Temperature

Jangli's weather in September displays an average high-temperature of a still hot 33.3°C (91.9°F), showing minor disparity from August's 32.3°C (90.1°F). During September, the average low-temperature is recorded at a moderately hot 23.9°C (75°F).

Heat index

Throughout September, the heat index is estimated at a blisteringly hot 43°C (109.4°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Take into consideration that the heat index values are calculated for shade and light wind conditions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

September is the least humid month, with an average relative humidity of 66%.

Prevent overexposure. Protection from the sun's harmful effects is needed. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
