June was far cooler and wetter this year compared to 2021

Wet, cooler June this year

After record-setting high temperatures hit most of B.C. in June of 2021, the Okanagan saw a big drop in temperature and a spike in precipitation through last month.

This year's month of June continued May's pattern of cooler and wetter conditions across the region.

“What we’ve seen this year is that persistence of cold, wet patterns for Kelowna and Vernon," said Environment Canada's Lisa Erven.

"Both those communities saw 140 per cent of their normal precipitation, so just more widespread rain over that region in particular. Penticton was near normal and as you got up towards Kamloops, the station at the airport only saw about 60 per cent of its normal precipitation."

The general weather trends across the Southern Interior was colder than normal temperatures. Environment Canada says the temperature anomaly was anywhere from about 0.5 - 1 C cooler than normal, but compared to last year’s "heat dome" in late June, it’s a massive drop.

“It’s apples to oranges. This spring and early summer of this year has been cool and wet predominantly across much of B.C., but if we think back to June of 2021 that’s when the majority of B.C. underwent the heat dome, which we saw record breaking temperatures not just for the province but for all of Canada for multiple days in a row," Erven said.

"With those conditions in place, communities all across B.C. saw their hottest June on record, which includes Penticton, Kelowna, Vernon and Kamloops all coming in anywhere from about 3-5 degrees above normal."

Looking at the numbers, Kelowna saw roughly 65 millimetres of rain this past month and only 13.5 millimetres in 2021 – a difference of 51.5 millimetres.

“May and June are typically some of the wettest months for the Okanagan and Kamloops because the weather pattern is so often dominated by either what we call upper low systems, which bring widespread precipitation, or just day-to-day conductions, so that’ll be your afternoon and evening showers and thunderstorms," said Erven.

The region is forecast to see the mid-20s and low-30s through the first week of July.
