The paper analyzes the air temperature characteristics in Bosnia and Herzegovina in order to identi-
fy recent trends in mean air temperature. Trends in annual, seasonal and monthly mean air tempera-
tures during 1961–2015 periods were determined based on data from sixteen meteorological stations.
MAKESENS procedure (Salmi, et al., 2002), which uses the nonparametric Mann-Kendall test and the
nonparametric Sen’s method, was applied on time series of annual, seasonal and monthly mean air
temperatures to assess the trend magnitude and its statistical significance. Given the results, the warm-
ing trend is present all over Bosnia and Herzegovina. Significant positive trends in annual and summer
temperatures were detected over the entire territory (p<0.01). Positive winter and spring trends are
largely significant (p<0.01 or p<0.05), whereas autumn trends are low and insignificant. The highest in-
crease was registered in June–August and December–January periods. In some areas, a low negative
trend was present in September and November. A significant positive correlation between East-Atlan-
tic pattern index and temperature was determined over the entire territory of Bosnia and Herzegovina
throughout the year. Winter and spring temperatures were also significantly related to the North Atlan-
tic Oscillation index and Arctic Oscillation index, respectively.
