Weather in August

August brings continuity to the monsoon season in Janakpur, Nepal, with 161mm (6.34") of rainfall spread across the month. While moving slightly downwards from July, the weather is still dominated by frequent and abundant rain showers. The persistence of hefty showers affects the weather making the environment slick with moisture. Amid the high humidity, temperatures start to show a mild dip, signaling a slow march towards the end of the broiling summer. Thus, August is typically a transition phase from the heavy monsoon towards the forthcoming autumn season.

Temperature

August's average high-temperature is a still tropical 34.2°C (93.6°F), maintaining a close comparison with July's 34.3°C (93.7°F). Throughout the month of August, Janakpur expects an average low of 26.8°C (80.2°F).

Heat index

The heat index value during August is computed to be a blazing hot 48°C (118.4°F). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
