At this time, Shenzhen is in the main flood season. Due to the influence of marine air masses, southerly winds generally blow, rain is abundant, air humidity is high, and body temperature is high. It is the peak period of tropical cyclone influence. The main possible weather influences include tropical cyclones, Heavy rain, thunderstorm, high temperature, haze, etc. According to statistical analysis of relevant meteorological data, tropical cyclones, heavy rains, thunderstorms, high temperatures, and haze have a 100% probability of affecting the Universiade. Judging from historical statistics, at least one type of high-impact weather will appear during the Universiade. The Universiade may be the event most severely affected by meteorological factors among the domestic large-scale sports events in recent years, and the weather support service task is very arduous.

According to statistical probability, during the Universiade in Shenzhen, the whole city will be affected by a typhoon, with an average impact time of 2.9 days and a maximum of 7 days. The severe impact time is usually about 1 day, and the probability of rainfall is 59%. Typhoons may destroy some temporary buildings, facilities and sports equipment, and coastal competition venues are more threatened by typhoons. According to analysis, this year's weather and climate are relatively severe in disastrous weather. There will be 4 to 5 typhoons affecting Shenzhen this year, of which 1 to 2 will seriously affect Shenzhen. These 1 to 2 typhoons will be In July and August, although August is the stage where events are concentrated, July has already entered the stage of Universiade-related test matches and large-scale event rehearsals, so the challenge of the entire service is very severe.

The second is heavy rain. The average number of rainfall days in August over the past years is 18.3, and the average daily rainfall is above moderate rain. During the Shenzhen World Universiade, the daily rainfall probability is between 50% and 70%.

The average number of thunder and lightning days per month is 14.4 days, with a maximum of 24 days. The active period is from 14:00 to 16:00, which is the afternoon competition period of the Universiade. Some competition venues located in Bao'an, Nanshan, and Futian are in areas with relatively intensive lightning strikes, such as Guanlan Golf and Guanlan Country Club Tennis Center. The impact of lightning must be fully considered when arranging sporting events.

Continuously hot and muggy weather can easily lead to heatstroke. It can also affect the preservation of food and certain items, leading to mildew and rot.

The fifth is haze. There are an average of 4 haze days in August. In the early stage of the typhoon, the peripheral downdrafts are strong.
