How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
When to go, and what to expect
Spring (Mar–May)
Ideal for walking the historic centre before the heat — May is a standout.

June is superb; July and August suit only those who don't mind heat and crowds.
Autumn (Sep–Nov)
September and October are prime months; November turns damp.
Winter (Dec–Feb)
Fine for museums, pizza and low-season calm, less so for the coast.
