Residents and visitors in Peoria, AZ, and surrounding areas should be aware of the health risks associated with high UV exposure. Prolonged exposure during peak hours, especially between 12:00 PM and 3:00 PM MST, can lead to sunburn, skin damage, and increased risk of skin cancer. Sensitive groups, including children and individuals with fair skin, are particularly vulnerable. The UV Index reaching 8.9 (Very High) indicates a need for heightened precautions to avoid harmful effects.
