Another heat milestone was reached Sunday in Chilliwack when the mercury rose to a blistering 36.5 degrees C.
The new high maximum temperature record for July 5 also marked an “unprecedented” 11 consecutive days of a heat wave above 30 degrees, said Roger Pannett, volunteer weather observer for Environment Canada.
Nine of those 11 days saw temperatures blasting above 32 C.
Sweltering Sunday saw the previous minimum, mean and maximum record highs set in 1958 “smashed” on that day, he said.
The minimum of 20 C overnight was almost nine degrees above normal, the high mean of 28.5 C was 11.35 degrees above normal, and the high maximum of 36.5 C was a staggering 14 degrees hotter.
“It was the hottest Chilliwack day since the all-time Chilliwack maximum of 38.2 C of July 29, 2009,” Pannett noted.
The last “substantial” rain was 22 mm on May 5, which was two months ago.
“This heat wave is far exceeding the nine consecutive days above 30 C recorded in the summers of 2004 and 2009!” he added.
