**Sažetak**

Differences between true mean daily, monthly and annual air temperatures T0 (equation (1)) and temperatures calculated with three different equations ((2), (3), (4)) (commonly used in climatological practice), were investigated at three main meteorological Croatian stations from 1 Jan. 1999 to 31 Dec. 2011. The stations are situated in the following three climatically distinct areas: (1) Zagreb-Grič (mild continental climate), (2) Zavižan (cold mountain climate), and (3) Dubrovnik (hot Mediterranean climate). T1 (equation (2)) and T3 (equation (4)) mean temperatures are defined by the algorithms based on the weighted means of temperatures measured at irregularly-spaced, yet fixed hours. T2 (equation (3)) is the mean temperature defined as the average of daily maximum and minimum temperature. The equation as well as the time of observations used introduces a bias into mean temperatures. The largest differences occur for mean daily temperatures. The calculated daily difference value from all three equations and all analysed stations varies from -3.73 ºC to +3.56 ºC, from -1.39 ºC to +0.79 ºC for monthly differences and from -0.76 ºC to +0.30 ºC for annual differences.
