Weather in September

September, the first month of the autumn in Melrose, is still a hot month, with an average temperature varying between 88.2°F (31.2°C) and 72.3°F (22.4°C).

Temperature

September's onset brings an average high-temperature of a still hot 88.2°F (31.2°C), showing a minute difference from August's 90.9°F (32.7°C). An average low-temperature of 72.3°F (22.4°C) is anticipated throughout the nights during September.

Heat index

In September, the average heat index is evaluated at an extremely hot 105.8°F (41°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. 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 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
