October is identified as
Kingston's wettest month with rainfall peaking to 6.97" (177mm). This spike in rainfall does not drastically affect temperature trends which hover around their annual highs. Sea temperatures are slightly lower than in
September; however, they still offer conducive conditions for water activities. As the year progresses into
November, a gradual decrease in rainfall can be anticipated.
Temperature
The average high-temperature during October is a still tropical 89.1°F (31.7°C), almost matching the conditions of the preceding month. In the month of October, Kingston records a consistent average low-temperature of 74.1°F (23.4°C).
Heat index
The heat index for October is evaluated at a blisteringly hot 109.4°F (43°C).
Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.
Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 particularly meaningful for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Always safeguard yourself; without protection, skin and eyes can get damaged instantly. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses. Sunscreen with a sun protection factor of no less than 30 should be used liberally and reapplied frequently on overcast days, including after every swim or outdoor activity. Notice! The reflection of water and sand increases the UV radiation significantly.
