June weather forecast
Xi'an, China

June marks the onset of summers in Xi'an and is characterized by high temperatures, reaching a peak of 31.2°C (88.2°F). This surge in temperature is significantly higher than May’s weather. It also records increased rainfall as compared to May, indicating an intensifying monsoon pattern. As days are filled with more sunshine and longer daylight hours, it is imperative to take preventive measures against high UV levels. June's balmy and rainy weather gives a foreshadowing of July's climatic conditions.

Temperature

June's arrival in Xi'an brings a change in high-temperatures, moving from a warm 26.1°C (79°F) in May to a hot 31.2°C (88.2°F). Xi'an documents a striking divergence from daytime highs, with an average nighttime temperature of 19.2°C (66.6°F) in June.

Heat index

In June, the average heat index is estimated at a sweltering 36°C (96.8°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

UV index

June and July, with an average maximum UV index of 11, are months with the highest UV index in Xi'an, China. A UV Index reading of 11, and higher, represents an extreme health hazard from unsafe exposure to UV radiation for average individuals.
Note: A maximum UV index of 11 in June translates into the following recommendations:
Take all required precautions, as unprotected skin and eyes can burn in minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Directly after swimming or an outdoor workout, generously apply and reapply a broad-spectrum SPF 30+ sunscreen.
