TOKYO—A solar plane attempting to fly around the world without a drop of fuel plans to make an unscheduled stop Monday night in Nagoya, Japan, because of bad weather.

Swiss pilot André Borschberg took off from Nanjing, China, on Sunday on what was to be the longest leg of the journey, a six-day, 8,175-kilometer (5,079-mile) flight to Hawaii.

Instead, the Solar Impulse 2 will land in Nagoya in central Japan, organizers said.
