Weather in December

Balboa, Panama, welcomes the year-end with December weather featuring reduced rainfall, marking the definitive end of the rainy season. With temperatures showing little variation from November, hovering around 28.8°C (83.8°F), the warm atmosphere remains. Despite the decline in rainfall, humidity levels stay high, paving the way for a tropical Christmas season in the city. Wind speeds escalate, lending to cooler evenings. All in all, December's weather profile is a mix of tropical warmth, reasonable rainfall, and manageable wind, summing up the Balboa's climate cycle for the year.

Temperature

Balboa's average high-temperature in December sits at a still warm 28.8°C (83.8°F), showing little difference from the previous month. The December nights show a slight decrease to a mean low-temperature of 24°C (75.2°F).

Heat index

December's mean heat index is calculated to be a fiery hot 35°C (95°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In December, the average relative humidity is 85%.

Rainfall

The months with the lowest UV index are January through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for average individuals.
Note: A daily high UV index of 7 in December leads to these guidelines:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
