A stationary ridge of high pressure brought above-seasonal temperatures to British Columbia on May 4 and 5, Environment Canada reported in its provincial weather summary issued at 18:07 PDT on Tuesday, May 5.
Daily records include Lytton at 33.5°C (92.3°F), breaking the previous record of 32.3°C (90.1°F) set in 2013, with records kept since 1921; Smithers at 25.8°C (78.4°F), breaking 25.2°C (77.4°F) set in 2013, with records kept since 1938; Kitimat at 25°C (77°F), breaking 23.0°C (73.4°F) set in 1998, with records kept since 1951; and Sandspit at 16.3°C (61.3°F), breaking 15.7°C (60.3°F) set in 1981, with records kept since 1945.
At least 19 British Columbia communities set new daily records on May 4, including Vancouver, Richmond, Squamish, Port Alberni, and Pemberton. Pemberton reached 31.5°C (88.7°F), the highest reported value among the listed May 4 locations.
BC Hydro said increased use of fans and air conditioners pushed provincial electricity demand to about 7 600 MW, marking the highest May demand level recorded by the utility.
May is a seasonal transition period in the Northern Hemisphere, when above-seasonal warmth begins increasing wildfire susceptibility in areas experiencing early drying.
