Overall, crop condition in Mexico was above the five-year average between April and early July. During the monitoring period, last year’s winter wheat and secondary maize wereharvested; this year’s maize is still growing. The CropWatch agroclimatic indices show that rainfall, radiation, and temperature were close to average(only deviating by -4%, -2% and -0.1°C, respectively). According to the crop condition development graph based on NDVI, the NDVI values at the national scale exceeded the past five-year maximum from April to May; since June, the values were close to or below the maximum. Finally, in late July, the value wasagain below the last five year average. Over the reporting period, the biomassaccumulation potential (BIOMSS) was significantly above average (+14%).More over, the cropped arable land fraction (CALF) increased slightly comparedto average (+5%). Considering both favorable condition of growth and increasedCALF, the yields of summer crops in Mexico are expected to be above the five-yearaverage.
