Weather in October
Temperature
The arrival of October sees a recorded average high-temperature of a still hot 33.6°C (92.5°F), showing little divergence from the previous month's conditions. The average temperature during October nights dips to a warm 25.6°C (78.1°F).Heat index
October's heat index is estimated at a burning hot 46°C (114.8°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Always consider that heat index estimations are for light winds and places in the shade. 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 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. 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. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
