Weather in October
Temperature
The arrival of October suggests a slight decrease in the average high-temperature, moving from a hot 92.5°F (33.6°C) in September to a warm 85.6°F (29.8°C). An average low-temperature of 68.2°F (20.1°C) marks the nights throughout October.Heat index
The heat index in October is appraised at a tropical 89.6°F (32°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
