Indicators in Australia show generally average condition for the January to April period, which is out of season for wheat and barley. The maximum VCI is 0.64 throughout the region, with a 3 percentage point increase in CALF compared with the recent five-year average. Compared to the same average, the spatial NDVI patterns and corresponding time profiles show below average conditions in central and northern New South Wales, with agroclimatic and biomass indicator departures for this state as follows: RAIN, -6%; TEMP average; RADPAR, -1%; and BIOMSS, -5%. Nationwide, agroclimatic indicators display average conditions (RAIN +14%, TEMP +0°C, and RADPAR -2%), resulting in a slightly positive biomass accumulation potential (BIOMSS +7%) compared with recent years. Positive departures of rain were recorded in South and Western Australia (+47% and +29%, respectively), contributing to favorable soil moisture conditions for the planting of wheat and barley in the coming month.
