Weather in September
Temperature
Intipucá marks the onset of September with an average high-temperature of a still tropical 31.8°C (89.2°F), subtly divergent from August's 32.8°C (91°F). In the month of September, an average of 23.5°C (74.3°F) marks the low-temperature.Heat index
In September, the heat index is appraised at a scorching 43°C (109.4°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
