In July, the average heat index is appraised at a tropical 87.8°F (31°C). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
