The ultraviolet index, or UV Index, is an international standard measurement of the strength of sunburn-producing ultraviolet (UV) radiation at a particular place and time.
The risk of harm from unprotected sun exposure is categorised by five numerical and colour coded values. The higher the number, the stronger the UVR and the less time it takes damage to occur. To view the sun protection advice based on the five categories of the UV Index, select each option below.
The UV Index forecast is supplied to us by OpenWeather - a team of IT experts and data scientists that have been practising deep weather data science since 2014. They provide us with forecasted stratospheric ozone concentration and forecasted cloud cover, which we then combine with location information provided by google to determine elevation of the ground, enabling us to calculate historical, current and forecasted UV Index data for any location across the globe.
