Many celebrities carried umbrellas as they walked the red carpet at the Beverly Hilton in Los Angeles ahead of the 67th annual ceremony.
Speaking to Entertainment Tonight, Clooney joked: "It's funny when it rains in LA, everybody falls apart!"
Taylor Lautner added: "This is my first Golden Globes, it's really exciting... I'm fine, I'm just excited to be here so I'm not complaining!"
Precious star Mo'Nique, who scooped the 'Best Supporting Actress - Drama' gong, said: "I have to give a lot of credit to my hairstylist because she came up with the perfect hairstyle, so any kind of weather baby, it will still be fabulous! It won't move. I could jump in a pool right now!"
Other stars to joke about the weather included Mariah Carey, who said that her hairstyle was "supposed to be rain-proof", and Robert Downey Jr, who suggested that the rain was Sir Arthur Conan Doyle "letting us know his presence here".
Tina Fey added to Billy Bush on NBC's pre-show: "It's not rain, it's just God crying for NBC!"
