Weather in September
Temperature
With the arrival of September, Pendleton experiences a modest decline in average high-temperatures, transitioning from a tropical 88.3°F (31.3°C) in August to a warm 82.8°F (28.2°C). Pendleton experiences a consistent average temperature of 63°F (17.2°C) throughout the nights in September.Heat index
The heat index value for September is calculated to be a hot 87.8°F (31°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
