The 2026-27 El Niño is forecast to be one of the strongest in decades. This means that early preparation is needed for potentially extreme weather from flooding to drought-like conditions and other impacts like potential transport disruptions.
The effects of El Niño can vary depending on its strength, the time of year, and part of the country you live in. Earth Sciences New Zealand is predicting a significant El Niño could influence weather patterns from this spring onwards.
With advanced warning and well-planned preparations, growers and crops can get through El Niño weather patterns.
Growers are encouraged to make a plan and continue to review and revise those plans as the season evolves. Check out MPI's farm checklists to support planning.
It’s a good idea to think about the outcomes you want to achieve and set specific dates for making key decisions depending on financial, weather, soil, moisture, and crop conditions at those times.
You are not in this alone, discuss your plans with trusted advisors, your neighbours and other industry professionals.
Regional councils may have climate and/or hydrology information on expected conditions for the coming season, and further support available.
