Meteorological data of all International Tennis Federation Junior tournaments held during 2010-2019

We collected data on the environmental conditions in which all International Tennis Federation (ITF) Junior tennis tournaments were held during the last decade (2010-2019). The dates and locations of all ITF Junior tournaments were collected from the official ITF calendar in www.itftennis.com. Meteorological data (air temperature, relative humidity, wind speed, cloud cover) from the closest weather station to each tournament were collected from the National Oceanic and Atmospheric Administration database (https://www.ncei.noaa.gov/metadata/geoportal/rest/metadata/item/gov.noaa.ncdc:C00532/html) to calculate the wet bulb globe temperature (WBGT).
