Weather Icons

What Weather Icons is
Weather Icons is a free, open-source icon font and CSS collection containing 222 weather-themed icons for web projects and other designs. CSS supports scaling, rotation, flipping, recoloring, shadows, and fixed-width display, while utility classes provide 90-, 180-, and 270-degree turns. OTF and TTF files let users copy icons into Photoshop, Illustrator, or Sketch. The set includes 28 moon phases, 12 clock hours, the Beaufort wind-force scale, and maritime wind warnings. Mappings are listed for Yahoo Weather, OpenWeatherMaps, Forecast.io, Weather Underground, and the World Meteorological Organization. Less and Sass/SCSS files support existing build systems. Wind indicators need the companion weather-icons-wind CSS file. Licensing lists SIL OFL 1.1 for icons, MIT for code, and CC BY 3.0 for documentation. Commercial use is allowed, but no API access is listed.
