UV Index

What is the UV index?

The UV index is a standard measurement of erythemal (sun-burn causing) UV intensity that gives a more objective measure than the old “time to burn” (which cannot account for skin tone). The scale is open-ended, but a UV index of greater than 10 is extreme and a UV index of less than 1 is low. more info

Current UV Index at the Nassau sites

Graphs showing predicted and measured UV Index at Nassau International Airport are updated at 30 minute intervals. Unlike the UVI predictions seen on TV, these include the effects of clouds. The most recent UVI is displayed, along with a corresponding behavioural message. We plan to make similar data from other sites available in this way at a later date but currently data are downloaded from most instruments elsewhere only once per day.
