Weather in September
Temperature
The arrival of September signals a subtle shift in temperature, down from a sweltering 95.5°F (35.3°C) in August to a hot 87.6°F (30.9°C). An average temperature of 69.8°F (21°C) is recorded during the nights in September.Heat index
The heat index value during September is computed to be a torrid 96.8°F (36°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
