Rome in May
On Labour Day, 1 May, a big free concert takes place in Piazza San Giovanni. The Italian Open tennis tournament is held at the Foro Italico around the middle of the month. Long evenings leave time for a stroll before dinner, and rainy days become fewer.
Afternoons reached 24°C and nights settled at 13°C, warm enough to linger over lunch outdoors. The temperature swung about 11°C within a single day, so midday and evening called for different clothes. Showers came now and then, about 7 rain days in all, and most of the month stayed dry. Year to year it swung widely, from 1 rain day in 2017 to 16 in 2023.
Long days, up to 15.0 hours of light, left room for a late stroll after dinner. About 1 day a month still climbed past 30°C, the ones where you looked for shade. The warmest year was 2022, with highs averaging 26.9°C, 3.4°C above normal.
