"It could have gone ahead but it would have been pretty miserable out there," Mr Mooney said.
Instead, the participants were hosted at the Art Deco Centre for a cup of tea, some snacks and a quiz, which was staged in the cinema room.
"Everything else has run just fine," Mr Mooney said.
The main open-air event of the weekend, Saturday's Costumes and Cars in Emerson St, went off without a hitch as the weather stayed fine. A good-sized crowd applauded the fine fashion as couples taking part in the Best Dressed competition walked gracefully by.
Overall numbers were up on last year and Mrs Jackson said the signs were all there that the mid-winter Deco event would become more popular.
"We have some people telling us they prefer to come to this one because there aren't the big crowds you get at the summer event."
Nearly a third of those who bought tickets for events were from out of town.
"So it's a bit of a mid-winter boost for the local economy."
With a smile, Mr Mooney said the RM31 railcar event Dinner on the Run had almost certainly created a world record.
He doubted anywhere else in the world had put on a progressive meal outing centred on a railcar.
It started with a drink and nibbles at the Munro St station, stopped for dinner at the Thirsty Whale, then resumed when a dessert and warming drink was served on board.
"Let's get on to the Guinness people," he said, with a smile.
