Corn is an agricultural crop that is part of humanity's diet, directly or indirectly, having great relevance in Brazilian agriculture. Given this, it becomes essential to understand the development of culture in the various production environments. In addition to understanding the climatic factors involved in its cultivation. In this context, following guidelines on the sowing time defined by the Agricultural Climatic Risk Zoning (ZARC) of the Ministry of Agriculture, Livestock and Supply (MAPA), for all Brazilian municipalities is essential to increase the chances of success in crops. Thus, a case study was carried out to evaluate the degree of coherence of the sowing window proposed in the ZARC/MAPA for corn cultivation in the municipality of Uberlândia. Based on historical data obtained from the National Institute of Meteorology (INMET) and the National Water Agency (ANA), it was possible to process graphs of rainfall, temperature, relative humidity and solar radiation. In addition, using the Thornthwaite method, the water balance was obtained, showing prolonged periods of water deficit. Based on the verified data, it is suggested to shorten the sowing window for both seasons, starting the first summer season in the 32nd ten-day period and the second season in the 36th, ending both as soon as possible within the limit of the first ten-day period February.
