Weather in August
Temperature
The commencement of August introduces an average high-temperature of a still hot 86.5°F (30.3°C), closely mirroring the preceding month. During the month of August, Jamaica experiences a steady low-temperature average of 68.4°F (20.2°C).Heat index
The heat index value for August is estimated at a very hot 98.6°F (37°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' 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. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
