sofver Posted April 5, 2014 Share Posted April 5, 2014 Hi everyone, I'm trying to locate an online source for hourly historical weather data by zip code or city, particularly in the DC/VA/MD region, going back at least the past two years. I've been able to identify several sources that give historical averages by day, but that's not really granular enough for my purposes. Could anyone please recommend a good source? (I apologize, sincerely, if this seems like a really obvious question. I'm a total newbie at this.) Thank you! Link to comment Share on other sites More sharing options...
e pluribus unum Posted April 5, 2014 Share Posted April 5, 2014 Wunderground has hourly ob history back to the 1940s for major airports. DCA, for example, goes back to 1947 http://www.wunderground.com/history/airport/KDCA/1947/5/5/MonthlyHistory.html#calendar And IAD back to 1962 http://www.wunderground.com/history/airport/KIAD/1962/11/5/MonthlyHistory.html Full METARs start in 1973 Link to comment Share on other sites More sharing options...
