Weather in October
Temperature
The transition from September to October brings an average high-temperature of a still warm 27.6°C (81.7°F), barely different from September's 25.6°C (78.1°F). An average low-temperature of 18°C (64.4°F) is observed during October nights.Heat index
In October, the average heat index is evaluated at a tropical 31°C (87.8°F). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
