Important Safety Information

General Guidelines

These exposure times are estimates based on scientific research and should be used as general guidelines only. Individual responses to UV exposure may vary.

Affecting Factors

UV exposure is affected by: time of day, season, altitude, cloud cover, reflection from surfaces, and individual skin sensitivity.

Protection Tips

For proper sun protection: seek shade during peak UV hours (10 AM - 4 PM), wear protective clothing, use broad-spectrum sunscreen, and monitor the UV index regularly.

Medical Advice

Consult with a healthcare provider for personalized sun protection advice, especially if you have a history of skin conditions or are taking medications that may increase sun sensitivity.

SUNSET & SUNRISE

Miami's UV Climate

Miami, located in southeastern Florida, experiences a tropical monsoon climate with extremely high UV exposure throughout the year. The city's southern location, low elevation, and proximity to the equator result in some of the highest UV radiation levels in the continental United States. The combination of year-round warm weather, abundant sunshine, and outdoor lifestyle makes comprehensive sun protection essential for residents and visitors, especially during beach activities and outdoor recreation.

Climate and UV Patterns

Miami's tropical climate creates unique UV exposure patterns with high to very high UV levels year-round. The city receives intense UV radiation due to its proximity to the equator, with UV index values frequently reaching 10+ during peak hours. Local weather radar shows that while afternoon thunderstorms are common, they typically occur after peak UV hours, meaning residents still face significant sun exposure. The high humidity can also create a false sense of protection, as UV rays penetrate cloud cover effectively.

UV Index and Health Impact

Understanding UV radiation levels is crucial for protecting your health. The UV index in Miami-Dade County varies throughout the year:

  • Summer (April-September): High to Very High UV (7-10+)
  • Spring/Fall: Moderate to High UV (5-7)
  • Winter: Moderate UV (4-6)
  • Peak UV hours: 10 AM - 4 PM
  • Cloudy conditions: UV reduced by 20-40%
  • Clear skies: Maximum UV exposure
  • Visibility conditions affect UV intensity

Local Weather Patterns

Miami's weather patterns significantly influence UV exposure throughout the year. The city experiences distinct wet and dry seasons, with the dry season (November to April) typically featuring clearer skies and higher UV exposure. During the wet season (May to October), afternoon thunderstorms can temporarily reduce UV levels, but morning and early afternoon hours still present high exposure risk. The city's coastal location means sea breezes can provide some relief from heat but don't reduce UV radiation. Hurricane season (June to November) can bring extended periods of cloud cover, but UV exposure remains significant during clear periods.
