A hot, humid night typical of tropical or subtropical regions, especially during summer.
지난 여름 내내 열대야 때문에 에어컨을 끄지 못했다.
All summer long I couldn't turn off the air conditioner because of the tropical nights.
Used to describe unusually warm nights; not a scientific term.
Think of ‘열대’ (tropical) + ‘야’ (night) to picture a night that feels like daytime.
Compound of 열대 (tropical) + 야 (night).
Commonly used in weather reports and everyday conversation to emphasize how hot the night feels.
