Weather in October
Temperature
The arrival of October brings an average high-temperature of a hot 30.7°C (87.3°F), subtly diverging from September's 28.6°C (83.5°F). Bum throughout October, records an average low-temperature of 22.1°C (71.8°F).Heat index
The heat index in October is appraised at a blistering 43°C (109.4°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.In reference to the heat index, it's for places in shade and with a slight wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 especially vital to children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
