Is the word chuvosos the same in Brazilian and European Portuguese?

Yes

The word "chuvosos" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference is pronunciation. In Brazil, the vowels are generally more open and the rhythm of speech is more "syllable-timed," meaning each syllable is given more distinct weight. In Portugal, the pronunciation is more "stress-timed," where unstressed vowels are often reduced or nearly swallowed, making the word sound more clipped and the unstressed syllables much shorter.

3. Tivemos meses muito chuvosos este ano. (We had very rainy months this year.)
