The three warmest cities in Colorado are La Junta, Lamar, and Grand Junction.
In this article I’m going to share with you my ranking of the warmest places in Colorado.
I created my list by researching data provided by the National Oceanic and Atmospheric Administration and other climate data providers.
Below I’m listing the top 10 warmest places in Colorado that have the highest average yearly temperatures. Later in the article I share a table with 50 most populous cities in Colorado.
Top 10 Warmest Cities in Colorado
Here are the top 10 warmest cities in Colorado ranked by their daily mean temperature. While the differences between the top 10 may not be that huge, the differences between these warmest cities and the average for the researched 50 municipalities (47.77 °F) is much more noticeable.
1. La Junta – daily mean temperature of 54.25 °F
Located on the Arkansas River, La Junta is the warmest city in Colorado. It’s warmer than Denver by 3.1 °F and Colorado Springs by 3.8 °F. If you’re looking for the warmest place in Colorado with the highest daily mean temperature, this small city of a little over 7,000 inhabitants is your best option. Note that the reason why La Junta is first is because in addition to having milder winters it has hotter summers than other destinations in Colorado. If you’d rather avoid hotter summers, read on for other options.
2. Lamar – daily mean temperature of 53.5 °F
Another small city, called Lamar, takes the second spot in the ranking. It’s slightly cooler than La Junta but the difference is barely noticeable. If you’re looking for a small city in Colorado with warm weather, both options will work well. Lamar is further away from the Rocky Mountains, though.
3. Grand Junction – daily mean temperature of 53.2 °F
Grand Junction, with over 65,000 inhabitants, is the most populous city in western Colorado. It’s one of the largest and warmest cities in the state. It enjoys plenty of sunny days year round and has a dry, cold semi-arid climate. December and January average highs in the city are much lower than in the previous two towns (about 38 °F in Grand Junction compared to 45 °F in La Junta and Lamar).
4. Northglenn – daily mean temperature of 52.4 °F
Northglenn is a city of 35,000 residents located in the Denver–Aurora–Lakewood metropolitan area. Northglenn has some of the mildest winters in this ranking. Average highs in the coldest month reach 48 °F, with nighttime temperatures dropping to 19 °F. This is warmer than about 45 °F in Denver and Colorado Springs.
5. Fruita – daily mean temperature of 52.25 °F
Known for its outdoor recreational opportunities like mountain biking and white-water rafting, Fruita is the fifth warmest city on this list. Like Grand Junction (because it’s a part of its metropolitan area), Fruita has colder winters than other warmest places featured in this list. It also has little precipitation in this already dry state.
6. Greeley – daily mean temperature of 52.05 °F
Greeley is a city of over 100,000 inhabitants, conveniently located about an hour drive north of Denver and 40 minutes away from Fort Collins. It’s also about an hour and a half drive from the Rocky Mountain National Park. It’s the second most populous city featured in this ranking. If you’re looking for a bigger warm city in North Colorado, Greeley is a good option to consider.
7. Cañon City – daily mean temperature of 52.05 °F
Cañon City, located close to the renowned Royal Gorge Park, is often described as the warmest place in Colorado, enjoying the best weather in the state. Based on my research, it does have by far the mildest winters, with temperatures reaching almost 50 °F during the day (and 18 °F at night) in the coldest month. The reason why Cañon City isn’t first in this ranking is that its annual daily mean temperature is lower than for other cities due to having a lower average summer temperature. Of course, if you don’t want the hottest temperature in the summer, Cañon City is going to be a better choice than cities having colder winters but hotter summers.
8. Trinidad – daily mean temperature of 52.05 °F
Trinidad is a small town of a little over 8,000 inhabitants. It’s located on the Purgatoire River in southern Colorado, close to the border with New Mexico. It has the second mildest winters in the state after Cañon City, enjoying average daily highs of 48 °F and 19 °F average lows in January. It also has slightly cooler summers than Cañon City.
9. Pueblo – daily mean temperature of 52 °F
Pueblo is located about an hour drive north of Trinidad and about 40 minutes south of Colorado Springs. With over 110,000 residents, it’s the most populous city in this ranking. Like Trinidad, it has some of the warmest winters in the state. The main difference between Pueblo and Trinidad is that Trinidad has slightly warmer winters and slightly cooler summers than Pueblo.
10. Commerce City – daily mean temperature of 51.53 °F
Commerce City is the second city in this ranking that’s located in the Denver–Aurora–Lakewood metropolitan area. The difference between Commerce City, the tenth warmest place in the state, compared to La Junta, the warmest place in the state, is 2.72 °F. Commerce City is a bit cooler year round, both in the winter and in the summer.
50 Biggest Cities in Colorado Ranked by Daily Mean Temperature
I created the table below by researching data for the 50 most populous municipalities in Colorado. When I couldn’t find data for a given municipality, I moved on to another. While the list includes 50 cities, some of the bigger cities may be missing because there was no data for them. Please check the closest geographically city then.
