The city's greenway network, university campuses, and outdoor-heavy culture mean residents log substantial sun time, and the mild climate makes it easy to underestimate exposure during shoulder-season months like April and October.

Raleigh's humid subtropical climate brings hot summers and mild, changeable winters. Midday UV index values reach 9-10 on clear days from May through August and remain in the high range through September. Humidity builds through the summer, and while afternoon haze is common, it filters visible light far more than UV — a clear-looking summer sky and a milky one deliver similar burn risk.

- Summer: Very High (8-10)
- Spring/Fall: Moderate to High (5-8)
- Winter: Low to Moderate (2-4)
- Peak UV hours: 10 AM - 4 PM
