Temperature
The shift into September reveals an average high-temperature of a tropical 34.8°C (94.6°F), closely mirroring August's climate. Throughout September nights, Sunam registers an average low-temperature of 23.9°C (75°F).Heat index
September's heat index is appraised at an extremely hot 44°C (111.2°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.Understand that the heat index values take into account shaded locations and mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
