Temperature

In Juarina, Brazil, the month of September is known for its highest average temperatures, reaching a high of 37.2°C (99°F) and a low of 23.8°C (74.8°F).

Heat index

Throughout September, the heat index is calculated to be a blisteringly hot 42°C (107.6°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
