Lately, there’s been plenty of talk about how windy it’s been in Duluth, and the data definitely supports it.

Let’s go back to 1955 and check the spring wind data in Duluth.

There’s definitely been an increase in the number of spring days with gusts of 30 mph or more in Duluth when you compare 2026 and 2025 to earlier years. Spring is often windy thanks to big temperature swings across the U.S., with strong low-pressure systems moving through. Whether something else is contributing to the winds is still up for debate.
Remember this spring, we’ve seen a huge temperature contrast, with well-below-zero temperatures lingering in parts of Canada into late March and even into April. Even now in mid-May, areas west and northwest of Hudson Bay, Canada, are still seeing temperatures in the teens and 20s, while the central and southern Plains are basking in 80- and 90-degree heat. This sharp contrast might be a big reason why it’s been such a windy spring in Duluth.
