Foreca's custom weather symbol sets and warning icons are available for download in SVG and png formats, exclusively for our API clients throught MyAPI page. Symbols and icons are provided free of charge to be used togehter with Foreca’s API data.

The symbol codes work as follows:
Letter (D/N) distinguishes day and night symbols from eachother. We provide different symbols for night and daytime since it can cause confusion if daytime symbols are used to describe night time weather.
