The heat just won’t stop.

Parts of the U.S. are set to experience unseasonably warm temperatures this week as parts of Europe are reeling from scorching September heat.

In the U.S., millions of Americans began feeling temperatures as much as 25 degrees Fahrenheit above October averages this week. Minneapolis hit a record high of 92 degrees Fahrenheit on Monday, far above its seasonal average of 66 degrees Fahrenheit, and organizers on Sunday canceled the city’s annual marathon due to record heat.

Meanwhile, Spain set a national heat record on Sunday as temperatures soared above 100 degrees Fahrenheit.

On the heels of the world’s hottest summer on record, September was also record-breaking across the globe: countries and cities from Austria to Moscow to Japan to New Zealand to Abilene, Texas all set records for their warmest Septembers.

“The El Niño won’t peak until later this year and there is plenty more heat waiting in the wings,” Michael McPhaden, a senior scientist at the National Oceanic and Atmospheric Administration, told the Washington Post. “So expect more records to be set in the coming months.”
