Historical climate data

This is WorldClim version 2.1 climate data for 1970-2000. This version was released in January 2020.

There are monthly climate data for minimum, mean, and maximum temperature, precipitation, solar radiation, wind speed, water vapor pressure, and for total precipitation. There are also 19 “bioclimatic” variables.

The data is available at the four spatial resolutions, between 30 seconds (~1 km2) to 10 minutes (~340 km2). Each download is a “zip” file containing 12 GeoTiff (.tif) files, one for each month of the year (January is 1; December is 12).

Below you can download the standard (19) WorldClim Bioclimatic variables for WorldClim version 2. They are the average for the years 1970-2000. Each download is a "zip" file containing 19 GeoTiff (.tif) files, one for each month of the variables.

For reference, here is the elevation data that was used to produce WorldClim 2.1. These were derived from the SRTM elevation data.

The development of WorldClim v2 was supported by a grant from Feed the Future to the Geospatial and Farming Systems Consortium of the Sustainable Intensification Innovation Lab.


This version supersedes version 1.4, which is still available here.
