August weather forecast
Kathmandu, Nepal

August ushers in a slight reprieve from the persistent monsoons, as rainfall begins to fade away gradually. The month remains warm, with no drastic changes in temperature from July. Longer daylight hours and decreased rainfall encourage more outdoor exploration. Moving into September, one can visibly see a decrease in rainfall, hinting towards the end of the monsoons. While the weather may still be wet, the beauty of glistening cityscapes after a bout of rain is unmatched.

Temperature

Kathmandu, Nepal, measures an average high-temperature of a still moderately hot 28.7°C (83.7°F) in August, nearly consistent with the preceding month. Kathmandu reports a consistent average low-temperature of 20°C (68°F) throughout August nights.

Heat index

During August, the heat index is estimated at a very hot 35°C (95°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

In August, the average relative humidity in Kathmandu is 83%.

UV index

April through August, with an average maximum UV index of 12, are months with the highest UV index in Kathmandu. A UV Index estimate of 11, and higher, represents an excessive health risk from unsafe exposure to UV radiation for ordinary individuals.
Note: In August, the maximum UV index of 12 suggests this advice:
Implement every essential safety step. Individuals with fair skin might receive burns in less than 5 minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. To protect your skin and immune system, apply a sunscreen of 30 SPF or higher. This prevents sunburn and damage from the Sun's rays.
