Understand that the heat index values take into account shaded locations and mild winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

In June, the average relative humidity is 77%.

Note: During June, 7 as the daily maximum UV index converts into the following advice:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Stay sun-safe with clothing that is both closely woven and worn loosely. Take caution! The UV rays from the Sun gain strength from sand and water reflections.
