Canada is on alert as meteorologists predict a strong El Niño phenomenon to commence in June 2026. This weather event, characterized by warmer than average surface waters in the eastern tropical Pacific, is expected to have significant implications for the country’s climate and weather patterns.
The upcoming El Niño is anticipated to peak in November 2026, with forecasts suggesting a temperature anomaly of 2.4°C. This is particularly concerning as the last strong El Niño, which occurred during 2015-2016, saw ocean temperatures rise approximately 2°C above average, leading to severe weather events worldwide.
Historically, the strongest El Niños were recorded in 1997-98 and 2015-16, both of which had profound impacts on global weather systems. The 2015-2016 event resulted in a record hurricane year in the central North Pacific and severe drought conditions in Ethiopia. As Canada prepares for the 2026 event, experts warn that it could exacerbate existing challenges, particularly regarding wildfire seasons.
According to Natasha Ramsahai, a meteorologist, “This is expected to strengthen into a very strong El Niño by the winter time of this year.” The implications for Canada could include extreme heat and increased wildfire risks, especially if hot weather coincides with lightning strikes, as noted by Anthony Farnell.
In addition to the immediate impacts, the 2026 spring forecast indicates wetter conditions in eastern Canada, while the Prairies may experience drier weather. However, April 2026 is expected to be colder than normal for much of the country, influenced by the polar vortex, which has already led to a tougher winter than usual in early 2026.
El Niño and its counterpart La Niña are part of the El Niño Southern Oscillation (ENSO), a cyclical climate pattern that affects weather globally. With 90 percent of excess heat from greenhouse gases trapped by oceans, the upcoming El Niño could further complicate the climate crisis.
As the situation develops, experts like Zeke Hausfather emphasize the potential severity of the upcoming El Niño, stating, “It seems like we’re in for a strong [El Niño] with a chance of a super strong El Niño event.” Details remain unconfirmed regarding the exact impact on specific weather patterns in Canada, but the urgency for preparedness is clear.
