July takes the throne as the hottest and wettest month of the year in
Beijing. The maximum temperature peaks at 30.9°C (87.6°F), and the city receives the highest rainfall of 185mm (7.28") this month. The extreme weather does not deter the city’s life rhythm. Despite the intensity of the weather conditions, activities carry on, albeit with alterations to adapt to the climate. Interestingly, sunshine hours drop compared to
June, largely due to increased cloud cover.
Temperature
Temperature readings in Beijing reach their annual highs in July, averaging 30.9°C (87.6°F) and a minimum average of 22°C (71.6°F).
Heat index
In July, the average heat index is estimated at a fiery hot 39°C (102.2°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
Humidity
In Beijing, the average relative humidity in July is 75%.
Rainfall
July is the month with the most rainfall in Beijing,
China. Rain falls for 13.6 days and accumulates 185mm (7.28") of precipitation.
Daylight
In July, the average length of the day is 14h and 41min.
On the first day of the month, sunrise is at 04:49 and sunset at 19:46. On the last day of July, sunrise is at 05:12 and sunset at 19:29 CST.
Sunshine
In Beijing, the average sunshine in July is 6.9h.
UV index
June and July, with an average maximum UV index of 9, are months with the highest UV index in Beijing. A UV Index reading of 8 to 10 represents a very high health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: A daily high UV index of 9 in July leads to these guidelines:
Always prioritize safety measures. Rapid harm can befall unprotected skin and eyes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half. Even when the sky is cloudy, apply generously and frequently reapply a sunscreen with SPF 30 or more, especially post every swim or outdoor exercise.
