Heat index

December's average heat index is calculated to be a very hot 37°C (98.6°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Heat index evaluations are typically in the context of light winds and shaded environments. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
