play on words

[mushou]

Hello! Can somebody tell me if a word "夏日和" have a meaning?
In dictionary I only find "春日和" 【はるびより】 which means "Indian summer". So I wonder if 夏日和 have any sens or it's some play on words?
I am curious to find the meaning of this word 夏日和 and it would be great if somebody help me with this
