Corner Brook’s all-time high temperature is 37.2°C, set on August 11, 1944, while the lowest recorded temperature is -29.4°C, from February 11, 1948. These extremes, captured over decades of observation, place the city’s climate in a fascinating western Newfoundland context.
How do Corner Brook’s daily records compare to the live forecast above?
The live forecast above shows conditions that generally fall well within the city’s historical boundaries. Corner Brook’s climate is moderated by the Bay of Islands, so summer heatwaves rarely approach the 1944 record, and winter cold snaps seldom dip below -25°C. When the forecast nears these thresholds, it often signals a significant weather pattern shift worth watching.
What’s the most unusual weather record for Corner Brook?
Perhaps the most striking record is the 24-hour rainfall. On September 11, 2011, a slow-moving low-pressure system dropped 119.8 mm of rain on the city—more than twice the average for the entire month. Such intense precipitation events are rare but becoming more notable as regional climate patterns evolve.
Does Corner Brook ever break its own heat records anymore?
Extremely rarely. The 1944 high has been approached only a handful of times, most recently in July 2020 when the city reached 35.3°C. Urban development and changing air masses make new records possible, but they remain exceptional events.
What’s the coldest Corner Brook has ever felt with wind chill?
While the official low is -29.4°C, wind chill values have dipped below -40 during fierce nor’easters. The combination of strong winds and cold air can make February afternoons feel like -38, though such extremes are less common than in central Canada.
How does Corner Brook’s record compare to other Newfoundland cities?
Corner Brook runs cooler in summer than St. John’s (record 33.1°C) but warmer in winter than Gander (record -34.4°C). Its record high is the highest on the island’s west coast, thanks to those rare warm downslope winds off the Gulf of St. Lawrence.
