Abstract: Trend analysis of temperature on a local scale provides vital clues to the changes in amplitude with time and possibly the reasons for the changes. The present paper attempts to examine the temporal and seasonal trends in temperature of a developing township, Pattambi, Kerala in India from 1950 to 2018. We used Mann-Kendall rank statistics to examine the historical temperature data. The results show a general increase in annual temperature, especially the mean annual maximum temperature of the region across the year with a statistically significant increasing trend. The same trend could be seen in the case of southwest monsoon temperature. Another notable observation from the study is the statistically significant decrement in the winter temperature of the region. The regional changes in the temperature will have much impact on the economy and society in the area since the local livelihood is heavily dependent on agriculture.

Keywords: Kerala; Pattambi; historic temperature data; Mann-Kendall rank statistics; trend analysis.
