How to say "rainy" in Japanese?

Question:

As in..."It was a rainy season" or..."It was a rainy day today"

Thank you ^_^

Answer:

>As in..."It was a rainy season"
雨の季節 ame no kisetsu

"It was a rainy day
雨の日 ame no hi

>I've heard tsuyu refers to June-July, the Japanese rainy season.

Yes, you are right.

>would some sort of variation of "sore wa tuyu no jiki(kisetu) deshita." make sense if I was talking about the months of April & May?

No. Just use ame no kisetsu for other seasons. But I don't think April or May are rainy seasons in Japan.

Or you can use 雨季 uki for formal situation.
