Weather in September
Temperature
The average high-temperature in September, at a still hot 86°F (30°C), reveals a modest deviation from August's 90.1°F (32.3°C). The temperature lowers to an average of 66.7°F (19.3°C) during September nights.Heat index
For most parts of September, the heat index is calculated to be a torrid 96.8°F (36°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 are primarily vital for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
