During the monitoring period (July to September 2026), moisture and temperature conditions were generally favorable across Canada's agricultural areas, and crop conditions remained good. CropWatch agroclimatic indicators show that accumulated precipitation reached 199 mm, 9% above the average for the same period over the past 15 years, while mean air temperature was 17.9 °C, 0.4 °C above average. Accumulated photosynthetically active radiation was 771 MJ/m², 4% below average. The combined radiation, temperature and moisture conditions resulted in accumulated potential biomass of 712 g DM/m², 4% above the long-term average for the same period, indicating generally favorable weather for biomass accumulation. National VCIx was 0.95, CroPI was 1.10, and the cropped arable land fraction (CALF) reached 100%, 3% above the average for the same period over the past 5 years. These indicators point to widespread cultivation and generally good vegetation conditions.
Among the main agroecological zones, the Prairies were the main contributor to the favorable national crop conditions, with precipitation 12% above average, mean air temperature 0.5 °C above average, accumulated potential biomass 6% above average, and a maximum vegetation condition index (VCIx) of 0.96. In the St. Lawrence Basin, precipitation and accumulated potential biomass were 6% and 5% below average, respectively, but VCIx remained at 0.95, indicating generally stable crop conditions. In the Hudson Bay region, precipitation and accumulated potential biomass were 16% and 14% below average, respectively, suggesting that localized moisture shortages somewhat constrained biomass accumulation. In Western Canada, precipitation was 15% below average and VCIx was 0.83, with crop conditions weaker than the national average. Agriculture and Agri-Food Canada's September assessment also noted that precipitation eased drought in the southern Prairies, but excessively wet soils delayed harvesting. By September 28, 63% of the harvest in Saskatchewan had been completed, compared with the 5-year average of 91% for the same date. The effects of persistent precipitation on harvest progress and the quality of wheat and canola warrant attention.
Monitoring by crop indicates yield changes of +2.09%, +3.12% and +3.12% for wheat, maize and soybean, respectively, all showing modest positive signals. Within their respective crop monitoring areas, the CALF values for wheat, maize and soybean remained on par with the same period last year, reflecting generally stable cropland planting activities in the relevant areas. The generally good vegetation conditions nationwide and favorable moisture and temperature conditions in the Prairies provide some support for major crop production during this period. However, localized dryness and excessive moisture during harvesting may still affect the final harvest.
