Weather in September

September ushers in an average high-temperature of a warm 82.6°F (28.1°C), aligning closely with the preceding month. In Mount Croghan, an average temperature of 65.1°F (18.4°C) is noted during September nights.Heat index
For most parts of September, the heat index is estimated at a tropical 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
