Climate normals or climatological normals are 30-year averages of weather variables like temperature and precipitation for a specific location and time of year, providing a stable reference point for comparing current weather to expected conditions and monitoring climate change. The current base period recommended by the World Meteorological Organization (WMO) is 1991–2020. More information
