FAQ
What is the UV index in Arncliffe today?
Today in Arncliffe, UV levels are low and sits near 2 at its peak. Ultraviolet intensity is controlled mainly by the height of the sun, cloud cover and air clarity.
When is UV strongest in Arncliffe?
UV in Arncliffe is strongest around the middle of the day, when the sun reaches its highest point. Levels are also highest in late spring and summer, when the sun is higher in the sky across the UK.
Can UV be high when it’s cloudy in Arncliffe?
Yes — cloud is not a guarantee of low UV. Cloud doesn’t always block UV effectively — especially with patchy cloud and brighter summer light. This is most relevant in summer and around the middle of the day.
What does the UV index number mean for sun safety?
The number indicates how quickly unprotected skin may be affected in sunlight. A higher index indicates faster potential skin damage in sunshine; sensible protection becomes more worthwhile as values increase.
Does UV in Arncliffe change a lot day to day?
It can. Day-to-day swings are mainly driven by cloud patterns, haze and air mass changes, while seasonal shifts are slower and follow the sun’s height through the year.
