Heat index

The heat index for October is appraised at a very hot 38°C (100.4°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 hold great significance to children. 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Keep in mind that shade structures may not provide complete protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
