Weather in September
Temperature
Bendiyamulla's weather in September displays an average high-temperature of a still warm 29.5°C (85.1°F), showing minor disparity from August's 29.3°C (84.7°F). A mean low-temperature of 25.2°C (77.4°F) is anticipated during the month of September, a slight step down from the daytime high.Heat index
In September, the average heat index is estimated at a sweltering 36°C (96.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
