The table is Roma Fiumicino, WMO 16242, the coastal airport station, from Italy's 1991–2020 submission in the WMO normals distributed by NOAA NCEI. Roma Ciampino is closer to the city and its temperature normal is complete, but its precipitation normal is blank for June, July, and August. We do not fill those months. Fiumicino is the station with a full precipitation row, and the caption says it is the airport.

Florence and Venice have their own stations. A summer plan for Rome is not a summer plan for Venice, where the March maximum in the Tessera file is blank and is left blank. Italia.it's tipping note and the Codice della Strada rule are national and are repeated on the city sheets.

Month by month

The highest average daily high is 30.02°C in August. The lowest average daily low is 3.43°C in January. The heaviest month in the water column is November at 98.93 mm, and the lightest is July at 12.31 mm. These sentences only restate the table. They are not a ranking of the best month to go.

The rule runs from that month’s average low to its average high, on this station’s own scale. The black bar under the water figure is that month against the wettest month here.
