Conditions at Ribeira d'Ilhas in July
July: Peak Summer Lull and the Strongest Nortada
July is climatologically the slowest and trickiest month for Ribeira d'Ilhas. Average swell height bottoms out at 1.4m (4.5ft) and the period drops to 8.5s, meaning most of the energy is short-period NW/NNW windswell rather than organised groundswell. The directional spread is extreme: NNW swell accounts for 54.2% of all wave observations and NW another 33.0%. This keeps some shape in the water, but quality is heavily compromised by the persistent NNW wind regime - 59.4% of all wind readings - which is almost never offshore. Only 10% of the month rates as ideal surf conditions, making July a gamble for visitors chasing cleaner waves. The saving grace is the morning, when lighter winds and land breezes can flatten the sea surface for a few hours of fun-sized, grovelly peaks. Air temps reach 20.2°C on average, maxing near 34°C, while water stays pleasant at 17.4°C. Rain is minimal at 0.15mm/day; keep expectations small and chase the dawn windows.
