Weather in September
Temperature
Rena Lara notes an average high-temperature of a warm 84.7°F (29.3°C) in September, displaying minor variation from August. An average low-temperature of 66.7°F (19.3°C) is observed during the September nights.Heat index
The heat index in September is calculated to be a hot 93.2°F (34°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 of high significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
