Cloud cover
Cloudy days deceive many people into thinking the danger of UV radiation is minimal. Cloud affects the strength of radiation reaching the ground in complex ways. Most clouds block some UV radiation, but the degree of protection depends on the type and amount of cloud. Some clouds can actually increase the UV intensity on the ground by reflecting and refracting the sun's rays. People can also be caught unawares when a small break in an overcast deck of clouds allows a brief burst of intense radiation to reach the ground.
The table above contains the highest expected UV Index values under various cloud conditions between about 11 am and 2 pm local time. The maximum UV Index is that expected with clear and sunny conditions. For a colour graph of the UV Index during the day, in clear sky conditions, please click the location name in the left hand column.
| Definition for amount of cloud | |
| Broken | - some breaks in the cloud but more than half the sky remains covered |
| Overcast | - sky totally covered by cloud |
