The National Climatic Data Center, located in Asheville NC, provides a wealth of weather and climate data as well as summaries of climate at a variety of time and space scales.  The “State of the Climate” page provides links to a number of monthly climate summaries which describe conditions in other areas of the world, including those with crops that compete with agriculture from the Southeast.  Here is the website for the page: https://www.ncdc.noaa.gov/sotc/.
