That might be the correct work order in Arabic but, in English, it would be "a hot and rainy summer."
or, indeed, "a hot rainy summer". Which is OK English, but they weren't having it. "A rainy and hot summer" is just plain wrong.
1:Summer is rainy and hot.
2:A rainy and hot summer.
3:A hot and rainy summer
But duo ?
Def they are talking about indonesia
we would really say: "a hot (and) rainy summer". Too many wrong corrections!!
