El Niño Is Returning — What It Means for Extreme Weather, Food Prices, and Your Emergency Plan

As reported this week by a major news outlet covering the 2026 hurricane season forecast, climate models are pointing to the likely development of El Niño by mid-2026 — with its strength still uncertain. El Niño is a periodic warming of the central and eastern Pacific Ocean that disrupts weather patterns globally, typically bringing increased rainfall and flooding to some regions while triggering drought in others. The last significant El Niño event, in 2015–16, was among the strongest on record and was linked to food crises, wildfires, and extreme flooding across multiple continents.

What El Niño Typically Does

In the United States, El Niño years tend to bring wetter, cooler winters to the southern states and drier, warmer conditions across the Pacific Northwest and northern plains. In the UK and Europe, El Niño is associated with milder, wetter winters and increased flood risk. Globally, it disrupts agricultural production — particularly in Southeast Asia, Australia, and sub-Saharan Africa — which ripples through global food supply chains and contributes to price spikes.

The Food Price Connection

UK food prices are already 50% higher than 2021 levels. El Niño adds further upside risk. The 2015–16 event contributed to significant price increases in staple commodities including wheat, corn, and palm oil. With global food systems already stretched, a strong El Niño event in 2026–27 could amplify the food inflation that UK and US households are already absorbing. A home food store becomes more valuable — and more financially rational — the more volatile global food prices become.

Flooding: The Underestimated Risk

El Niño years in the UK are statistically wetter than average, increasing the probability of flooding events. The UK suffered over £1.3 billion in flood damage in 2023–24. For households in flood-prone areas, El Niño makes this the right time to review flood insurance, check that important documents are stored in a waterproof container, and ensure emergency bags are accessible on an upper floor.

Water Storage Paradox

It may seem counterintuitive to store water when flooding is a risk — but flood water is typically contaminated and unusable for drinking without treatment. Whether your concern is drought (reduced supply), flooding (contaminated supply), or infrastructure disruption (no supply), stored clean water and a quality filter are the universal solution.

Wildfire Risk in Drought Regions

For households in the Western US and Southwest, El Niño can paradoxically increase wildfire risk by suppressing Atlantic hurricanes while bringing drier conditions to already drought-prone areas. California and the broader Southwest face elevated fire risk during El Niño years. For households in these regions, a ready go-bag with key documents, medications, phone chargers, and water is the single most important preparation.

The Uncertainty Argument for Preparing Now

Climate scientists are clear on one point: El Niño's strength in 2026 remains uncertain. It could be mild or historically strong. That uncertainty itself is the argument for preparing now. A household that builds basic resilience — water storage, a food buffer, backup power, a go-bag — is protected against the mild scenario and the severe one equally. The cost of that preparation is small. The cost of being unprepared for a strong El Niño event is not.
