Overview
The NOAA US Climate Normals provide information about typical climate conditions for thousands of weather station locations across the United States. Normals act both as a ruler to compare current weather and as a predictor of conditions in the near future. The official normals are calculated for a uniform 30 year period for almost 15,000 weather stations, and consist of annual/seasonal, monthly, daily, and hourly averages and statistics of temperature, precipitation, and other climatological variables for each weather station.
In addition to tabular Climate Normal data for each weather station location, gridded Climate Normals for temperature and precipitation variables are also available. Daily, monthly, seasonal, and annual gridded Climate Normals are provided in 1/24 degree lat/lon (nominal 5x5 kilometer) grids for the contiguous United States.
