UV Index Today is a free sun-safety tool. We show a live UV index for your approximate location, a short forecast window, and practical notes so you can decide when shade, clothing, or sunscreen matter.

Who writes this

Guide and Blog pages are written and updated by the UV Index Today editors—the same people who run the live index, city pages, and SPF calculator. We are not a dermatology clinic and we do not put a doctor’s name on pages we have not had clinically reviewed. Health claims on those pages are tied to named public sources (WHO, FDA, EPA, IARC, AAD, and others) with outbound links.

That is deliberate. A fake byline would be worse for trust than an honest organizational one.

Who this site is for

Anyone who spends time outdoors—commuters, runners, parents, travelers, and people managing sun-sensitive skin. The goal is simple: check the number before you go out, then act on it.

What you get

• Current UV index and today's peak estimate for your area
• A next-few-hours UV outlook to plan midday exposure
• Region and city pages to compare places
• An SPF calculator from skin type plus today’s index
• A Guide of short Q&A pages and a Blog of planning notes

How Guide and Blog are sourced

• Lead with the answer. No “introduction” filler and no keyword stacking.
• Numbers that matter for planning (SPF, UV bands, albedo, altitude) come from the linked agency or paper—not from “studies show.”
• Each article shows a published date, an updated date when we revise it, and a Sources list.
• We do not invent personal anecdotes, quotes, or local UV values. Live readings on the homepage are estimates for planning.
• Off-topic germicidal / gadget pages (bed bugs, nail lamps, plant grow lights) were removed; those URLs redirect here or to a related sun-UV page.

How to use the readings

Treat the UV index as a planning signal, not a medical diagnosis. Low (0–2) usually needs little protection. Moderate to high (3–7) calls for shade, clothing, and SPF 30+. Very high and extreme (8+) means minimize midday sun and reapply sunscreen. Surface reflection from water, sand, and snow can raise your effective dose.

Limits

UV conditions change with clouds, altitude, and time of day. Readings are estimates for sun-safety planning. They are not a substitute for medical advice, dermatology care, or common sense. When in doubt, protect your skin.
