What Does La Nina Mean For Winter 2024. It could replace el nino before the end of summer. The latest forecast expects la niña to emerge this fall and persist through the winter.

El niño hasn’t even grown cold, but national forecasters say its counterpart, la niña, is already waiting in the wings to take over. So, when we know we’re heading into a la niña winter, we can probably count on normal to slightly below normal temps, but a strong el niño is a clearer signal of major warmth.
