Weather in September
Temperature
The onset of September is marked by a minor decrease in temperature, transitioning from a hot 89.6°F (32°C) in August to a warm 83.8°F (28.8°C). Hermanas records an average nighttime low-temperature of 65.5°F (18.6°C) throughout September.Heat index
For September, the heat index is estimated at 84.2°F (29°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
