The average heat index in April is estimated at a hot 32°C (89.6°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
