On a blazing sunny day, don't forget to put on sunscreen.
Tips
culture
《艳阳天》 is also the title of Hao Ran's 1964 novel, a canonical work of Mao-era rural literature — so the word carries a slight literary / nostalgic flavor for older readers.
usage
Stronger than 晴天: the 艳 ('gorgeous / vivid') adds intensity — a sunny day that's almost too bright. Often paired with summer or late spring.
