Teachers can also download files of local climate data for free. This information would be useful for teachers who want to insert real data into lessons or activities they develop. Choose the state, and then the local/regional area. If you want to compare the months (seasons), request the annual summary for a year (following the 12th monthly report for that year). It opens as an 8-page document. The first page has three plotted graphs (max and min temperatures, daily precipitation, and daily station pressure). The seventh page has a narrative/text description of the climate factors for that location. You can save the entire file, or print selected pages.
