A pretty cool article for a year long road-trip while you stay in 70 F weather all the time.
Imagine that you really like days where the high temperature is 70°F and you wanted to plan a road trip where the temperature always hovers around 70°F. Well, I have done the planning for you. Since you cannot know what the temperature will be more than a week in advance (the current limit of decent forecasts), you have to go with Plan B; that is, look in a climate almanac. The go-to climate almanac for United States data is published by the National Center for Environmental Information (NCEI). The daily normal high temperature is computed for over 8,000 stations all across the United States. In addition, Environment Canada publishes monthly normals for stations across the great north. (Note: “normal” is a technical term that refers to a smoothed average for a 30-year period. It is close to an arithmetic average but not exactly the same.)
