We include some information on the climate or, more likely, "climates", as Abruzzo has two climates: maritime and continental. The annual average temperature varies from 8°-12° in the mountainous area to 12°-16° in the maritime area; in both areas, though, the differences between maximum and minimum temperature can be considerable. The coldest month is January, when the average temperature on the coast is 8°, while in the interior it often drops below zero.

In the summer the average temperature of both areas are similar: 24° on the coast, 20° in the interior. The slight difference is due to the overheating of the rocky areas in the interior and the consequent letting out of the heat during the night, mitigating the lower temperatures caused by the altitude. In the more internal areas, mainly in the most elevated basins, besides the annual thermal changes, there are also noticeable daily changes, that is a marked difference between the day and the night temperature.

Also the distribution of rainfall, mainly determined by the mountains and their location, varies according to the area. The rainfall reaches its maximum, in the whole region, in the month of November and the minimum in the summer. On the mountains the rainfall becomes snow lasting on the ground for different periods, according to different altitudes: an average of 38 days, in the area of L'Aquila, at an altitude of 55 to 1000 mts., 190 days at 2000 mts. and throughout the year on the peak of the Corno Grande.
