Summer 2016 has alternated between wet and dry months.

It's been a soggy August in Dawson Creek, with the city receiving double its average rainfall for the month.

Dawson Creek recorded 108 mm of precipitation in August—with just under half of that falling during a rainstorm on Aug. 27. Between 1981 and 2010, the city has averaged 54 mm of rainfall that month, Environment Canada Meteorologist Ross Macdonald said.

"September 1 is typically the start of 'meteorological fall' but you guys seem to have been in it for a little bit longer," he said. "It's been unrelenting at times."

Summer 2016 has alternated between wet and dry months, according to Environment Canada data.  More than 168 mm fell at the city's weather station in June (up from an average of 67.4 mm for the month), followed by a drier than average July.

Fort St. John, meanwhile, saw 107 mm of rain in August, up from an average of 51 mm.

Macdonald said a slow-moving wet system out of the north is responsible for the damp conditions last month.  

"It was a system that took its time to move out of there. That's part of the trouble—these things hand around and it rains and it rains and it rains," he said.

That's in contrast to the rain system that caused widespread flooding in Dawson Creek in mid-June, which came out of the south.

"You usually get a bit more moisture out of (southernly systems). This particular flow was coming out of the north, so although it was a significant rain event, it wasn't as high as what you saw in the spring there."
