Weather in September
Temperature
September ushers in a minor alteration in Valley View's climate, with the average high-temperature moving from August's fiery hot 95.2°F (35.1°C) to a hot 86.7°F (30.4°C). In Valley View, the expected average low-temperature for September is an agreeable 68.9°F (20.5°C).Heat index
For September, the heat index is calculated to be a sweltering 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
