Weather in September

The heat index value during September is evaluated at an extremely hot 105.8°F (41°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular 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.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
