Weather in September
Temperature
August's transformation into September witnesses an average high-temperature of a still tropical 86.2°F (30.1°C), noting a minor change from the preceding month. During September, the nighttime temperature in Dickinson averages of 75.7°F (24.3°C).Heat index
September's heat index is estimated at a sweltering 98.6°F (37°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes. Forewarned is forearmed! The Sun's UV radiation can be almost doubled in intensity by snow reflection.
