The La Niña Spanish for little girl climate pattern is one of the main drivers of weather around the world especially during the late fall winter and early spring. This weather increases the risk of wildfires in Florida and dryness in the North American plains. La Niña conditions recur every few years and can persist for as long as two years.

The Pacific Ocean has been showing signs of a developing La Niña since the middle of this year. The warming phase of the sea temperature is known as El Niño and the cooling phase as La NiñaThe Southern Oscillation is the accompanying atmospheric component coupled with the. Australias most significant driver of weather patterns La Niña is now active for a second consecutive year and will fuel weather systems with moisture for up to six months senior.
