今年の夏が例年になく暑かったせいなのかは分かりませんが、奇妙な発疹が胸に出ましてね。
I’m not sure if it was because this summer was unusually hot, but a strange rash broke out on my chest.
That's very odd and strange, making it odd and strange.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
