- Super El Niño is rapidly strengthening, with forecasts indicating it could peak as one of the strongest events on record.
- The latest ocean and atmospheric data suggest the phenomenon is strengthening unusually quickly and could reach peak intensity by late fall or early winter.
- The August forecast reveals the next phase of development, reshaping the jet stream and influencing weather patterns.
- Canada could experience warmer-than-normal temperatures across much of central and eastern Canada during the fall, along with a shifting jet stream that changes where storms track across the country.
- The event is expected to influence temperatures, precipitation and storm tracks across much of Canada through the 2026–27 season.
- Forecast models suggest a persistent area of high pressure over Canada, generally favoring milder-than-average conditions while pushing the main storm track farther south into the United States.
- The strength of this developing Super El Niño makes it a significant driver of the upcoming fall and winter weather pattern.
A rapidly developing Super El Niño is set to significantly impact Canada's weather this fall and winter, with forecasts indicating it could become one of the strongest events on record.147
The latest ocean and atmospheric data show that sea surface temperature anomalies are already exceeding the threshold for a strong El Niño, with some models projecting record-breaking intensity later this year.
Forecasters predict that Canada will experience warmer-than-normal temperatures across much of central and eastern regions, alongside a shifting jet stream that will alter storm tracks.
Specifically, Canada could see drier-than-normal conditions in parts of western, southern, and northeastern areas this fall, while periods of cooler weather may occur in eastern Canada as low-pressure systems develop.
By winter, forecast models suggest a persistent area of high pressure over Canada, favoring milder-than-average conditions while pushing the main storm track farther south into the United States.6
The strength of this developing Super El Niño makes it a significant driver of the upcoming fall and winter weather pattern, with potential impacts lasting through the 2026–27 season.
July weather patterns across North America have already begun to resemble those observed during previous Super El Niño events, indicating that the atmospheric response is becoming apparent.
As the event progresses, Canada could experience one of its warmest El Niño winters in years, although regional variations remain likely.
“Forecast models indicate that Canada could experience warmer-than-normal temperatures and a shifting jet stream this fall, with significant impacts on precipitation patterns. By winter, a persistent high-pressure area may lead to milder conditions across much of Canada, pushing storm tracks further south into the United States.”
