Lisbon in July The driest stretch of the year. The centre is hot, while beaches toward Cascais and Caparica feel cooler with the sea breeze. Stone streets heat up, so midday walking is hard.
It was a hot month: 28°C by day and 18°C after dark. It stayed mostly dry, with 1 rain day on average. July was bone dry in 11 of 20 years, yet 2016 brought 2 rain days.
Long days, up to 14.8 hours of light, left room for a late stroll after dinner. About 6 days a month still climbed past 30°C, the ones where you looked for shade.
