At latitudes above 41 ° the Italian localities have annual averages very similar to those in Spain, if not higher in some cases.
this is due to generally warmer summers in Italy above this latitude, and similar winters.

Usually below the 41st parallel the Iberian localities have annual averages higher than the Italian and Greek ones.
Exceptions are some Sicilian localities that hold up the comparison thanks to particularly mild lows especially in the cold semester, such as Messina, Palermo and Capo Sparrow.
The coastal areas generally enjoy milder winters, while the Spanish inland areas enjoy warmer summers.

Spain and peninsular Italy have different rainfall distribution by month. In peninsular Italy the two wettest months are usually November and December, so we can define a late-autumn peak, while in Spain November is drier than October and September. In Spain the spring is wetter than winter, we can observe a secondary minimum in late-winter (February and March), before a rainfall growth in April and May, while in Southern Italy, in the second part of spring, the amount of rainfall begins to decrease, before the usual summer drought
