Temperature

Irauçuba's October weather, marked by an average high temperature of 33.7°C (92.7°F) and an average low temperature of 24.3°C (75.7°F), is the warmest in the year.

Heat index

The heat index for October is calculated to be a blisteringly hot 43°C (109.4°F). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
Note that heat index values are valued for light wind and location in the shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. 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. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

The average relative humidity in October is 65%.
