Weather in September
Temperature
As Pekan Binjai steps into September, the average high-temperature is measured at a still hot 33°C (91.4°F), displaying minor differences from August's 33.5°C (92.3°F). September brings Pekan Binjai a consistent average low-temperature of 23°C (73.4°F).Heat index
The heat index value during September is evaluated at a burning hot 46°C (114.8°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Take into consideration that the heat index values are calculated for shade and light wind conditions. When under direct sunshine, the heat index may be elevated 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. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 remain especially vital for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
