Weather in September
Temperature
With the advent of September, Kalbay experiences an average high-temperature of a still moderately hot 27.5°C (81.5°F), mirroring a close resemblance to the previous month. With a barely noticeable fluctuation in temperature, Kalbay reaches an average low of 23.5°C (74.3°F) during the September nights.Heat index
September's average heat index is estimated at a tropical 31°C (87.8°F). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
