Weather in September
Temperature
September's onset corresponds with a subtle shift in the average high-temperature, slightly moving from a hot 94.1°F (34.5°C) in August to a moderately hot 85.6°F (29.8°C). In the month of September, Bromide experiences an average low-temperature of 66.2°F (19°C).Heat index
In September, the heat index is computed to be a hot 93.2°F (34°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.The standards for the heat index are set for locations in shade and under light 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 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
