A clever climatologist routed a 70 degree road trip around the U.S., where you can enjoy 70-degree weather all year long…
In 2015, a climatologist named Brian B. created a 70°F Road Trip map that has been shared over 10 million times over various platforms. The map consists of 3 different routes that chase 70-degree weather all year long.
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 Brian B.’s Climate Blog and how he figured these routes out. In this article, we will focus on what Brian B. calls the Coastal Route. We'll cover the other two routes in upcoming articles.
Keep in mind you don't have to do this entire route. You can simply use it as a guide to plan trips using segments at different times of year. But, if you have the time and resources, it sure would be an epic journey to do the entire route!

Route 1: The Coastal Adventure
The coastal route of Brian B.'s 70 degree road trip starts in Tampa, Florida and ends in San Diego, California. It's an extraordinary 7,468-mile journey through diverse landscapes and coastal views.
Brian calls it the coastal route because it takes you along the east coast and follows the shores of some of the great lakes, and finishes off on the southern coast of sunny California. However, this route may be better designated the “exterior” or “perimeter” route…
It has a long stretch across the northern states and a detour inland once you get out west. That's what is required to stay within the 69-71 degree window.
But, even though it doesn't take you entirely down the Oregon and California coastline, you'll still see amazing landscapes every mile of the journey.
We're going to walk you through the journey and link to helpful articles to help you plan your trip.
Set off from Tampa, Florida, and make your way east toward Orlando. Enjoy the warm weather, sandy beaches, and vibrant attractions, including theme parks, shopping, and dining experiences.
