Enjoy beautiful weather all year long on this 70 degree road trip through the interior of the United States…
In 2015, a clever climatologist routed a 70°F Road Trip map that steers you through 69-71°F all year long. Brian B.'s map has been shared over 10 million times over various platforms!
He updated the routes in 2023 to make them more interesting. You can now choose a Coastal Route, Interior Route, or an All U.S. and Canada Route.
You can see how he figured out these routes on Brian B.’s Climate Blog. We've already written about the Coastal Route, and in this article, we will focus on his interior route. Stay tuned for the third route next week!

Route 2: The Interior Expedition
At 7,064 miles, this route is only a few hundred miles shorter than the coastal route, but it takes you through the heart of America. It showcases an array of natural wonders, picturesque landscapes, and unique cultural experiences.
This incredible route starts in Brownsville, Texas, and weaves its way northwards along the country's interior. You ultimately make your way back down to the same final leg as the Coast Route through Phoenix to San Diego.
Keep in mind you don’t have to drive this entire route. It can serve as a guide to plan trips using segments at different times of the year. But if you have the time and resources, it sure would be an incredible journey to do the entire route!
We will walk you through this epic road trip and link to related articles to help you plan your trip.
