晴朗 (qíng lǎng) is an adjective describing weather that is clear and bright—typically with a cloudless blue sky, abundant sunlight, and good visibility. The first character 晴 means 'clear (of the sky)' and specifically refers to absence of rain or clouds; the second character 朗 means 'bright', 'lucid', or 'cheerful', reinforcing the sense of luminosity and openness. Together, they form a compound that emphasizes both visual clarity and radiant light—not merely 'not raining', but positively sunny and refreshing.

This word is commonly used in daily conversation, weather reports, travel descriptions, and literary writing to evoke pleasant outdoor conditions. It often appears in fixed phrases like 晴朗的天气 (qínglǎng de tiānqì, 'clear weather') or 晴朗的一天 (qínglǎng de yī tiān, 'a clear day'). While it can occasionally describe mood metaphorically (e.g., 晴朗的心情), its primary and most frequent use remains meteorological.
