Weather in September

The heat index value during September is calculated to be a very hot 38°C (100.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Always consider that heat index estimations are for light winds and places in the shade. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
