Weather in September
Temperature
Alaipur, Bangladesh, indicates an average high-temperature of a still hot 31.9°C (89.4°F) in September, showing minor variation from August's 32.3°C (90.1°F). Alaipur's nighttime temperature during September is consistently averaged at a warm 25.5°C (77.9°F).Heat index
The heat index in September is evaluated at a burning hot 45°C (113°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
