The yearly as well as seasonal trends of four atmospheric parameters gathered for the period 1981-2016 were examined in this study for ten weather stations around Adelaide city, South Australia. The non-parametric Mann-Kendall and Sen’s slope estimator techniques were utilized to establish the pattern of trend. Increasing trends were observed in the maximum and minimum temperature in the summer, spring and annual seasons. In addition, no considerable trend was observed in rainfall distribution. Solar radiation revealed a reducing trend in the winter, spring and annual seasons. Considerably rising trends had actually been observed for minimum as well as maximum temperature in Adelaide. An insignifi cantly increasing trend was observed in the rainfall throughout the duration of 1981-2016 just in the summertime as well as in the autumn season. In addition, a dramatically lowering trend in the solar radiation was observed throughout the autumn period, while majority of the trends in the various other periods had not shown any kind of considerable variation. The surge in the minimum as well as maximum temperature of the city was attributed to the climate change phenomenon brought on by growing population and also fast urbanization in the recent past.
