Manitobans aren’t imagining it — the wild temperature swings we’ve seen lately are part of a growing global pattern scientists call weather whiplash. The term describes rapid flips between extremes, such as going from unseasonably warm to sharply colder conditions within hours. These sudden shifts are becoming more common in many parts of the world, and researchers say climate change is playing a major role.
Weather whiplash happens when the atmosphere transitions quickly between contrasting air masses. As the planet warms, those contrasts can become more pronounced, allowing warm, moist air to surge into regions that are normally cooler for the season. When that air is suddenly replaced by a cold front, temperatures can plunge dramatically — sometimes by 20 degrees or more in a single day.
Studies highlighted by climate researchers show that major cities across North America, Europe, and Asia are experiencing more frequent and more intense whiplash events. Large urban centres like Chicago, Beijing, and Madrid have all recorded rapid temperature swings that would have been considered rare just a few decades ago. Scientists warn that these abrupt changes can strain infrastructure, increase energy demand, and create challenges for agriculture, transportation, and public health.
Here in Manitoba, the recent 20-25‑degree temperature drop in just 12 hours fits the pattern. While the Prairies have always been known for fast‑changing weather, the speed and severity of these swings are becoming more pronounced. Experts say this trend is likely to continue as the climate system becomes more unstable, making weather whiplash a phenomenon Canadians will need to watch more closely in the years ahead.
Wednesday’s daytime high temperature reached + 16 in Brandon before plunging to -7 celsius by Thursday morning.
