Weather in October
Temperature
An average high-temperature of a still hot 32.7°C (90.9°F) marks October, exhibiting a close resemblance to the conditions in September. In October, the temperature drops to an average of 23.2°C (73.8°F) at night.Heat index
Throughout October, the heat index is evaluated at a life-threatening hot 45°C (113°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight might lead to a heat index increase by up to 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. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
