Mumbai's lowest UV of the year falls on 10 July, in the middle of summer. The monsoon does what winter does everywhere else. A year of noon UV over South Asia, one frame a day, every place at its own local solar noon.
In mid-July the midday sun over Andalusia and the Aegean pushes the UV index past 9. Northern Scandinavia barely clears 3 at the same hour. A year of noon UV over Europe, one frame a day, every place at its own local solar noon.
