China Winter Alert: Super El Nino Fuels Extreme Weather
3 Nov
Summary
- Super El Nino event expected to cause volatile winter weather in China.
- Cold waves, heavy snow, and freezing rain risks are heightened.
- Temperatures may swing sharply, with varied impacts across north and south.
China is poised for a winter marked by significant volatility, as a powerful super El Nino event takes hold in the Pacific. The China Meteorological Administration has issued warnings of more frequent cold waves, alongside heightened risks of heavy snowfall and freezing rain across the country.
The super El Nino, which strengthened considerably by October, is anticipated to reach its peak in late autumn or early winter. Its influence is projected to extend through the upcoming spring, bringing substantial changes to China's climate patterns.
While overall temperatures for the 2026-27 winter are expected to hover near or above the seasonal average for much of the country, frequent and sharp temperature swings are predicted for December and January. Despite a generally warmer outlook for the latter half of the season, cold waves are still forecast to occur more often than usual.
Northern China is particularly vulnerable to severe cold snaps and substantial snowfall. Conversely, southern regions are likely to contend with more frequent episodes of low temperatures, rain, snow, and freezing rain. Nationwide precipitation is expected to exceed average levels, with widespread heavy snowfall anticipated across much of northern China.
In the southern parts of the country, including East, Central, South, and Southwest China, above-average precipitation is forecast. These areas also face the possibility of intermittent cold, snowy, and icy conditions.
The nation is projected to experience four cold air outbreaks in November. The intensity of these events is expected to be greater in the first half of the month. Cold air activity in northern China could be strong periodically in November, leading to temporary low temperatures, strong winds, and frost.
Authorities are urging agricultural and livestock operators to bolster protective measures for facilities and animals. Transport, energy, and power sectors are also advised to prepare emergency response plans for potential low-temperature, rain, and snow-related disasters.
