Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

July through October, with an average relative humidity of 88%, are the most humid months.

Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
