The arrival of December coincides with an average high-temperature of a hot 33.1°C (91.6°F), indicating a minimal shift from November's 35°C (95°F). Peritoró's temperature drops to an average low of 23°C (73.4°F) during the nights of December.

Heat index

Throughout December, the heat index is computed to be a blazing hot 46°C (114.8°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. 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 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Humidity

The average relative humidity in December is 75%.

UV index

The months with the lowest UV index are February through June and December, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for ordinary individuals.
Note: In December, a daily maximum UV index of 6 leads to the following instructions:
Deter overexposure. Protecting against the sun's effects is essential. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
