Heat index

October's mean heat index is evaluated at a torrid 39°C (102.2°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
