ft swell, but it’s cross-shore and not worth getting excited about.
So, the takeaway: if you’ve got a window, hit Friday morning the 28th of August. That’s the only real session on the cards. The rest of the 16 days is a long, dry spell of waiting. Forecasts can always change, but for now, it’s a quiet outlook.
Rusty.
