December weather forecast
Pilar, Paraguay

As the final month of the year, December brings forth peak summer patterns with a simultaneous rise in temperatures, creating a distinct climatic scenario in Pilar, Paraguay. Maximum temperatures close to 32.8°C (91°F) underline the prevalent heat intensity while a corresponding drop to 21.3°C (70.3°F) at night provides some relief. A higher UV index of 7 in coincidence with a decreasing number of rainfall days illustrates classic summer weather patterns. Despite the increasing heat, recurrent wind gusts of 15.8km/h (9.8mph) help maintain a semi-comfortable atmosphere. With high humidity and a significant percentage of cloud cover, December ends with a mixed bag of weather constituting warm days and cooler nights, bringing the year to a close.

Pilar's weather in December displays an average high-temperature of a still tropical 32.8°C (91°F), showing minor disparity from November's 30.7°C (87.3°F). In Pilar, the expected average low-temperature for December is an agreeable 21.3°C (70.3°F).

Heat index

The heat index value during December is calculated to be an extremely hot 42°C (107.6°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
