Hallowe'en is this Sunday, and it is easily one of Canada's most weather-dependent holidays.
“Boy, there's a lot of pressure on forecasters for this particular occasion!” says David Phillips, senior climatologist with Environment Canada. “I can't imagine a day of the year where it's more important to get the forecast right!”
That's because there's no postponing Hallowe'en or moving it indoors. There's also a specific time of day (usually, trick-or-treating time) when parents need to know what the weather is going to be like.
Phillips says that can be tricky for forecasters, especially given the time of year.
“We do have a variety of weather including summer-like, winter-like, we do have wind and rain and snow. Almost anything that Mother Nature can throw at us in Canada can occur on October 31.”
And that can make picking costumes and dressing for the conditions a bit of a challenge.
“Children and parents often decide what they're going to wear based on the weather,” says Phillips. “That's why you have to almost kind of tell young people what the situation's going to be well in advance so that they can decide whether they're going to wear this or that, whether they'll be covered over.”
Pamela Fuselli is with Safe Kids Canada. She says it's important to make sure your children are dressed for the cooler weather.
“Make sure they're wearing something that will keep the heat against their body...like gloves,” says Fuselli.
In some parts of the country, you may want to keep your umbrella close by. Rain is forecast for Vancouver. “We have a large area of low pressure moving in to the B.C. coast,” says Michelle Cassar, a meteorologist at The Weather Network.
And it's unsettled in the Maritimes, with flurries expected in New Brunswick. “We're also looking at the potential for some on and off showers in Atlantic Canada,” says Cassar.
There is also a chance of snow in Ontario from Georgian Bay to Kitchener, says Patrick Cool, another meteorologist at The Weather Network. “It will be mostly dry across southern Ontario, except for the risk of a rain or snow shower in the snowbelt region,” he says.
In the Prairies, it is dry and temperatures are close to seasonal.
No matter what the weather is like, Phillips has this advice for parents:
“Parents should stay tuned to the forecast and get updates, and be able to be in a position to modify costumes and the routes that the children are going to take for Hallowe'en. It's very weather sensitive that day, and I think you can help the experience for young people by paying attention to the weather.”
