Australia exhibits an overall winter-wet and summer-dry climate pattern. During the monitoring period, under the influence of an El Niño climate regime, agrometeorological conditions during the winter months of May–July were generally humid, with winter wheat primarily in the critical establishment stage spanning sowing, emergence, and early vegetative growth, and soil moisture was generally adequate.

CropWatch agrometeorological indicators showed that national cumulative precipitation averaged 132 mm, 12% above the 15-year average, effectively improving soil moisture and adequately ensuring wheat emergence and root establishment. The mean temperature was 12.5°C, 0.6°C above the long-term average, providing favorable thermal conditions with no significant temperature stress. Photosynthetically Active Radiation was 4% below the 15-year average; cloudy weather slightly reduced photosynthetic accumulation efficiency. The overall growing environment was characterized by sufficient moisture, and favorable soil moisture effectively supported wheat emergence and seedling growth. CropWatch monitoring indicated a national cropland planting fraction of 91%, the VCIx of 0.91, and the CroPI of 1.22, indicating a generally favorable stage-specific production outlook.

Influenced by the 2026 El Niño climate effect and rising agricultural input costs, Australia's 2026 winter wheat production is expected to follow a weak trend characterized by reduced planted area, declining yields, and lower total production year-on-year. Anticipating drought risks in late autumn and winter, farmers actively reduced sowing scales to mitigate production risks associated with soil moisture depletion and intensified dry-heat stress in later growth stages. Wheat planted area is projected to decrease from 12,341 thousand hectares last year to 11,717 thousand hectares, a year-on-year decline of 5.1%. As the crop growth cycle progresses, late-stage dry-heat stress will continue to inhibit wheat grain filling and dry matter accumulation. The national average wheat yield is expected to fall by 5.1% year-on-year, decreasing from 2,335 kg/ha to 2,215 kg/ha. Driven by the combined impact of contracted planting area and declining yields, total wheat production this year is projected at 25.95 million tonnes, a marked year-on-year decrease of 27.5%. Although soil moisture was adequate and seedling growth was favorable during the early monitoring period, the potential for late-stage drought risk associated with El Niño persists, production uncertainty has increased markedly, and the overall agricultural production situation remains under pressure.
