August brings minimal change to the established weather pattern in
Kingston. The sea temperatures reach the year's peak at 29.4°C (84.9°F), offering perfect conditions for sea lovers. Even though temperatures remain consistently high, August marks a comeback for extensive rainy periods. Moving into
September, both rainfall and relative humidity are expected to rise.
Temperature
The ushering in of August brings an average high-temperature of a still tropical 32.7°C (90.9°F), closely mirroring the 32.8°C (91°F) of
July. Kingston experiences a mean low-temperature of 24.2°C (75.6°F) during August.
Heat index
The heat index value during August is evaluated at a blistering 44°C (111.2°F).
Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Employ every precaution of importance, unprotected skin and eyes could burn within moments. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Use liberally and reapply a broad-spectrum sunscreen with at least SPF 30 every two hours and right after outdoor activities or a swim. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
