March, the first month of the spring in
Roi Et, is also a hot month, with an average temperature varying between 22.7°C (72.9°F) and 34.7°C (94.5°F).
Temperature
March's advent notes a subtle adjustment in average high-temperature to a still tropical 34.7°C (94.5°F) from
February. Roi Et marks a considerable descent from the daytime apex, as the average temperature dips to a pleasant 22.7°C (72.9°F) at night throughout March.
Heat index
March's average heat index is appraised at a life-threatening hot 45°C (113°F).
Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Heat index values are typically calculated for conditions of shade and a light breeze. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 are particularly important for 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
Humidity
With an average relative humidity of 61%, March is the least humid month.
