Weather in December

Satun introduces December as the official commencement of the dry season. A decrease in both temperature and rainfall distinctly sets this month apart from month-long monsoon stricken periods. Correspondingly, daylight experiences a curtailed hour, further enhancing the cool narrative of the season. In quantifiable terms, December serves as the driest month of the year, with scarce rainfall of 97mm (3.82"), and weather conditions fluctuating from 23.4°C (74.1°F) to 31.5°C (88.7°F), thereafter marking a noticeable transition towards drier days.

Temperature

Satun signifies an average high-temperature of a still tropical 31.5°C (88.7°F) in December, closely mirroring the 31.6°C (88.9°F) of November. Satun's nighttime temperature during December is consistently averaged at a moderately hot 23.4°C (74.1°F).

Heat index

The heat index for December is estimated at a blistering 41°C (105.8°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. 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 'real feel', reflects the feeling of heat when considering both air temperature and humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 of high significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

In December, the average relative humidity is 76%.
