September, the first month of the autumn in Cosme, is still a hot month, with temperature in the range of an average low of 74.8°F (23.8°C) and an average high of 88.7°F (31.5°C).

Temperature

The advent of September observes an average high-temperature of a still hot 88.7°F (31.5°C), nearly identical to August's 90.5°F (32.5°C). In September, Cosme experiences a temperature dip to an average of 74.8°F (23.8°C) at night.

Heat index

Throughout September, the heat index is evaluated at a blisteringly hot 105.8°F (41°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
