It's bad news for holiday makers in Thailand and those planning a trip there for the school holidays.
Ten popular beaches in Phuket have been closed due to heavy rainfall, strong winds and high tidal waves.
Red flags have been put up and signs in five different languages are on beaches telling people not to swim.
Thailand is currently in the monsoon season.
The 10 beaches impacted are Mai Khao, Nai Yang, Nai Thon, Bang, Surin, Kamala, Patong, Karon, Kata and Nai Han.
