Weather in September
Temperature
September's arrival brings an average high-temperature of a still hot 31.6°C (88.9°F), demonstrating subtle variation from the preceding month. Lunas registers a consistent average low-temperature of 23.5°C (74.3°F) during September.Heat index
September's mean heat index is evaluated at a scorching 42°C (107.6°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high 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 human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
