When the burn time is less than 10 minutes, you need to cover them up or have them play in the shade. The UV index for tomorrow is just shy of 14 and we are a month or two from the time of year when it’s highest, you would need medical treatment for a child who played in that and was uncovered all day.
Related: I found the old measure (burn time) much easier to use than the new UV index, and while having it standard across countries is good, it’s not straight forward to convert.
