<![CDATA[Currently, precipitation and temperature stand as the foremost indicators of climate change, exerting a profound and far-reaching influence on the global environment. This scholarly inquiry endeavors to illuminate the spatial and temporal dynamics of these climatic variables—fundamental markers of seasonal variation in the Kegalle District—spanning 41 years from 1981 to 2024. These datasets were subjected to rigorous trend analysis utilising Minitab, employing the Mann-Kendall test alongside Sen's Slope Estimator to detect and interpret temporal patterns. Among the ten selected localities, Yatiyanthota exhibits the most pronounced temperature fluctuations, with an average of 26.5°C and a minimum of 19.25°C, where temperatures reach 34.8°C. Notably, this region exhibits a decline in maximum temperatures alongside an increase in minimum temperatures. Conversely, Aranayaka maintains a relatively moderate mean temperature of 18.9°C. Rainfall observations reveal that Rambukkana experiences the highest precipitation, with an increase of 1,826 millimeters, whereas Deranyagala records the lowest. On a monthly scale, October and November receive the greatest rainfall, whereas April and March are characterised by minimal precipitation coupled with elevated temperatures. Trend analyses identify Aranayake as the locale with the lowest averages of both temperature and rainfall.Received: 2025-10-16 Revised: 2026-04-29 Accepted: 2026-07-13 Published: 2026-08-05]]>
