Weather in September
Temperature
Montrose marks the start of September with an average high-temperature of a moderately hot 85.1°F (29.5°C), hinting at a slight fluctuation from August's 89.6°F (32°C). Montrose registers a consistent average low-temperature of 67.5°F (19.7°C) during September.Heat index
During September, the heat index is evaluated at a fiery hot 95°F (35°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
