Weather in September
Temperature
The onset of September brings with it an average high-temperature of a still moderately hot 28.1°C (82.6°F), showing a negligible variation from the month before. During September, Yelkakrom's nighttime temperatures demonstrate a subtle cooling from daytime highs, stabilizing at a still moderately hot 24.4°C (75.9°F).Heat index
September's average heat index is appraised at a hot 33°C (91.4°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Taking into account that direct sunlight can boost the heat effect, the heat index may rise 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.
