MPCA forecasts up to 16 smoky days this summer

The Minnesota Pollution Control Agency anticipates between 12 and 16 days affected by wildfire smoke this summer, conditions similar to those experienced in the summer of 2024.

A strong El Niño-southern oscillation cycle is expected to create conditions for a drier and warmer summer, punctuated by storms. Some parts of the state could experience below-average rainfall and drought conditions.

The MPCA issued a reminder to Minnesotans that smoke from wildfires can contain fine particles that pose health risks, even for healthy individuals.

“Minnesotans rely on timely, accurate, science-based forecasts to plan their days and protect their health,” said MPCA Meteorologist Matt Taraldsen. “We want to give people the information they need to make smart choices — whether it’s rescheduling a run, protecting a child with asthma, or delaying the backyard chores. This summer, conditions are lining up for several air quality alert days, so staying ‘air-aware’ is more important than ever.”

Last May, the Camp House Fire burned nearly 12,000 acres in St. Louis County. This weekend, the National Weather Service issued a Red Flag Warning for 26 counties in parts of central and northwest Minnesota because of extreme fire risk.

Air quality can be affected by wildfires outside of Minnesota. Last summer, wildfires in Canada created unhealthy air quality across Northern Minnesota.

Minnesotans can sign up for air quality alerts and check daily forecasts at the MPCA AQI forecast webpage for a daily discussion of statewide conditions. Updates and alerts are also posted on Facebook and X.
