The advent of October observes an average high-temperature of a still hot 33.4°C (92.1°F), nearly identical to September's 32.5°C (90.5°F). During the nights in October, Irituia experiences a consistent average temperature of 22°C (71.6°F).

Heat index

For most parts of October, the heat index is evaluated at a blazing hot 48°C (118.4°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

The average relative humidity in October is 77%.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes.

For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
