In
June,
Yan'an truly embraces summer, as temperatures soar to 28.7°C (83.7°F). The long sunny days, accompanied by increased humidity, define the weather trends in the city during this month. Despite the rising temperature, the rainfall levels also increase considerably, resulting in occasional showers which provide a much-needed respite from the heat.
Temperature
Yan'an in June observes a minor temperature shift, with average high-temperatures adjusting from a warm 25.3°C (77.5°F) in
May to a still moderately hot 28.7°C (83.7°F). The June nights bear witness to a significant drop from the daytime highs, settling at an average temperature of 14.9°C (58.8°F).
Heat index
The average heat index in June is evaluated at a tropical 30°C (86°F). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Humidity
The average relative humidity in June is 59%.
