About Climate Zone Map

An interactive Köppen-Geiger climate zone map of the world. Tap or search any place to see its climate zone in plain English, what it was in 1901 to 1930 and how it is projected to change by 2100.

Climate Zone Map is a free, single-purpose website. It is built to be useful on its own: you can explore the map, share a link to exactly what you are looking at, embed it on your own page or download an image of it. Everything is made from open data, and the credits are on the data sources page.

Who runs it

This site is run by Chris Barnes, a sole trader (England and Wales). It is one of a small family of map sites; you can find the others in the "More maps" list at the bottom of every page.

How accurate is it?

We show the data as its authors published it, and we try to be honest about how certain it is. Where something is a best guess, the map says so. If you spot a mistake in how we display or describe the data, please tell us.

How it is paid for

The site is free to use. It may show adverts, and it offers an optional email newsletter. We do not sell your personal data.

Why this site exists

Most climate zone maps are small pictures in a textbook. This one lets you tap your own street, see the zone in words, and compare it with the past and with the end of the century under three emissions scenarios.

How the map is made

The maps are the 1 km Köppen-Geiger maps of Beck et al. (2023). We re-draw each map as map tiles, keeping the dataset's own colours, and read the class back from the tile under a tap, so the card always agrees with what you see. Figures on the zone, country and city pages are worked out from the same files. See the data sources page for the citation and licence (CC BY 4.0).

What the map does not show

It does not show weather or give a forecast. The 2071 to 2099 maps are model projections under emissions scenarios, and the 1901 to 1930 map is a reconstruction. A tap near a class boundary can differ from the cell next door.
