Weather in September
Temperature
The commencement of September brings an average high-temperature of a warm 82.8°F (28.2°C), marking an inconsequential divergence from August. An average low-temperature of 63.3°F (17.4°C) is observed during the September nights.Heat index
The average heat index in September is computed to be a hot 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
