Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Children often fail to understand the importance of rest and rehydration.

Carry out every crucial safety measure. People with fair skin may sustain burns in fewer than 5 minutes. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Even on a cloudy day, sunscreen with a minimum SPF of 30 should be used liberally and reapplied often, especially after a swim or outdoor activity. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
