La Nina Conditions Set to Fade as El Nino Risk Adds Climate Uncertainty

the World Meteorological Organisation

La Nina conditions are expected to fade into neutral weather patterns in the coming months, but the possibility of El Nino developing by May-July adds fresh uncertainty for global commodity and industrial supply chains. The World Meteorological Organisation said the current weak La Nina episode is likely to weaken, with neutral conditions becoming the most probable outcome.

The WMO forecasts a 60pc chance of neutral conditions in March-May and a 70pc chance in April-June. It also sees a 60pc chance of neutral conditions in May-July, while assigning a 40pc probability to an El Nino episode during that period.

La Nina conditions typically reduce global temperatures, while El Nino usually has a warming effect. However, climate change is increasingly overpowering the historical temperature effects of both patterns, making weather-related risk harder for industries to manage.

Weather Volatility Matters for Mining and Commodity Flows

Weather patterns are becoming an important supply-chain variable for mining, metals, energy, and agriculture-linked industrial markets. Heavy rainfall, drought, heat stress, cyclones, and power disruptions can affect mine output, transport corridors, hydropower availability, smelting costs, and port operations.

La Nina conditions often influence rainfall patterns across major resource regions. A shift toward neutral conditions may reduce some weather extremes, but it does not remove risk. The WMO cautioned that forecast uncertainty increases over longer timeframes.

An El Nino event would create a different set of risks. It can intensify heat, reduce rainfall in some regions, and disrupt water-dependent industries. For metals producers, this matters because water, electricity, and logistics reliability are central to mine and smelter performance.

Above-Normal Temperatures Keep Industrial Risk Elevated

The WMO also expects a widespread global signal for above-normal land surface temperatures in March-May. This is important because 2025 was still one of the hottest years on record, even though it began and ended with La Nina conditions.

Higher temperatures can affect industrial operations through power demand, grid stress, worker safety, water availability, and cooling requirements. Energy-intensive sectors such as aluminium smelting, copper processing, steelmaking, and battery materials production are especially exposed when weather volatility affects electricity supply or costs.

For commodity markets, the key issue is not only whether La Nina conditions fade or El Nino develops. The larger issue is that climate volatility is becoming a structural operating risk across upstream extraction, refining, and global transportation.

The Metalnomist Commentary

Weather risk is now part of industrial risk management, not a background variable. Metals and mining companies must treat climate volatility as a factor in production planning, logistics resilience, and long-term supply security.
