Weather in October
Temperature
A subtle change in temperatures is noted as September gives way to October, with average highs reducing from a tropical 86.9°F (30.5°C) to a moderately hot 80.8°F (27.1°C). October's nights observe an average temperature of 65.8°F (18.8°C).Heat index
The heat index for October is evaluated at 84.2°F (29°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
