Weather in October
Temperature
October is marked by a subtle drop in average high-temperatures, transitioning from a tropical 88.3°F (31.3°C) in September to a moderately hot 81°F (27.2°C). Houston encounters a steady low-temperature average of 64.2°F (17.9°C) throughout the month of October.Heat index
Throughout October, the heat index is evaluated at 84.2°F (29°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
