A strong El Nino event forming in the tropical Pacific is predicted to lead to dry weather and increased wildfire dangers in parts of New Zealand in the upcoming months. Earth Sciences New Zealand stated that El Nino conditions have emerged and could escalate to one of the most intense on record, potentially influencing weather patterns until 2027. Meteorologist Jon Tunster from Earth Sciences NZ and MetService highlighted that long-range models indicate drier conditions for northern and eastern New Zealand, with increased rainfall likely in western regions, especially in the South Island.
Tunster warned that various climate factors, such as temperature changes in the Indian Ocean, occasional impacts from Antarctica, and climate change, might affect New Zealand’s weather patterns. He emphasized that the ongoing El Nino event could significantly impact the weather from September onwards, with winds and reduced rainfall leading to soil dryness and heightened wildfire risks, particularly in hot, low-humidity conditions in the eastern and possibly northern parts of the country. Additionally, decreased rainfall may pose challenges for water-dependent sectors by limiting groundwater recharge.
Professor Anita Wreford, an applied economist at Lincoln University in New Zealand, advised that while the exact consequences are uncertain, vulnerable sectors could prepare by maintaining adaptable plans to adjust their operations as the situation evolves.
