November presents a welcome relief from the intense rains of
October in
Kingston. Even with a significant drop in rainfall to 65mm (2.56"), the humidity levels remain elevated, maintaining the tropical feel of the city. The sea temperatures remain warm, prevalent for water activities. Approaching
December, one can expect further reduction in rainfall along with a slight dip in temperature.
Temperature
Stepping into November, Kingston records an average high-temperature of a still tropical 31.2°C (88.2°F), almost consistent with October. Throughout the month of November, the nighttime temperature dips to an average of 22.8°C (73°F).
Heat index
For most parts of November, the heat index is evaluated at a blistering 40°C (104°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

UV index

Note: An average maximum UV index of 9 in November leads to these recommendations:
Precautions are essential; the risk of damage to unprotected skin and eyes is too high. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Apply generously and frequently a broad-spectrum SPF 30+ sunscreen every two hours, or immediately after swimming or any outdoor exercise. Note! Reflective surfaces like sand and water heighten the UV radiation levels.
