Weather in October
Temperature
The move into October indicates a slight reduction in the average high-temperature, down from September's hot 90.3°F (32.4°C) to a moderately hot 84°F (28.9°C). An average temperature of 68.5°F (20.3°C) marks the nights in October.Heat index
During October, the heat index is estimated at a tropical 89.6°F (32°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Know that the heat index computations account for shaded terrains and slight winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
