Metro Vancouver should have above-average precipitation over the summer with slightly warmer than usual temperatures.
Environment Canada meteorologist Chris Doyle said the summer, which the department measures from June 1 through Aug. 31, looks like it will be warmer overall but the signal for a "wetter" season is even stronger.
"Usually it isn't like that," he told V.I.A., highlighting how precipitation forecasts typically have less confidence than ones predicting temperatures.
"For June, at least, we are looking a little bit wetter-but we had a fairly wet start. The wet weather could have come already," he said.
Monday's (June 3) forecast for Vancouver includes showery weather through the day and overnight into Tuesday but the rain is expected to ease Tuesday afternoon.
Following June's wet start, a drier trend should commence Wednesday with temperatures climbing daily until Friday with a high of 23 C expected at V.I.A.'s Downtown Centre Weatherhood station.
June is also expected to include slightly warmer-than-average temperatures but the signal isn't as strong, added Doyle.
Metro Vancouver's weather forecast is similar to the rest of Canada for temperatures
Environment Canada expects nearly all of Canada will see temperatures a bit warmer than average over the summer except for Vancouver Island.
Doyle said a line lying through the inner south coast illustrates the divide between the mainland, which should see warmer weather, and the island, which is expected to see temperatures trending below average.
But the forecast could evolve heading further into the summer.
"There is a strong anomaly forecast for precipitation but the temperature has no strong signal," he noted.
Metro Vancouver is also moving out of a strong El Niño year that produced drier conditions, the warmest December on record, and daytime highs in the mid to late teens in late January.
El Niño is transitioning to ENSO-neutral but the National Oceanic and Atmospheric Administration's Climate Prediction Center isn't calling for an immediate shift to La Niña conditions.
"There is no forecast for a bonafide La Niña," said Doyle. "There is a flip but it isn't a convincing one."
