Weather in September
Temperature
The onset of September marks an average high-temperature of a still moderately hot 28.7°C (83.7°F), hardly differing from August's 29.4°C (84.9°F). A steady low-temperature average of 27.3°C (81.1°F) is logged during September, reflecting a modest dip from daytime readings.Heat index
The heat index in September is calculated to be a tropical 34°C (93.2°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
