Weather in October
Temperature
The warmest period is October, when temperatures fluctuate between an average high of 34.9°C (94.8°F) and a low of 20.8°C (69.4°F).Heat index
For most parts of October, the heat index is computed to be a burning hot 51°C (123.8°F). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
