Historical and Forecast City Specific Weather Data

Historical and forecast hourly data files are updated nearly every hour of every day, while historical and forecast daily data files are updated once or twice per day. While data files are available for download on the website and by ftp, much of the data can also be viewed graphically on the website for each location. The map to the right shows the locations for which we have forecast data available. Historical data is available for the same locations, as well as some additional locations not shown with a shorter period of record.
