Weather in September
Temperature
The advent of September denotes an average high-temperature of a still tropical 33.1°C (91.6°F), subtly different from August's 32.3°C (90.1°F). In the month of September, the temperature in Giriftu generally rests at an average low of 22.9°C (73.2°F).Heat index
The heat index in September is evaluated at a torrid 37°C (98.6°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Realize that the values for the heat index are set for shaded places and light 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 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Rising body temperatures due to excess heat retention could signify impending heat disorders.
