Weather in October
Temperature
The advent of October sees the average high-temperature at a still tropical 32.3°C (90.1°F), subtly shifted from September's 32.2°C (90°F). In October, the average low-temperature in Petaling Jaya records at a warm 23.9°C (75°F) during the nights.Heat index
The heat index for October is estimated at a scorching 43°C (109.4°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.When assessing, remember that heat index measurements are for light winds and shaded spots. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
