Weather can play a significant role in a producer’s decision making process. However, the literature is void of research estimating the impact of weather patterns on days suitable for field work. The probability of having enough days available to do field work drives the machinery investment decisions, timing of field operations, and optimal risk management strategies. This study shows that when either an El Nino or La Nina cycle are present then the days available decrease. The number of days that decrease is dependent upon the location of the state and the specific cycle present. This model also shows that Arctic Oscillation cycles, specifically a negative cycle, do not impact days available.
