Translate Lisbon’s monthly curve into walking and day-trip pacing
At the Lisbon reference point (2001-2025), monthly mean temperature rises from 12.9 °C in January to 19.9 °C in July and 20.6 °C in August, while mean precipitation drops from 2.1-3.1 mm/day in late autumn and winter to 0.1 mm/day in July and August.
Spring (April mean 15.0 °C, 1.8 mm/day; May 17.1 °C, 1.2 mm/day) and early autumn (September 19.9 °C, 1.0 mm/day; October 18.6 °C, 2.6 mm/day) balance comfortable hill-walking temperatures with long daylight hours.
- Summer (June to August): very low monthly precipitation means (0.1 to 0.5 mm/day); schedule steep climbs in Alfama and Graça for morning or evening shade.
- Spring and autumn: bring a light windproof layer for exposed riverfront promenades in Belém and late-afternoon miradouros.
- Late autumn and winter (November to February): pair clear windows at viewpoints with tiled palaces, museums and covered markets when Atlantic fronts pass.
