Weather in September
Temperature
The month of September, characterized by an average high of 29.7°C (85.5°F) and a low of 16.8°C (62.2°F), is recognized as the warmest.Heat index
For most parts of September, the heat index is calculated to be a hot 31°C (87.8°F). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
