For example in Perth, WA today the UV was only “1 – Low” at 6pm, when the sun was still quite high in the sky. The temperature was still 34 degrees and you could really feel the sun’s heat.
How could you be at such low risk of sunburn under those conditions?
In: Planetary Science
UV index isn’t just based on cloud cover and location of the sun in the sky, it’s also very dependent on atmospheric conditions. It’s likely that some invisible conditions existed that was able to block the UV, like above average concentration of ozone. In fact, you can still get sunburn on an overcast day, so even cloud cover doesn’t necessarily decrease UV index.
Temperature however has absolutely nothing to do with UV index.
