This study aims to analyze trends in changes in the averages of summer maximum temperatures in the Al-Haruj Mountains region in central Libya during the period (1981–2024), based on data from 11 observation points represented by the NASA POWER platform. For comparison purposes, the time series was divided into two periods: (1981–2002) and (2003–2024). The study employed the T-test to measure the statistical significance of differences between the two periods, in addition to thermal threshold analysis using percentiles, with spatial representation of the data through the Kriging method within spatial interpolation tools in the ArcMap GIS environment. The results showed statistically significant differences at the level of (P = 0.031) between the two periods. The analysis of the 90th percentile (43.68°C) also indicated an expansion in the range of higher values compared to the reference period. Spatially, the interpolation results suggest a relative decrease in temperature values over elevated areas, in contrast to an expansion of higher values toward lower areas. The study concludes that there is a general trend toward an increase in summer maximum temperatures in the region, with potential implications for ecosystems and water resources, which necessitates taking these changes into account when developing adaptation strategies.
