Weather in September
Temperature
The ushering in of September brings an average high-temperature of a still moderately hot 29.5°C (85.1°F), closely mirroring the 29.3°C (84.7°F) of August. Angurukaramulla records a mild decrease in temperature during the nights of September, averaging a still warm 25.2°C (77.4°F).Heat index
The average heat index in September is computed to be a sweltering 36°C (96.8°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
