How to read today’s UV number
EPA groups UV 0-2 as low, 3-7 as moderate to high, and 8+ as very high to extreme. TanPilot turns that band into timing, SPF, and skin-type context instead of leaving you with a bare number.

Look at the hourly curve
The daily maximum matters, but tanning decisions are made by the hour. Morning and late afternoon often have lower UV than the middle of the day.
-
Treat clouds as a caveat, not a shield
WHO notes that UV can remain high under cloud cover. A forecast should show both UV and conditions so you do not infer protection from shade-like weather.
-
Use skin type as an input
Fitzpatrick type helps estimate burn tendency, but it is not a medical diagnosis and does not remove the need for protection.
