View historic, real recorded climate data from 1980 until recently (up to the end of last year). The gridded data (0.5 x 0.5°) has been compiled by the Climatic Research Unit (CRU) at the University of East Anglia, UK by combining, validating and interpolating available weather station data into a global grid. We have calculated and included the relevant Heat Stress Indices mentioned above. This page also provides the raw data from approximately 5000 global weather stations, which have approximately 70% complete recordings since 1980.
