The objective of the research was the climatic zoning of the Mayarí municipality; Lang Index was the estimation by use of data from meteorological station and WorldClim 2. The monthly images of precipitation and average temperature provided by WorldClim 2 were used with a spatial resolution of 30 seconds in the system of WGS 1984 EPSG coordinates: 4326. The images were processed in ArcGIS 3.10 software; and in the Raster Calculator option, the Lang Index was obtained. For the extraction of the values, a representation of 40 random points was made that covered the entire region under study, separated at a distance of 10 km. It was determined by linear regression in the STATGRAPHICS Plus 5.0 software; the relationship between Lang Index estimated by WorldClim 2 and that calculated with data from the Guaro meteorological station located in Mayarí municipality. The use of WorldClim 2 showed the existence of three climatic zones (arid, semi-arid and semi-humid). Its estimation had a high determination and correlation for the calculated values of said index, which allows it to be used in territories where there is a low number of meteorological stations for taking climatic data.
