North American wheat growing areas show variation in many different factors, one of the most varied and important being temperature. Temperature is well established to correlate with yield. Given data from the Uniform Soft Red Winter Wheat Nursery and independently gathered data from government-owned weather stations, I explored possible correlations between temperature and wheat yield that can be extrapolated to areas that are not covered by the Uniform Soft Red Winter Wheat Nursery database. My analysis did not reveal strong correlations between temperature and growth, and in some cases, the sample size was too small. From this study, it was found that average temperature is slightly correlated to average yield, with an R2 value of 0.1987. Average low temperature is slightly correlated as well, with an R2 value of 0.1917. Average high temperature was found not to be correlated at all, with an R2 value of 0.0023. While there are tangible values from these findings, more research is needed to expand on this correlation.
