Weather in September
Temperature
September notes an average high-temperature of a still warm 29.3°C (84.7°F), subtly differing from August's 28.8°C (83.8°F). In Purwokerto, the average nighttime temperature during September is a pleasant 21.2°C (70.2°F).Heat index
In September, the average heat index is evaluated at a fiery hot 35°C (95°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
