Metro Vancouver’s Halloween forecast: Ghosts, princesses, goblins will face a chance of showers

Metro Vancouver’s Halloween forecast is shaping up to be a bit of a trick-or-treat, with a chance of showers as little ghosts, goblins and superheroes prepare to hit the streets Saturday night.

A cold upper low system is expected to move through the region on Saturday, bringing the possibility of showers during the day and in the evening, said Environment Canada.

“There’s some remnant instability on the tail end of it,” said meteorologist Gary Lee. “Over the North Shore mountains, there’s a higher chance of showers, and there’s a little less of a chance away from them.”

The forecast is looking less spooky, however, as the region emerges from a wet week, offering trick-or-treaters hope they won’t have to lug an umbrella along with their candy bags.

The system, which arrived Tuesday night and is expected to linger off the Washington state coast, is contributing to unsettled weather in the Pacific Northwest, including the Lower Mainland, with rain or showers forecast across the region from Wednesday to Friday.

Little monsters heading out for candy should consider bundling up, with temperatures expected to dip to single digits — at around 8 or 9 C — on Halloween night.

The Weather Network is offering a more optimistic outlook on Halloween night, calling for sun during the day, followed by a partly cloudy evening with a low chance of showers.

Historically, Halloween has been more trick than treat when it comes to the weather, with rain more likely than dry skies.

Over the last century, rain has fallen on 61 Halloweens, including last year when trick-or-treaters were soaked by nearly 19 millimetres of rain recorded at the Vancouver airport.
