The monitoring period covers the final stages of the Maize and spring wheat cultivation and harvesting, as well as planting of winter wheat.

Compared to average, CropWatch agroclimatic indicators show that the conditions were abnormal at the national level. This includes a 18% drop in RAIN, slightly above average temperature, and a very significant increase in sunshine (RADPAR +10%). The resulting BIOMSS indicator is down 13%, the main crop production estimates at put at 4.5% below 2017 for wheat and 1.5% down for Maize. 

The NDVI development graph for the entire country indicates crop condition below the average of the past five years and 2017. The spatial NDVI patterns compared to the five-year average indicate that NDVI is above average in 19.8% of arable land just in August  and with below average values in the other regions.

This spatial pattern is reflected by the maximum VCI (VCIx) in the different areas, with a VCIx of 0.95 and low CALF(0.73) for France overall.

Regional analysis

Considering cropping systems, climatic zones, and topographic conditions, additional sub-national detail is provided for eight agro-ecological zones. They are identified in the maps by the following numbers: (54) Northern barley region; (58) Mixed maize/barley and rapeseed zone from the Center to the Atlantic Ocean; (55)Maize_barley and livestock zone along the English Channel, (56) Rapeseed zone of eastern France;(51) Dry Massif Central zone; (57) Southwestern maize zone; (52) Eastern Alpes region and (53), the Mediterranean zone. 

In the Northern barley region both TEMP and RADPAR were above average (0.5°C and 16%, respectively), while RAIN was 32% below. Low VCIx values (0.66) reflect overall unsatisfactory crop condition.

The Mixed maize/barley and rapeseed zone from the Center to the Atlantic Ocean experienced average temperature, RAIN was 32% below average, while RADPAR was 13% above. According to the NDVI profile and VCIx map, crop condition was not good in the region.


The Maize/barley and livestock zone along the English Channel recorded 144 mm of rainfall over four months(RAIN -35%). Temperature was average (TEMP 0.2°C), but RADPAR was 11% above. The drop in BIOMSS was 12% compared to the five-year average. The NDVI profile confirms the  conditions of crop was not good but close average.

Mostly unfavorable climatic conditions dominated the Rapeseed zone of eastern France over the reporting period. Rainfall was 41% below average (181 mm over four months).Temperature was normal, but radiation was 15% above average. The dry conditions have hampered crop growth, indicated also by a BIOMSS indicator 27% below average for the period.

The Dry Massif Central zone recorded a 32% rainfall deficit, with above average values for both RADPAR (13%) and TEMP(1.1°C). BIOMSS for the region is 20% below the five-year average, and a low VCIx value reflects the generally unsatisfactory crop and especially pasture condition, as confirmed by the NDVI development graph.

The Southwestern maize zone is one of the major irrigated maize regions in France. But rainfall only dropped 5% below average, temperature was average, but radiation was above expectations (RADPAR+7%). Crop condition was below average according to the NDVI development graph, as confirmed by the decrease of BIOMSS by 3% compared to the 5YA. The VCIx map, however, shows that the crop condition was unsatisfactory.

Generally, environmental conditions for the Eastern Alpes region were close to average with the following values: RAIN +11%, TEMP +0.9°C, and RADPAR +6%. Almost all arable land in this region was cropped during the monitoring period, and the average VCIx is 0.78.The NDVI profile confirms the crop condition.

Finally, the most favourable weather conditions were observed in the Mediterranean zone (RAIN +52%) even if other indicators remain close to average, except for TEMP (+1.4°C). According to the NDVI profiles, crop condition remained favorable since July. BIOMSS is 19% above its five-year average, and the VCIx value of 0.91 for the region is the highest in the country.
