Weather in September
Temperature
Entering September, the average high-temperature is recorded at a still tropical 31.8°C (89.2°F), exhibiting a minimal shift from August's 30.8°C (87.4°F). Banjarkemantren's temperature lowers to a mean of 24.5°C (76.1°F) during the nights in September.Heat index
The average heat index in September is estimated at a fiery hot 38°C (100.4°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
