is the weather always nice in Hawaii and neighboring islands or is it too humid .?

i always picture tropical islands as being beautiful but a friend of mine said that there warm year round but not at all comfortable, he said it is always humid and sticky and there are tons of bugs that never leave you alone and that it is the most miserable place he had ever been. is this true? im not even sure he really ever went to Hawaii so i dont know what to beleive.
