Read the numbers correctly
Climate, not a promise.
These patterns help compare months. They cannot tell you the weather on a specific day of your trip.
Sources, method and limitsHow these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Acilia-Castel Fusano-Ostia Antica) is explained once on the Acilia-Castel Fusano-Ostia Antica year overview and on the Sources, method and limits page.
Fiumicino lies in the same rainfall cell, so its rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
