Weather in September
Temperature
In September, the average high-temperature registers at a still warm 29.2°C (84.6°F), nearly identical to August's 29.4°C (84.9°F). Constancia's September nights witness minimal differential from the daytime temperatures, with averages of 25.6°C (78.1°F).Heat index
The average heat index in September is evaluated at a very hot 35°C (95°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Consider that heat index readings are for situations in the shade and light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

A UV Index reading of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the ordinary person.Note: A maximum daily UV index of 7 during September morphs into the following directions:
Shield from overexposure. Defense against sun-related harm is required. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
