Weather in May

May is the time when summer's grip firmly establishes itself over Lahan, Nepal, and its surroundings. The weather is characterized by some of the hottest days, with rainfall levels going up to 55mm (2.17"). Compared to April, clouds become more frequent, marking the start of the monsoon season. However, the amount of daylight and sunshine the city receives remains commendably high but starts to decline subtly. As always in this area, wind conditions remain within comfortable limits, thus posing little to no hindrance to the residents or the visitors.

Temperature

May temperatures tend to peak at an average high of 38.2°C (100.8°F) and dip to a low of 26.8°C (80.2°F).

Heat index

May's mean heat index is calculated to be a burning hot 45°C (113°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

UV index

April, May and August, with an average maximum UV index of 8, are months with the highest UV index. A UV Index reading of 8 to 10 represents a very high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: The UV index of 8 during May translates into the following guidance:
Skin and eyes are vulnerable without protection. Ensure you always take precautions. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
