Weather in September
Temperature
Metmárfag's shift into September is marked by a subtle change to a moderately hot 28.5°C (83.3°F) from August's 30.5°C (86.9°F) in temperature. An average low-temperature of 20.9°C (69.6°F) marks the month of September.Heat index
The average heat index in September is computed to be a hot 31°C (87.8°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
