September weather forecast
Rading, Bhutan

September in Rading, Bhutan, marks a gradual withdrawal of the monsoon, paving the way for the onset of autumn. The monsoon's receding phase is evident in the decrease in rainfall from the preceding few months. However, the earlier monsoon humidity holds relatively steady, contributing to a clammy feel in the otherwise cooling weather. By this time, the temperature progression leans towards a cooler bend, however, it remains temperatively pleasant. Altogether, September offers a respite from the heightened monsoon and ushers in the more comfortable autumn season.

Temperature

Heat index

September's heat index is computed to be an extremely hot 44°C (111.2°F). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Realize that the values for the heat index are set for shaded places and light winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
