Floats are being prepared, dancers are rehearsing and everybody is hoping for a sunny bank holiday weekend - that's right, it can only be Notting Hill Carnival .
London's Afro-Caribbean communities have been celebrating their culture and traditions with the two-day festival since 1964.
Around 500 people came then, and now around one million people attend the carnival annually, with the event getting bigger and better every year.
This year, the carnival will take place over the August bank holiday weekend; Sunday August 28 to Monday August 29.
What's going on and when
Sunday August 28: From 6am to 9am there will be a Jouert, with African drums and steel bands.
Then, from 10am to 8.30pm there will be a children's day with a parade, calypso and soca music, food, performances and more.
Monday August 29: From 10am to 8.30pm there will be the finale and Monday parade, as 60 bands and 38 sound-systems rock Notting Hill and the surrounding areas.
