The weather year was up and down in terms of Chilliwack temperature extremes in 2019, but mostly up.
Except for February and October, the monthly mean temperatures were above normal, according to Roger Pannett, volunteer weather observer in Chilliwack for Environment Canada.
With mean temperatures for 2019 at 1.29 C above normal, it was the seventh consecutive year with mean temperature in excess of the +0.6 C standard deviation, continuing the warming trend which started in 1986.
During the June-to-September period there were 12 hot days where the mercury soared above 30 C.
“It was the 18th consecutive year with well above the average seven hot days — a trend never previously observed,” Pannett said.
There were 19 record-breaking high temperatures in 2019 with only three low temperature records.
Temperature extremes for 2019 included the record-breaking maximum temperature of 34.5 C (13.8 C above normal.) on June 12, and the minimum temperature of –10.2 C (10.4 C below normal) on February 4.
However, February was the coldest on record with mean temperatures 5.03 C below normal at -0.33 C. (Previously 1922 and 1929 were the coldest Februaries with mean temperatures at -0.22 C).
In 2019 there were 211 frost free days compared to the average 216 days.
After the driest March since 1992, (78.82% below normal) six 24-hour rainfall records occurred, the most since 2003. However, for the seventh consecutive year, precipitation totals were below the 30-year average, – 28.43%, including snowfall at 42.8% below normal.
