La Niña in Australia

La Niña is a change in Pacific Ocean temperatures that affects global weather.

Typical impacts on our climate:
• Rainfall increases in eastern, central and northern Australia.
• Temperature decreases south of the tropics (daytime temperatures).

La Niña typically means:
• more tropical cyclones
• increased chance of widespread flooding
• longer duration heatwaves in southeast, but less intense
• earlier first rains across northern Australia
• increased chance of Indian Ocean heatwaves.

But every La Niña is different.

Rainfall during La Niña can vary considerably.
