This past winter, weather in Canada has been affected by an El Niño event, which is known for warm, above-average temperatures in the Pacific Ocean. El Niño is usually followed by La Niña, which is associated with colder effects, leading to rainstorms or hurricanes. While both events occur in the Pacific Ocean, they affect global weather patterns. This year, the El Niño-Southern Oscillation (ENSO), the switch between the two phases, is expected to remain neutral until at least July due to various environmental conditions. The lull between the two phases does not have big impact on the weather.

Prof. Moore notes that the impacts of these events typically are seen during the winter, noting the widespread warmer temperatures and less snow this past season. The lingering effects of El Niño may persist into the summer, causing dry conditions and wildfires in Western Canada.

Canadians will likely witness slightly cooler temperatures in the next year, as La Niña is likely ushered in. However, the effects of La Niña won't be clear until the winter.
