Jon Tunster from Earth Sciences New Zealand shared insights on the current climate situation. He noted, “La Niña has only just ended, but there are indications that we’ll see a rapid flip to El Niño.” This transition has been monitored closely for six months, with climate models suggesting a south-westerly flow over New Zealand due to El Niño’s atmospheric response.

The forecast indicates a 60 percent probability that this El Niño will be classified as ‘strong’ by spring. This strength raises concerns about potential dry spells for many regions as spring approaches. Jon Tunster emphasized, “Dryness could become an issue as spring approaches for areas that see a reduction in their normal winter rainfall.”

Alongside the expected rainfall changes, the winter is unlikely to be colder than usual. However, occasional cold snaps may occur—lasting a few days at a time—especially in inland parts of the South Island where cold air can linger longer.

As communities prepare for these shifting weather patterns, farmers and residents alike are bracing for the impacts. The anticipated increase in rainfall in some areas could be beneficial for crops that thrive on moisture. Conversely, those in drier regions may need to strategize on water conservation and crop management.

Experts have noted that El Niño and La Niña are phases of the El Niño-Southern Oscillation (ENSO), which dramatically influences global weather systems. The ongoing effects of this cycle could have ripple effects beyond New Zealand, impacting weather patterns across continents.

Looking ahead, while officials have not confirmed the exact extent of El Niño’s impact on New Zealand’s winter weather, the signs point toward significant changes. With a 90 percent chance of El Niño conditions by July through September, residents should stay informed and prepared for whatever this unpredictable season may bring.

Key facts:

• There is a greater than 60% probability that the El Niño event will be classified as ‘strong’ by spring.
• El Niño events often result in south-westerly winds over New Zealand, leading to increased rainfall in the south and west.
• This winter could bring dry conditions in the north and east while wetter conditions are likely in the west.

Jon Tunster, a meteorologist with Earth Sciences New Zealand, noted, “La Niña has only just ended, but there are indications that we’ll see a rapid flip to El Niño.” He added, “Given the projected strength of this event, it will be very surprising if New Zealand doesn’t feel some impacts.”

The Relative Oceanic Niño Index (RONI), which tracks ENSO conditions, is already showing a rapid rise consistent with the onset of El Niño. Warm sub-surface waters in the tropical Pacific Ocean are key indicators of significant El Niño events.

Daniel Kingston also emphasized that “put simply, El Niño is often associated with large-scale releases of heat from the tropical Pacific Ocean.” He warned that if projections hold true, “the impacts may be substantial.”

While officials expect notable changes in weather patterns, they acknowledge uncertainties remain. The exact strength of this El Niño event will become clearer in the coming months.

According to Earth Sciences New Zealand, the effects of El Niño will start manifesting from winter onwards. Areas such as Southland, parts of Otago, and western-facing regions of the South Island could experience increased rainfall. In contrast, much of the rest of New Zealand may face reduced rainfall.

Jon Tunster from MetService noted, “La Niña has only just ended, but there are indications that we’ll see a rapid flip to El Niño.” He added, “Given the projected strength of this event, it will be very surprising if New Zealand doesn’t feel some impacts.” This sentiment echoes concerns about potential dryness in areas like the east of both islands and the upper North Island.

As global temperatures approach a critical threshold—1.5 degrees Celsius—the implications of climate change intertwine with these weather patterns. Associate Professor Daniel Kingston emphasized that “El Niño is often associated with large-scale releases of heat from the tropical Pacific Ocean,” which can dramatically affect global weather systems.

The forecast also suggests that occasional cold snaps may occur throughout the winter, lasting a few days at a time. This variability adds another layer of complexity to how communities prepare for the season ahead.

Earth Sciences New Zealand has been monitoring signs of a developing El Niño for six months. Models indicate that warm sub-surface waters are likely to reach the surface soon, further strengthening atmospheric responses.

As we look ahead, observers expect substantial impacts if the event unfolds as predicted. The next few months will be critical for understanding how these changes in climate will affect local communities and their resources.

The forecast predicts a greater than 60% chance that this El Niño event will be classified as ‘strong’ by spring. Warm ocean temperatures in the central and eastern tropical Pacific are driving this shift, leading to expectations of varied rainfall across different regions.

Expected impacts this winter:

• Increased rainfall is anticipated for Southland, parts of Otago, and western-facing areas of the South Island.
• Much of the remainder of New Zealand may experience reduced rainfall.
• Dry conditions might become concerning as spring approaches in areas with less winter precipitation.
• Occasional cold snaps could occur, lasting a few days at a time.

Tunster emphasizes the importance of monitoring these changes: “Given the projected strength of this event, it will be very surprising if New Zealand doesn’t feel some impacts.” The atmospheric response from El Niño may also strengthen high-pressure systems over Australia during the winter months.

This year marks a notable shift after an extended period of La Niña conditions. For six months, scientists have monitored signs of developing El Niño. The Relative Oceanic Niño Index (RONI) shows a rapid rise consistent with its onset. Warm water beneath the surface of the tropical Pacific Ocean is moving eastward—an indicator that significant changes are on the horizon.

Key indicators include:

The atmospheric response expected as warm sub-surface waters reach the surface. and Potential dramatic impacts on large-scale global weather systems, including the Indian monsoon and North Pacific storm track.

As winter approaches, communities across New Zealand are advised to prepare for these potential shifts in weather patterns. While some regions may benefit from increased rainfall, others might face challenges due to dryness. The next few months will be crucial in understanding how these changes will unfold.
