爽やか is a common everyday word for refreshing, fresh, or invigorating feelings, while 爽涼 is a more literary and elegant term specifically emphasizing coolness and refreshment.
涼しい is the standard adjective for cool temperature, whereas 爽涼 adds a nuance of crisp freshness and is used in more refined or written contexts.
Compound of 爽 (refreshing, invigorating) and 涼 (cool). The exact historical derivation is uncertain, but the combination naturally conveys a sense of cool freshness.
