the average temperature on earth is about 61 degrees f 16 c but temperatures vary greatly around the world depending on the time of year ocean and wind currents and weather conditions summers tend to be warmer and winters colder also temperatures tend to be higher near the equator and lower near the poles
Today's global temperature is typically measured by how it compares to one of these past long-term periods. For example, the average annual temperature for the globe between 1951 and 1980 was around 57.2 degrees Fahrenheit (14 degrees Celsius). In 2015, the hottest year on record, the temperature was about 1.8 degrees F (1 degree C) warmer than the 1951â1980 base period. That calculation comes from NASA and NOAA.
