Weather in September
Temperature
September's weather displays an average high-temperature of a warm 85.8°F (29.9°C), slightly varied from August's 88.7°F (31.5°C). In Montrose, the September nights cool down to an average low of 74.5°F (23.6°C).Heat index
Throughout September, the heat index is computed to be a sweltering 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Factoring in the heat index, values are geared towards shaded areas with light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
