This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .

The red line shows direct surface temperature measurements since 1880. [2] Global surface temperature (GST) refers to the average temperature of Earth 's surface. It is determined nowadays by measuring the temperatures over the ocean and land, and then calculating a weighted average. The temperature over the ocean is called the sea surface ...
Averages. In an average year, the temperature will usually be between 21 °F (−6 °C) and 94 °F (34 °C) with temperatures greatly exceeding these values being uncommon. Temperatures above 97 °F (36 °C) and below 15 °F (−9 °C) are very rare, with the last occurrences being June 28, 2021 and November 24, 2010, respectively.

Definition Climate (from Ancient Greek κλίμα 'inclination') is commonly defined as the weather averaged over a long period. The standard averaging period is 30 years, but other periods may be used depending on the purpose. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations. The Intergovernmental Panel on Climate Change ...
The global average and combined land and ocean surface temperature show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on multiple independently produced datasets. [26] : 5 The trend is faster since 1970s than in any other 50-year period over at least the last 2000 years.
Annual rainfall in Snowdonia averages between 3,000 millimetres (120 in) (Blaenau Ffestiniog) and 5,000 millimetres (200 in) (Snowdon's summit). The likelihood is that it will fall as sleet or snow when the temperature falls below 5 °C (41 °F) and snow tends to be lying on the ground there for an average of 30 days a year.
