Weather in September
Temperature
Shifting into September, Hyco records an average high-temperature of a warm 83.3°F (28.5°C), presenting minor fluctuations compared to the previous month. September's average low-temperature reading settles at a comfortable 66.2°F (19°C).Heat index
The heat index value during September is estimated at a tropical 89.6°F (32°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
