Weather in September
Temperature
Washington's weather, upon September's arrival, documents an average high-temperature of a warm 85.3°F (29.6°C), nearly identical to the prior month. Washington's temperature in September lowers to a consistent average of 65.3°F (18.5°C) during the nights.Heat index
In September, the heat index is appraised at a fiery hot 95°F (35°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
