Weather in September
Temperature
Start of September brings a slight shift in the average high-temperature, dipping a bit from August's hot 91.2°F (32.9°C) to a moderately hot 85.8°F (29.9°C). Throughout September, San Carlos encounters an average temperature drop to an enjoyable 66°F (18.9°C).Heat index
The heat index in September is calculated to be a tropical 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
