Hide AdThe gala marks the beginning of the Leith Festival, which will run until June 19, and organisers and residents attending said the rain did not spoil people's enjoyment of the event.
Michael Scott, 24, a plumber from Leith, took his visiting nephews to the gala.
He said: "When we woke up and saw the rain we did consider doing something else.
"But I'm glad we stuck with it. It's a great community occasion and a lot of work goes into the organising of it."
Among the organisations at the gala day were the Scottish Lime Centre, local churches and the Leith Historical Society.
