FAQ
What is the UV index in Morfa today?
The UV index in Morfa today is low with values around 1. UV strength is shaped by the sun’s elevation, cloud thickness and atmospheric clarity.
When is UV strongest in Morfa?
The peak UV window in Morfa is close to midday, as solar elevation peaks. Values rise most in late spring and summer as solar angles increase.
Can UV be high when it’s cloudy in Morfa?
Yes. Even when it looks cloudy, UV can still reach the surface, particularly through thinner cloud layers. Bright or hazy conditions can still produce notable UV, particularly in late spring and summer.
What does the UV index number mean for sun safety?
The UV index describes the potential for skin damage from ultraviolet radiation. As the number rises, skin damage can occur more quickly in direct sun, so shade, clothing and sunscreen become more important.
Does UV in Morfa change a lot day to day?
Sometimes, yes. Short-term changes usually come from cloud cover and atmospheric haze, whereas the larger seasonal cycle tracks solar elevation across the year.
