Temperature

September's arrival registers an average high-temperature of a still hot 31.5°C (88.7°F), closely aligning with the temperature of the previous month. Chichigalpa, during September nights, observes an average temperature of 23.8°C (74.8°F).

Heat index

September's mean heat index is computed to be a blisteringly hot 43°C (109.4°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess 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. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
