Data & methodology
The diagrams use the free global dataset CHELSA (Climatologies at high resolution for the earth's land surface areas). These high-resolution data cover the period 1981-2010, and pixel size is less than one square kilometer.
Karger, D.N., Conrad, O., Böhner, J., Kawohl, T., Kreft, H., Soria-Auza, R.W., Zimmermann, N.E., Linder, P., Kessler, M. (2017). Climatologies at high resolution for the Earth land surface areas. Scientific Data. 4 170122. https://doi.org/10.1038/sdata.2017.122
The diagram uses D3.js in an ObservableHQ notebook (Climate Diagrams). The map is a Leaflet map, geolocation is done by LocationIQ.
There are also other diagram variants — a Walter-Lieth climate diagram (the classic scientific diagram form: 1:2 temperature/precipitation scale, compressed above 100mm, with humid/arid shading, described on Wikipedia) and a Klimogramm (monthly temperature/precipitation pairs plotted as a chronologically connected loop).
The climate classification (Köppen-Geiger, Cannon, Trewartha, Defaut 1996, Thornthwaite-Feddema, Whittaker) is done using pyZonae by Didier M. Roche, Didier Paillard and G. Bonneroy, a modernized merge building on the original pyKoeppen.

Frequently asked questions
What is a climate diagram?
A climate diagram (also called a climate graph, climograph or climate chart) shows the average monthly temperature as a line and the average monthly precipitation as bars for one place. It shows at a glance how warm, wet or dry each month typically is.
How do I create a climate diagram?
Search for a place or click anywhere on the map. The diagram for that location appears immediately, together with its Köppen-Geiger climate classification. You can download it as a PNG image or share a link to it.
Is it free?
Yes. climate.mapresso.com is free, without registration and without ads. It is an independent project supported by donations.
Which data are used?
The long-term averages come from CHELSA V2.1 (Karger et al. 2017) for the reference period 1981–2010, at a resolution of about 1 km. This works for any land location on Earth, including places without a weather station.
Which kinds of diagrams are available?
The classic climate diagram, a Walter-Lieth climate diagram and a Klimogramm (thermopluviogram), a side-by-side comparison of two locations, and an experimental view comparing the current year (ERA5-Land) with the long-term normal.
Can I embed the diagram or use the data?
Yes. A diagram for any coordinates can be embedded on your own website as an iframe, and the monthly climate data and the climate classification are available through a free API.
