We are fixing to making a road trip and wanted to know how the weather in different states on the East coast is like in different months.

Is there a map or a website available somewhere which gives the weather patterns for the East coast of the US?

    The National Weather Service has lots of data. Look under "Climate". Also, the Wikipedia pages for most major cities have a "Climate" section. Sep 5, 2013 at 15:38
  • @NateEldredge Thank you. I was looking for some place which gives details of all cities combined instead of having to open the wiki page for every city. Sep 5, 2013 at 16:39

You can find daily weather maps of the lower 48 at http://www.hpc.ncep.noaa.gov/dailywxmap/ since 2003; there are historical maps from 1871-2003 available at http://docs.lib.noaa.gov/rescue/dwm/data_rescue_daily_weather_maps.html but you'll need to download an additional plugin.

The article at http://en.wikipedia.org/wiki/Climate_of_the_United_States includes a basic climate map and links to descriptions of the seasonal characteristics of the "humid continental" and "humid subtropical" climate types.

Between http://www.worldclimate.com/ and http://www.weatherbase.com/ , you can find average weather for different stations for different months from around the world. I'd start with WeatherBase, as its data is more useful in my opinion, e.g. I prefer a temperature range to a mean temperature. On the other hand, WorldClimate includes more stations, and you don't need to convert if you don't know Fahrenheit.

For planning a road trip, I would not think weather would be your primary concern; it's hard to find a rental car without air conditioning, and in the north or in the mountains where you are likely to see snow in winter, the road crews are very good about keeping the highways and arteries clear (ice and snow are most dangerous where drivers are unaccustomed to it, like D.C. or Dallas). At any time of year there is the risk of a thunderstorm, tropical storm, and/or blizzard, but they are not predictable.

Pay closer attention to traffic patterns in and out of cities (e.g. don't leave for the Hamptons from New York City at 5pm on Friday), gasoline prices, and phenomena like the "driving season" between the last Monday in May (Memorial Day holiday) and the first Monday in September (Labor Day holiday) when traffic and fuel prices are higher.

  • Thank you. Looks like its going to be between 70 to 80 on the entire East coast this September. Weather is the main concern, since outdoor activities are topping our charts this vacation. Sep 5, 2013 at 16:44
