A powerful oceanic Kelvin wave has intensified, effectively ending the multi-year La Niña influence. This shift raises concerns about changing climate conditions as forecasts indicate significant alterations in precipitation and temperature.

Key predictions for Summer 2026:

• A low-pressure area is forecast over eastern Canada and the northeastern United States.
• Above-normal temperatures are anticipated across the northwestern United States and western Canada.
• More rainfall is expected over the western, central, and northeastern United States, as well as the Midwest and southeastern Canada.
• Less precipitation is forecast over the far southern United States and across southern and central Canada.

The latest ECMWF and UKMO models show a stronger El Niño signature in the Summer 2026 pressure patterns than earlier updates. The average-to-upper value of the forecast indicates a very high chance for a Super El Niño to develop.
