Maha Sarakham, is still a tropical month, with an average temperature fluctuating between 16.7°C (62.1°F) and 30.5°C (86.9°F).
Temperature
Temperature readings reach their annual highs in December, averaging 30.5°C (86.9°F) and a minimum average of 16.7°C (62.1°F).
Heat index
December's average heat index is appraised at a fiery hot 36°C (96.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.
Humidity
In December, the average relative humidity is 70%.
