"今日は天気がいいですね。"

Translation: The weather is good today, isn't it?

[cyborgk9]

For the Canadians, can you support "eh?" instead of "isn't it?"...? ;)

[RobertKols]

Why do we use いい here and not よく？

[Fayke]

よく is an adverb, the corresponding adjective is よい or いい (it is handy to remember that いい is originally よい when you conjugate it).

[andi_kan]

Excuse me, would you please elaborate "remember that いい is originally よい when you conjugate it". I don't follow. Thanks ^_^

[DramaJay]

よい is the original word for "good", but it turned into いい

[HelpfulDuo]

「今日は天気がよいですね。」is the original sentence, which is used for writings and formal situations. In conversation you'll hear 「いいですね」 a lot more often. 「よいです。」is the opposite of 「わるいです。」

[iOfg2]

いい is an irregular adjective

いい - it is good
いかった - it was good
よくない - it is not good
よくなかった - it wasn't good

[V2Blast]

*よかった, not いかった

[thomasleft]

いかった is a dialect of Hokkaido, so it's not entirely wrong.

[BenWright18]

should accept "isn't the weather good today?"

[Kaza624]

I hear na instead of ga in 天気が
Why?

[GALAXIILUNA]

i heard that too

[mocky55]

"Weather today is good isn't it?"
Pretty depressing that isn't allowed either

[James151779]

Since there tense can either be present (as in Duo's answer) or future, would not "the weather will be good today, won't it" be correct? Am I missing something?

[phival1]

"Today's weather is fine, isn't it?" doesn't pass either... Huuuuuumm

[LunetitaSe]

天気がいいから さんぽしましょう. XD
