Summer is extremely hot, and therefore, not the best time for a visit to Rome. Midday and afternoon temperature exceed 35 degrees °C, so it’s better to stay indoors then. July and August are the hottest months of the year. Summer also has the least number of rainy days. Afternoon breeze, called "ponentino", blows in the areas that are closer to the sea, providing some relief.
In August life in Rome seems to slow down considerably, as many locals temporarily close up their business. Occasional thunderstorms take pace in the afternoon, particularly in the northern and eastern parts of the city, further from the sea.
