UV index in Ho Chi Minh City

Ho Chi Minh City lies at 11°N. The midday sun reaches 86.3° above the horizon in Ho Chi Minh City today, and twice a year it passes straight overhead. Elevation is what sets the ceiling for UV, and over Ho Chi Minh City it is so steep that the rays take the shortest possible path through the atmosphere, and the index can reach extreme values.

What is the UV index?

The UV index is an international scale describing the strength of the sun's ultraviolet radiation at ground level. It starts at 0 and is effectively open-ended — at mid-latitudes it rarely exceeds 8, while in the tropics and high in the mountains it can pass 11. The higher the number, the less time it takes to get sunburnt.

The UV index depends mainly on how high the sun is in the sky. That is why it peaks around solar noon and is greatest in summer near the longest day of the year. Clouds, ozone, altitude and reflection from snow or water also affect the value.
