UV Index by City

Low latitude and strong sun push the summer index to extreme; midday is shade-first for most skin types.

Desert clarity means very little UV is filtered — extreme readings are common through the long summer.

Tropical latitude gives some of the highest UV in the US — extreme most clear days, year round.

High desert sun and thin cloud cover make extreme summer readings the norm rather than the exception.

Afternoon storms can break the heat but UV is extreme before they arrive — check the hourly curve.

Gulf humidity can make the day feel hazy, but summer UV still reaches extreme before afternoon storms build.

Beach reflection and low latitude make the UV stronger than the sea breeze suggests, especially near midday.

Atlantic exposure keeps beach days bright; use UV, not temperature, to decide when to shorten a tanning session.

Desert clarity and elevation make extreme UV common; the heat is obvious, but the UV dose climbs even faster.

Clear desert skies mean little UV filtering; shade-first planning matters long before the hottest hour.
