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.

Desert clarity filters little UV; extreme readings are routine through the long Sonoran summer.

Gulf-coast sun and low latitude push the summer index to extreme before afternoon storms build.

Colorado Springs elevation can strengthen UV relative to lower locations at the same latitude; cooler mountain air does not mean lower UV, so check the current index.

High humidity feels hazy but does little to filter UV, so the low-latitude midday peak still reaches 'extreme' on the EPA scale; treat any tanning time here as a risk-managed estimate.

As the southernmost US city near 24.5 degrees north, the sun climbs nearly overhead in summer and ocean reflection compounds it, so UV regularly hits the EPA 'extreme' ceiling; this is an estimate, not medical advice.

High-desert elevation and dry, clear air can strengthen UV; use the current index and protect at UV 3+ rather than judging exposure from temperature.

Low desert latitude, higher elevation, and very dry, clear skies can combine with extreme summer UV; consider the typical peak a conservative reference, not a safe-time promise.

Central Valley summers bring relentless cloud-free skies that let UV build to the 'extreme' band by midday; dry heat does not lower UV, and these figures are estimates, not medical advice.
