Weather in September

September, the first month of the autumn in McCall, is still a hot month, with an average temperature ranging between max 87.3°F (30.7°C) and min 70.5°F (21.4°C).

Temperature

The transition into September marks the average high-temperature at a still hot 87.3°F (30.7°C), differing minimally from August's 90.1°F (32.3°C). Throughout the month of September, McCall reports a steady low-temperature average of 70.5°F (21.4°C).

Heat index

The average heat index in September is evaluated at a blistering 104°F (40°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. 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. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
