September

Weather in September

September, the first month of the autumn in Lapangan, is still a hot month, with an average temperature ranging between min 24°C (75.2°F) and max 30.4°C (86.7°F).

Temperature

The transition from August to September brings an average high-temperature of a still hot 30.4°C (86.7°F), barely different from August's 30.2°C (86.4°F). Lapangan anticipates an average minimum temperature of 24°C (75.2°F) in the month of September.

Heat index

September's heat index is computed to be a very hot 38°C (100.4°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are largely significant for babies and toddlers. 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, as evaporated sweat carries heat away from the body. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
