Official forecast released by the National Climate Center in April:

El Niño will officially take shape in May 2026, developing into a moderate or stronger event throughout summer and autumn and lasting until the end of the year.

With flooding in the south and drought in the north overlapping with an extended extreme heat season, fresh food, pharmaceuticals and cold chain logistics are facing severe challenges.

Climate Warning: How El Niño Reshapes the Cold Chain Industry

1. Nationwide High Temperature: The Ultimate Cooling Challenge

• Longer heat duration: Temperatures across most regions rise by 0.5–1°C, with a sharp increase in extreme hot days above 40°C.

• Overloaded operation: Refrigeration units run at full load around the clock, driving fuel and power consumption up by 20%–30% and raising failure risks sharply.

• Cargo loss risks: High temperatures accelerate bacterial reproduction and greatly shorten the shelf life of fruits, vegetables, meat and vaccines. Minor temperature deviations will lead to total cargo loss.

2. Southern Floods & Northern Drought: Polarized Regional Supply and Demand

• Southern regions (Yangtze River Basin & South China): Hit by dual threats of flooding and high temperature. Disrupted roads and delayed deliveries; persistent damp heat drastically increases risks of condensation and cargo mildew inside containers.

• Northern regions (North China & Huanghuai Plain): Normalized high temperature and drought. Strong demand for drought-relief supplies, off-season fruits, vegetables and meat. Long-distance trunk transportation suffers from intense sun exposure and extreme temperature differences.
