What Are the Warmest Cities in Wisconsin?

KEY TAKEAWAYS
The three warmest cities in Wisconsin are Milwaukee, West Allis, and La Crosse.

In this article I’m going to share with you my ranking of the warmest places in Wisconsin.

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 Wisconsin that have the highest average yearly temperatures. Later in the article I share a table with 50 most populous cities in Wisconsin.

Top 10 Warmest Cities in Wisconsin

Here are the top 10 warmest places in Wisconsin ranked by their daily mean temperature.

1. Milwaukee – daily mean temperature of 49.3 °F

The warmest city in Wisconsin is its largest city, Milwaukee. According to weather data, the average weather you can expect in Milwaukee is 31-36 °F during a winter day and 17-23 °F during a winter night. Average summer maximum temperature is 77-82 °F, dropping to 58-65 °F at night. Out of all Wisconsin cities featured in this ranking, Milwaukee gets most days with snow, at 35 days a year, between November and April. Still, it’s the hottest city in the state. And at 2,483 sunshine hours a year, the city gets enough sunny days that there are only three months when sun shines less than 50% of the time.

2. West Allis – daily mean temperature of 49.1 °F

West Allis is a suburb city of Milwaukee. Because it’s nearby, both cities have a similar daily mean temperature. West Allis is further inland, though. That gives it colder winter nights, with the average temperature up to 3 degrees lower. West Allis also experiences warmer summer days (by up to 3 degrees, too).

3. La Crosse – daily mean temperature of 48.85 °F

La Crosse, a city on the Mississippi River on the border with Minnesota, has a more extreme climate than the first two cities. In the winter, it’s noticeably colder. Average highs reach 27-33 °F compared to 31-36 °F in the previous two cities. Nights in particular are much colder, with temperatures up to 7 degrees lower than in Milwaukee. The reason why La Crosse still ranks third is because the warmest months in this city are much warmer than in the previous two. During an average summer, the high temperatures reach 82-85 °F and nights don’t drop below 60 °F.

4. Janesville – daily mean temperature of 48.7 °F

Janesville, located in Southern Wisconsin, 77 miles southwest of Milwaukee, shares a climate similar to La Crosse. It also has colder nights and warmer summers, though they aren’t as warm as in the latter. Compared to other Wisconsin cities, it still has some of the warmest summer months.

5. Kenosha – daily mean temperature of 48.4 °F

Kenosha is the fourth largest city in Wisconsin. Located on Lake Michigan, 35 miles south of Milwaukee, it has a very similar climate. The main difference between these two cities is that Kenosha gets 20 days of snow instead of 35 days of snow in Milwaukee. If you’re looking for the best weather in Wisconsin and you don’t like snow, Kenosha may be a better option than Milwaukee even though it’s slightly colder.

6. South Milwaukee – daily mean temperature of 48.4 °F

South Milwaukee is situated 10 miles south of downtown Milwaukee. As West Allis, it’s a part of the metropolitan area. The city gets summers with temperatures up to 2 degrees cooler than in Milwaukee.

7. Wauwatosa – daily mean temperature of 48.25 °F

Wauwatosa is located immediately west of Milwaukee. The city offers a less attractive climate, with slightly colder winters and slightly warmer summers. It has fewer days of snowfall, though, due to being further inland.

8. Delavan – daily mean temperature of 47.6 °F

Delavan is located in Southern Milwaukee, on the Delavan Lake. This town of about 8,000 inhabitants has winters with temperatures between 29-35 °F during the day and 13-20 °F at night. Summers reach average temperatures between 79-83 °F during the day and 57-61 °F at night (which is up to 4 degrees cooler than in Milwaukee).

9. Sheboygan – daily mean temperature of 47.55 °F

Sheboygan is a city of 50,000 located 58 miles north of Milwaukee. Like Milwaukee, it’s located on Lake Michigan which gives it a more moderate climate. It’s cooler than the largest city in Wisconsin, though, with temperatures lower by 1-2 degrees.

10. Monroe – daily mean temperature of 47.25 °F

Monroe is the tenth warmest city in Wisconsin. Due to its southerly location close to the border with Illinois, it has a similar climate to Janesville. Despite being ranked tenth, this city of about 11,000 people is still much warmer than cities in other parts of Wisconsin that have an average annual temperature up to a few degrees lower. It’s one of the warmest small cities in the state.

50 Biggest Cities in Wisconsin Ranked by Daily Mean Temperature

I created the table below by researching data for the most populous municipalities in Wisconsin. When I couldn’t find National Oceanic and Atmospheric Administration data for a given city, 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.
