Guangxi is located in the subtropical zone, which belongs to the monsoon climate. The rainfall is unevenly distributed. Rainy summer and floods occur frequently.

The existing dike is over 2,600 km long, of which the seawall is 890 km long and flood control standards reach 50 years In case of encounter with 20 years, the only difference is 57km and 350km respectively.
