Weather in October
Temperature
October is the month that records the highest temperatures, with averages ranging from a high of 34.9°C (94.8°F) to a low of 20.8°C (69.4°F).Heat index
Throughout October, the heat index is appraised at a blazing hot 51°C (123.8°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
