The Lowdown
Alright, Rusty here. Let's have a look at the 16-day window for Ribeira D'ilhas. Straight up, it's a pretty grim stretch. There's nothing on offer right now, and it stays that way for a long time. The first few days have tiny, weak, onshore slop it's not even worth describing. We're looking at over a week of this poor quality stuff. The setup is a consistent reef break, but it just doesn't matter when the swell and wind are this bad.
The only real pulse of energy comes through late in the window, but the wind is a mess. From Monday the 27th of July into the first of August, the combined swell energy starts to climb, hitting strong values around 366 and 536 (moderate to strong wave energy), with swell heights around 5 ft to 7 ft. The problem is the wind is a persistent cross-onshore from the north, which is gonna make it choppy and lumpy. That NNE to NW wind is just not giving us a break. The swell direction is mostly NNW, which is okay for the WNW optimum, but not a perfect match. The water is about average for the time of year at 67.5°.
For a beginner reef, the size on the 27th and 28th of July, with 6.5 ft to 7 ft swell, is getting too big for learners, and the quality is poor. Honestly, with the wind set up like this, it looks more interesting for kite surfing than paddle surfing. None of these days are a standout. There's just no good surf on offer here. It's a blank run for the area in this forecast.
