The Sun Awareness. Reinvented.

  • UV Index Forecast calculation is based on the publications of The Royal Netherlands Meteorological Institute (KNMI) and The National Institute of Water and Atmospheric Research (NIWA) of New Zealand.

  • The clear sky UV Index is real-time corrected by sun-earth distance and is optionally altered by clouds absorption and area reflection factors. The UV calculation has never been so easy and accurate.

  • Based on a personally chosen skin type from the Fitzpatrick phototyping scale UVIMate is able to recommend you the best possible UV protection exactly in a time you'll need it most.


When it comes to sun protection, prevention is key.
