ABSTRACT This study investigates air temperature trends and variability over the Eastern Province of Rwanda its derived near‐homogeneous zones for 1983–2021. Near‐homogeneous are obtained using K‐means clustering method to classify annual long‐term means rainfall minimum, maximum mean temperatures from 570 grid cells in Province. Changes monthly, seasonal maximum, computed with a 95% confidence interval dynamic linear state‐space model. model effectively captures temporal patterns by linking hidden states that evolve time observed measurements while accounting random fluctuations. Additionally, is assessed standard deviation. In Rwanda, minimum have risen 2.95°C (confidence interval: [1.64–4.45]) 1.87°C [0.61–3.19]), respectively. A significant increase all seasons, June–July–August season presenting highest value 3.37 [1.75–4.81]°C. The not significantly changed. Minimum displays notable nonlinearity time‐varying trends, remaining relatively stable during 1990–2010 before experiencing pronounced warming trend thereafter. Over three identified (1. Northwestern, 2. Central 3. Southeastern), Northwestern Southeastern zones. increases zone, having 4.07 [2.26–6.08]°C. vary little, deviation less than 1°C zone dominant identifies climate change vulnerable areas offering vital insights guide policy decision‐makers supporting affected communities enhancing resilience informing future research.
