Temperature

October's arrival shows an average high-temperature of a still hot 33.7°C (92.7°F), hardly different from the previous month. During the nights in October, an average low-temperature of 21.8°C (71.2°F) is observed in Ibiara.

Heat index

The heat index in October is calculated to be a very hot 37°C (98.6°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Always opt for UVA and UVB-resistant sunglasses on radiant days.
