May enters with a continuation of high-temperature trends but at a slightly subdued level compared to
April, indicating the beginning of a gradual cooling course. However, the significant factor in May is the substantial increase in rainfall, reaching an impressive 177mm (6.97"), rendering it the month of heavy showers in
Loei. Humidity, along with intermittent rain episodes, makes the atmosphere heavy and moisture-laden. Despite the daytime heat, the nights turn pleasantly cool, bridging the transition between day and night. Therefore, the weather emphasizes the coexistence of heat and showers in this summer month.
Temperature
May's advent presents an average high-temperature of a hot 33.8°C (92.8°F), indicating a slight variation from the conditions of the previous month. Loei, in the month of May, anticipates a consistent average low-temperature of 23.7°C (74.7°F).
Heat index
May's heat index is estimated at a blazing hot 50°C (122°F).
Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
