Weather in September
Temperature
The shift into September records an average high-temperature of a warm 81.9°F (27.7°C), subtly varied from August's 86.9°F (30.5°C). In September, the nighttime temperature lowers to an average of 62.4°F (16.9°C).Heat index
September's heat index is evaluated at a hot 86°F (30°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Know that the heat index computations account for shaded terrains and slight winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
