Yes, Florida experiences some of the highest levels of ultraviolet (UV) radiation in the continental United States. Its subtropical location means the sun's rays strike more directly, and the state's high humidity and proximity to water can reflect and intensify UV exposure. This persistent intensity is a year-round concern, not just a summer issue. For residents, this underscores the critical importance of sun protection and also highlights a significant indoor air quality consideration. High UV levels can degrade HVAC components and allow more biological contaminants to thrive inside ductwork. For a deeper look at how this affects home systems, particularly regarding indoor air quality solutions, see our internal article UV Lights in Orlando, FL.
The Nights of Lights in St. Augustine is not a free event. While you can view the spectacular light displays from public streets and the bayfront for free, most activities and tours associated with the festival require paid admission. Access to many prime viewing areas, such as from the water on a boat tour or from above on certain trolley or train tours, involves purchasing tickets. Some attractions and historic sites that are part of the experience also have their own separate entry fees. For the best experience, budgeting for a guided tour is recommended, as it provides context and access that enhances viewing the millions of lights.
Ultraviolet (UV) radiation from the sun is typically at its highest intensity during the middle of the day, specifically between the hours of 10 a.m. and 4 p.m. This is when the sun is at its highest point in the sky, and its rays have the shortest distance to travel through the Earth's atmosphere, resulting in the strongest UV exposure. The UV Index, a standard measurement of the sun's UV radiation strength, often peaks around solar noon. It is crucial to take sun safety precautions during these hours, such as seeking shade, wearing protective clothing, and applying broad-spectrum sunscreen, even on cloudy days, as UV rays can penetrate cloud cover.
