Unión Oriental, Ecuador

Temperature

The introduction of December sees an average high-temperature of a still hot 30.2°C (86.4°F), hardly deviating from November. An average low-temperature of 19.5°C (67.1°F) is common during the nights of December.

Heat index

December's average heat index is estimated at a sweltering 39°C (102.2°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. 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. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Humidity

In December, the average relative humidity is 82%.

Rainfall

In December, the rain falls for 27.4 days. Throughout December, 177mm (6.97") of precipitation is accumulated. Throughout the year, there are 310.3 rainfall days, and 2604mm (102.52") of precipitation is accumulated.

UV index

The months with the highest UV index are January, February, May, July through December, with an average maximum UV index of 6. A UV Index value of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for ordinary individuals.
Note: The daily high UV index of 6 during December translates into the following recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
