Heat index

September's heat index is computed to be a very hot 38°C (100.4°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
The metrics for the heat index are tailored for both shady environments and light winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for 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.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
