What El Niño means for Australian farmers heading into summer 2026-27

The second half of 2026 is shaping up as a significant test for Australian agriculture. While the winter has already been delivering below average rainfall across much of Queensland, New South Wales and South Australia, the bigger concern for producers right now is what comes next.

Climate forecasters are pointing toward El Niño conditions arriving in time for the 2026-27 summer growing and grazing season, and the implications for water security, livestock management and farm profitability are worth understanding clearly before the season turns.

What is El Niño and why does it matter for Australian farmers?

El Niño is a climate pattern driven by warming of the tropical Pacific Ocean. When it takes hold, trade winds weaken, ocean temperatures rise and global weather patterns shift measurably. For Australia, the result is typically reduced rainfall across the agricultural heartland, higher temperatures and a heightened risk of drought.

The pattern is well documented. Australia's most damaging drought years, including 1982, 1994, 2002, 2006 and 2015, all coincided with El Niño conditions. The consequences run through every part of the agricultural sector: reduced pasture availability, lower crop yields, tighter water allocations and compressed farm profitability.

The Bureau of Meteorology confirmed earlier this year that oceanic conditions have been transitioning from La Niña toward neutral conditions, with El Niño possible by mid-2026. Some international climate models have put the probability of El Niño developing as high as 90 per cent.

What the current data shows

The signs are already visible in the existing rainfall records. Bureau of Meteorology data shows that rainfall for the 36 months ending in May 2026 has been below average across large areas of western and south-western Western Australia, south-eastern South Australia and south-western Victoria, with some areas recording their lowest rainfall on record for those periods since 1900.

The Bureau's three-month outlook for June to August 2026 gives a 60 to 80 per cent chance of below average winter rainfall across cropping regions in Queensland, New South Wales, Victoria, South Australia and Western Australia.

For Queensland specifically, ABARES is forecasting a 38 per cent fall in winter crop production to 2.4 million tonnes in 2026-27, reflecting low soil moisture levels at planting and an unfavourable rainfall outlook. That would represent one of the more significant single-year production declines for Queensland in recent memory.

What it means for livestock producers

The pressure on livestock operations comes from multiple directions simultaneously, which is what makes El Niño years particularly difficult to manage.

Reduced pasture availability forces producers to purchase supplementary feed at a time when feed costs are already elevated. Research compiled by CSIRO and reported by ABARES indicates that El Niño typically reduces winter and spring rainfall during the critical growing season, compounding the feed availability problem heading into summer.

For a typical Australian beef farm, ABARES data shows that profit falls from around $60,000 in a typical year to a loss of approximately $5,000 in a dry year. Drought years also reduce herd sizes through higher sales, higher mortality rates and lower birth rates, with the financial impact extending well beyond a single season as producers work to rebuild numbers once conditions improve.

Livestock prices are currently strong, which creates a short-term buffer but also raises the stakes. Cattle prices have recently broken 1,000 cents per kilogram for the first time since 2022, and goat prices have reached $8 per kilogram on the back of strong market conditions. Every animal lost to poor nutrition, failing water infrastructure or disease represents a meaningful financial hit at current valuations.

Water security: the central challenge

The Murray-Darling Basin, which supplies roughly one third of Australia's food production, is subject to a 2026 Basin Plan Review that acknowledges the long-term trend toward a hotter, drier future. Water managers are already signalling tighter constraints for the coming water year.

CSIRO's Drought Resilience Mission research identifies water security as one of the central pillars of farm resilience. Their work highlights that implementing drought resilience measures before dry conditions arrive ensures regional Australia can endure deeper and longer droughts and recover from them faster, protecting both farm income and regional employment during the hardest years.

The practical implication for producers in Queensland and the Northern Territory is that water infrastructure decisions made in the next few months will directly determine how much flexibility an operation has if summer rainfall falls well short of average.

How producers are thinking about the season ahead

Experienced producers who have managed through previous El Niño cycles tend to approach the lead-up period with a focus on a few consistent priorities.

Herd and flock management is the first consideration. With strong prices across cattle, sheep and goats, the temptation is to maintain or grow numbers heading into summer. However, carrying more animals than the property's water and feed infrastructure can support during a dry period creates the conditions for rapid and painful destocking under pressure, which almost always happens at the worst point in the market cycle.

Water point reliability becomes non-negotiable when rainfall cannot be relied upon to recharge natural sources. Troughs that have been performing adequately through average seasons can become critical failure points when they are the only consistent water source available to stock over an extended dry period.

Supplementary feeding strategies that are planned and sourced in advance are substantially cheaper than emergency purchasing once dry conditions are already entrenched and supply chains are under pressure from other producers making the same decisions simultaneously.

The long-term picture

It is worth noting that El Niño is not the only force shaping Australian agricultural conditions. CSIRO and the Bureau of Meteorology's State of the Climate reporting documents a longer-term shift toward drier conditions across southern Australia, particularly during cool season months from April to October. Southern Australia has recorded below average April to October rainfall in 26 of the 32 years from 1994 to 2025.

For producers in Queensland and the Northern Territory, these trends underline the case for treating water security not as a seasonal consideration but as a permanent infrastructure investment priority.

The 2026-27 summer outlook doesn’t guarantee a severe drought

El Niño forecasts are probabilistic, not certain, and Australian seasons have a long history of defying expectations. What the current data does support is the case for preparation.

Producers who enter summer with robust water storage, reliable water points and well-conditioned stock will be in a substantially better position to absorb whatever the season delivers than those who are still working through their infrastructure list in October.
