Climate is a decisive tourist resource and must be taken into account in tourism promotions because it plays a key role in the attractiveness of tourist destinations and seasonality in tourist demand. The climate leaflet contains climatological and bioclimatological data, presented for tourists. Bioclimatological conditions are shown using mean values and the frequency of thermal sensations based on physiological equivalents, temperature is measured in 10-day intervals that cover the whole year, along with air temperature, sea temperature, duration of sunshine, amount and number of days with precipitation and wind rose are also measured. . In addition, it contains a scheme that displays climate tourism information. The information provided here helps the tourism industry and participants in making decisions. As for the convenience of the climate, for general tourism purposes, it is expressed by the tourism climate index (TCI), which combines several climate elements related to tourism. In the studies analyzed in this paper, the original TCI was modified in two ways. On the one hand, the most popular and most used bioclimatic index is Physiologically Equivalent Temperature (PET). Furthermore, the TCI was adjusted to a ten-day scale because it is more relevant for tourism than the original monthly averages of climate parameters. Using the modified TCI, we characterize and compare climatically favorable or unfavorable places and periods of the year, taking Hungary and two other relatively close tourist destinations as examples.
