The stake of summer further amplifies in
April as the city experiences the highest temperature levels of the year, reaching a high of 35.9°C (96.6°F). Moreover, a sudden surge in rainfall, up from 33mm (1.3") to 100mm (3.94"), points towards an abrupt rainfall increase. Thus, the notion of "April showers" rings especially true in
Loei. Notably, the city plays host to the significant national water festival, known as the Songkran, which converges perfectly with the rising temperature and heightened rainfall. Elongated daylight hours enhance the opportunity for daytime activities despite the intense heat.
Temperature
Temperature records in Loei mark April as the warmest month, with highs averaging 35.9°C (96.6°F) and lows at 22.7°C (72.9°F).
Heat index
The heat index value for April is estimated at a blazing hot 52°C (125.6°F).
Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
