The typically frigid Lake Superior has warmed up faster than usual this summer.

Researchers at the University of Minnesota Duluth say that's due to a winter with little ice and a record-warm spring.

They say surface water temperatures are already about 11 degrees Celsius higher than normal at one buoy in western Lake Superior. The researchers added that water temperatures could reach a record high by mid-August.

That's good news for people who want to swim in Superior's typically bone-chilling waters, but the long-term implications are so far unknown.

It could mean a more fertile lake with more organisms that thrive in warmer conditions, but lake trout may have to move deeper or further offshore.
