These are typical climate conditions for thousands of locations across the
United States. Normals are calculated for a uniform 30-year period, and consist
of annual/seasonal, monthly, daily, and hourly averages and statistics of
temperature, precipitation, and other climatological variables from almost
15,000 U.S. weather stations. We have converted the hourly normal for the 600
stations available each for 1981-2010, 1991-2020, and 2006-2020 into EPW and
other formats.</p></div>
