When Is the Typhoon Season in Shenzhen? How Many Typhoons Affect It Each Year?

Shenzhen’s Typhoon Season: Time Window and Peak Period
Shenzhen lies on the northern coast of the South China Sea and is significantly affected by tropical cyclones from the northwestern Pacific and South China Sea. According to climatological statistics, typhoons can form throughout the year, but the “typhoon season” in Shenzhen—meaning the period when typhoons produce substantial effects on wind and rainfall—is concentrated in June through October. Among these months, July, August, and September form the “core peak period,” when typhoon impacts are most frequent and often most intense.
The characteristics of each month are as follows:
- May: Early-season typhoon disturbances occasionally occur, but the probability is relatively low.
- June: The monsoon trough becomes active, and the frequency of typhoon formation gradually rises.
- July to September: Sea surface temperatures are high and atmospheric energy is abundant, making strong typhoons or super typhoons more likely and posing the highest disaster risk.
- October: Although the frequency of impacts is declining, vigilance is still needed for “autumn typhoons,” whose tracks can be complex and which often combine with cold air to bring intense rainfall.
- November to the following April: Direct impacts from typhoons are extremely rare.
A special point to note is that typhoons forming locally in the South China Sea tend to develop and make landfall quickly. It may take only 24–48 hours from formation to coastal impacts, so vigilance must never be relaxed, even outside the peak period.
Average Annual Number of Impacts and the Definition of “Impact”
According to long-term meteorological records, Shenzhen is affected by an average of 2 to 4 typhoons per year. The concepts of “impact” and “landfall” must be clearly distinguished:
- Impact: This means that the typhoon’s center passes near Shenzhen, or that its outer circulation (spiral rainbands) brings strong winds and heavy rainfall to the city. Even if a typhoon makes landfall in Zhanjiang, Hainan, Fujian, or Vietnam, Shenzhen may still experience severe wind and rain when the storm enters the warning area.
- Year-to-year variability: Typhoon activity varies significantly from year to year. It is influenced by climate factors such as the position of the subtropical high and El Niño/La Niña conditions. In some years, Shenzhen may be affected by more than five typhoons, while in others it may experience only one or even no significant impacts.
Interpreting Warning Signals and Defensive Action Guide
China uses four levels of typhoon warning—blue, yellow, orange, and red—with darker colors indicating greater danger. Shenzhen strictly implements the Meteorological Disaster Prevention Regulations of Guangdong Province. Different warning levels correspond to different public response measures, with specific implementation standards based on the latest announcements from local government and education authorities:
- Blue/Yellow warning: Preparations for defensive action are required. While a yellow warning is in effect, nurseries, kindergartens, primary schools, and secondary schools are normally automatically suspended, and parents should ensure that students remain safe.
- Orange/Red warning: Emergency defensive measures are required. While a red warning is in effect, employers may arrange work stoppages except for essential positions, and the public should remain indoors in safe locations.
Practical disaster-preparedness checklist:
- Before the event: Reinforce doors and windows; remove flowerpots and other objects from balconies to prevent them from falling from height; stock up on at least three days’ worth of drinking water, convenience food, common medicines, and fully charged power banks.
- During the event: Closely monitor the latest track and wind and rainfall forecasts issued by the meteorological authorities; avoid going outdoors and stay away from billboards, large trees, temporary structures, and low-lying coastal areas; if water enters your home, immediately cut off the electricity.
- After the event: Confirm that the surrounding area is safe before going out, and remain alert to secondary hazards such as landslides and electric shock caused by accumulated water.
