摘要：On the thermal comfort of a man staying outdoor during the
summer affect mostly meteorological factors, physical activity and the type
of clothing. The work analyzed external air parameters, such as:
temperature, relative humidity and wind speed, occuring in years
1997‒2016. Meteorological data recorded at the Rzeszów-Jasionka station
allowed to determine, among others, the occurrence of maximum daily and
hourly temperatures of outdoor, the daytime and hourly air relative
humidity, the hourly wind speed, as well as the relationship between these
parameters. In recent years, it has been observed the increase of the
number of hot and very hot days which indicates a warming of the climate.
The duration of series of days with maximum daily temperature above
30°C is also prolonged, which is not comfortable for a person staying
outside. During summer, during hot and very hot days, the average relative
humidity remained below 70%. The daily course of this factor was
characterized by the opposite tendency with respect to temperature. The
wind speed in the summer season varies from 0 to 6 m/s. On a daily basis,
the increase in wind speed occurred in the afternoon hours which is
consistent with the temperature characteristics. The occurrence of wind
during the hottest hours causes a pleasant cooling of the organism.
