🇱🇸Lesotho

Lesotho lies at 28°34′–30°40′S as a small landlocked country (approximately 30,355 km²) entirely surrounded by South Africa — the world's only independent state lying entirely above 1,000 m elevation, with the lowest point at the Senqu (Orange) and Makhaleng confluence reaching 1,400 m, the highest national low-point on Earth.

Known as the Kingdom in the Sky, the landscape is dominated by the Drakensberg (Maloti) escarpment in the east, where Thabana Ntlenyana at 3,482 m stands as the country's and southern Africa's highest peak. This striking high-altitude setting produces a unique climate spectrum despite the subtropical latitude — humid subtropical (Cwb / Cfb) on the western lowland fringes around Maseru, subtropical highland (Cwb) at middle elevations, and an alpine to cold semi-arid (BSk) tendency on the high Drakensberg plateaus, with regular winter snowfall and frosts.

Maseru at 1,600 m averages 5°C in July and 21°C in January with 720 mm rainfall almost entirely in the austral summer October to March. Mafeteng records 5°C in July and 21°C in January with 660 mm. Mokhotlong at 2,330 m averages −1°C in July and 17°C in January with 800 mm, ranking among southern Africa's coldest stations.

Sehlabathebe and the Drakensberg summits average −5°C in winter with regular snow from April to September, while Thabana Ntlenyana summit can reach −10°C with persistent winter snowpack. Major climate events include the severe August 2010 Drakensberg snowstorm, the worst in decades; recurrent severe multi-year droughts including the 2015–16 ENSO-driven event that triggered a national disaster declaration and the severe 2018–19 drought; intensifying summer Senqu River flash floods; accelerating winter snowpack decline reducing dry-season streamflow; and growing exposure of Lesotho's small but climate-sensitive Highlands Water Project to extended drought.

Our archive covers 1 Lesotho cities with daily ERA5 reanalysis data going back to 1940. The warmest July averages occur in Maseru, around 15.7°C, while Maseru records the coldest January nights near 14.4°C. Comparing the last decade against the 1940–1970 baseline, mean temperatures across these cities have risen by about 1.4°C.
