city nearly unbearable as daily highs averaging 90˚ F (22˚ C) are common. It tends

Winters are fairly mild, as the city can receive snow, but it never tends to stay
on the ground. During this season, temperatures can fall to about 40˚ F (5˚ C) at
night, but reach about 55˚ F (14˚ C) during days. It is also during the winter months
that Vatican City receives most of its rains and there can be a great amount of
mist early mornings.

dramatically as these seasons near winter. From year to year when the temperatures
change from the hot and dry summers to the cooler and wet winters can be unpredictable.
Despite the unpredictability from week to week, Vatican City
averages daily highs of about 72˚ F (22˚ C) during these seasons.
