Weather in January

January through March bring Jacmel's lowest average temperatures, reaching a high of 27.2°C (81°F).Heat index
In January, the heat index is computed to be 29°C (84.2°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
