2026 ENSO Update: El Niño is likely developing. Most climate models now forecast tropical Pacific warming right through spring and summer. That usually means below average rainfall, above average temperatures, and higher fire risk across eastern Australia. The
Inigo Jones cycle (Bruckner dry phase) backs the drier read. Plan for drier conditions and higher fire danger.
