Weather in September
Temperature
The transition from August to September sees average high-temperatures adjusting to a still tropical 32.4°C (90.3°F), from a not significantly different 32.6°C (90.7°F). Throughout the nights in September, Nandibari experiences an average low-temperature of 25.7°C (78.3°F).Heat index
The heat index value during September is evaluated at a burning hot 46°C (114.8°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Note that heat index values are valued for light wind and location in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 extremely significant for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
