Lesotho Climate – July 2026 Update
Top 5 Cities: Maseru, Teyateyaneng, Mafeteng, Leribe, and Maputsoe
Summary
Lesotho experienced a noticeably mild winter month in July 2026, anchoring a broader warm period as global temperatures reached near-record highs. While high-altitude snowfall briefly dusted the Maluti Mountains, average temperatures across the mountain kingdom remained well above long-term norms. The unseasonable warmth reflects a wider pattern across southern Africa, with winter conditions expected to give way to rising warmth in the coming months.
This month in numbers
July 2026 recorded an average temperature of 5.09°C in Lesotho, standing 1.6°C above the 1961-1990 baseline average of 3.45°C and marking the 10th warmest occurrence of the month in 87 years of records. This contributed to a May-July seasonal average of 6.22°C (+1.7°C anomaly), making it the 6th warmest May-July period on record. Globally, land temperatures reached 15.8°C, ranking as the 3rd warmest July ever recorded, while the three-month May-July period ranked as the 2nd warmest on record worldwide.
What changed
The winter period showed sustained mildness following an unusually warm June, where average temperatures spiked to 6.04°C, a full 2.8°C above normal. Over the longer term, Lesotho's 2025 annual average of 11.79°C stood as its 7th warmest year on record, keeping pace with an overall long-term warming trend of +1.27°C since records began in 1940. While northern hemisphere regions like Western Europe dominated the global warmth rankings during this window, southern Africa maintained a steady elevated thermal baseline through the midwinter months.
What’s driving change?
As a high-altitude territory, Lesotho is strongly influenced by , where mountain environments warm at accelerated rates as snow cover retreats and atmospheric moisture shifts. This thermal response is further amplified because surfaces across the southern African interior. Though brief winter cold fronts produced transient snowfall across the Maluti Mountains during the season, underlying atmospheric warming kept midwinter temperatures well above baseline norms.
Looking ahead
Seasonal forecasts indicate that developing ENSO conditions are likely to bring above-normal temperatures and potential rainfall shifts across southern Africa in the coming months as the region transitions toward spring and summer.

FAQs
FAQs
How is the climate in Lesotho changing?
Lesotho is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
What is the climate like in Lesotho?
Lesotho has a temperate climate (Köppen Cwb: Subtropical highland), with both a warm/cold cycle and a wet/dry cycle through the year. January is typically the warmest month, averaging 17.2°C, while July is the coldest at 4.8°C. Annual precipitation averages around 664mm, concentrated mostly in the wet season.
Where does the climate data for Lesotho come from?
Climate data for Lesotho comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Lesotho climate data cover?
The Lesotho climate profile covers Maseru, Teyateyaneng, Mafeteng, Leribe and surrounding areas. Temperature, rainfall and emissions data for Lesotho
How often is the Lesotho climate update refreshed?
The Lesotho climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
What counts as a Heatwave Day on the Lesotho climate page?
Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.
Does the Lesotho climate page include frost and snow data?
Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
