Abstract The change in the air temperature recorded at the Genoa University observatory over 155 years followed the change in the wind direction. A warming occurred both from 1838 to 1869 and from 1890 to 1950. The latter warm period was followed by a cooling in the 1950s, when the lowest mean annual temperature occurred. Generally, a warm period corresponds to a growth in the southern components of the ground wind direction; the increase in the southerly circulation in the Mediterranean yields increased stability in dry weather. Temperature-depth data measured in a geothermal borehole reflect this climate change. A comparison between the measurements and a synthetic temperature profile, based on the air temperature history recorded at the observatory, indicates that the average temperature prior to the meteorological time series was about 0.6 K higher than the average of the decade 1973-1982.
