Weather in September
Temperature
The shift into September records an average high-temperature of a still tropical 32°C (89.6°F), subtly varied from August's 33.1°C (91.6°F). An average low-temperature of 22.7°C (72.9°F) is anticipated throughout the nights during September.Heat index
September's mean heat index is estimated at a blisteringly hot 42°C (107.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
