El Niño 2026–27 in Lesotho
Odds favour a drier-than-normal December–February in Lesotho (67% chance). Past El Niño years show no consistent rainfall pattern here.
Temperatures: likely warmer than the 1993–2016 average (100% chance).
El Niño status: El Niño Advisory (NOAA, 12 November 2026). Outlook: Copernicus, issued November 2026.
Outlook for the next six months
December–February
Rainfall: likely drier
Temperature: likely warmer
February–April
Rainfall: likely drier
Temperature: likely warmer
Away from the tropics, seasonal rainfall forecasts have limited skill. Treat small shifts in the odds as weak signals. “Normal” means the middle third of the model's own 1993–2016 range; because the climate has warmed since then, “warmer” is the usual result almost everywhere.

Official warnings
Official warnings (WMO Severe Weather Information Centre)
This is not an official forecast or warning. Seasonal outlooks give odds, not certainties. For warnings and decisions about safety, follow your national weather service.
What you can do
If it turns out drier
- Follow water-use notices from your local water utility, and fix leaks early.
- Farmers: check planting advice and drought bulletins from the national agriculture and weather services before the season.
- Clear dry vegetation near homes where wildfires are possible, and know your local fire-danger rating.
- Keep a few days of drinking water stored if supply cuts have happened in past dry years.
If it turns out hotter
- Check on older relatives, neighbours and anyone who lives alone during hot spells.
- Drink water regularly, and avoid hard outdoor work in the hottest hours.
- Know the signs of heat exhaustion (dizziness, headache, nausea) and when to get medical help.
