December ushers in a weather shift, with temperatures and humidity taking a slight dip from
November. Nonetheless, the rainfall persists in high amounts of 445mm (17.52"), winding down from the November peak. Sea temperature sees a decrease aligning with the cooler month. Notably, the length of daylight hours drops insignificantly, hinting at the close of the year. The December weather in
Songkhla primarily entails decreased temperatures and high rainfall, complemented by comfortably warm sea temperatures.
Temperature
December is the coldest month, exhibiting average temperatures of 29.2°C (84.6°F) at the peak and 24.4°C (75.9°F) at the base.
Heat index
For December, the heat index is calculated to be a very hot 36°C (96.8°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. 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 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
