Weather in October
Temperature
October denotes a minimal variation in the average high-temperature to a moderately hot 82.6°F (28.1°C) from September's 86.9°F (30.5°C). Siesta Key anticipates an average minimum temperature of 71.8°F (22.1°C) in the month of October.Heat index
For most parts of October, the heat index is evaluated at a hot 87.8°F (31°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
