Weather in December
Temperature
With the transition into December, Jalbot notes an average high-temperature of a warm 28.8°C (83.8°F), closely resembling November. Jalbot's December nights exhibit a subtle drop in temperature, averaging at 24.5°C (76.1°F), closely aligned with the daytime highs.Heat index
The average heat index in December is computed to be a fiery hot 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Deflect overexposure. Sun protection is a necessity. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
