Weather in September
Temperature
September is the month when Santa Cruz dos Milagres's temperatures reach their peak, with averages of 36.6°C (97.9°F) and lows of 23.5°C (74.3°F).Heat index
For September, the heat index is calculated to be a blisteringly hot 43°C (109.4°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. 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. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
