The paper presents the results of remote assessing the state of winter crops in the southern regions of the European part of Russia in spring 2020. It is noted that the weather conditions of the 2019–2020 season are quite unique: due to the warm snowless winter, the active spring development of winter crops began several weeks earlier than the average in recent years. Since this factor maked it much more difficult to analyze the state of crops, we used a tool for normalizing NDVI data and meteorological indicators for the sum of accumulated active temperatures. This allowed us to assess the state of winter crops in the south of the European part of Russia, taking into account the seasonal specifics of the year. We have found that despite the increased values of the NDVI index, winter crops in many areas of the Republic of Crimea, Krasnodar and Stavropol territories and Rostov region are actually developing close to the long-term rate. In some areas of the Republic of Crimea, Krasnodar territory and Rostov region the development of winter crops in April 2020 is slightly worse than the situation in 2018 and 2019. Some risks of unfavorable winter crops development exist caused by a lack of precipitation and reserves of productive moisture in the soil. In the future, the development of winter crops in the southern regions of Russia will strongly depend on the availability of precipitation.
