"天气很好，我们去爬山吧！"

Translation: The weather is good, let's go hiking!

[hq4]

Let's go mountain climbing!

[FuCnSW]

No, it's different word. Mountain climbing is 登山. Hiking means 爬山 or 健行.

[KX3.]

Yes, this is more accurate.

[johnsark]

I agree!

[BrendanKav1]

Me too

[Yojohnny]

The weather is great. Let's go hiking!

"The weather is fine. Let's go hiking" would also be a correct translation. Reported on Nov. 19, 2017.

good = hen hao,
fine = hai xing

[KX3.]

Fine would be something like 不错

I believe 登山 is also a widely accepted translation for hiking. Whereas 爬山 connotes non-technical mountain climbing activities and 攀岩 would refer to technical rock climbing with ropes and harnesses and gear, etc. No? I think "Let's go mountain climbing should be accepted."

[KX3.]

Hiking includes non-technical mountain climbing activities and 登山 is usually only for mountain climbing, actually.

[Yojohnny]

The weather is fantastic. Let's go hiking!

[BZH1423]

I think they would use a stronger modifier (i.e. 非常) if they wanted to say "fantastic" over simply "good."

[KX3.]

Yes, that's right.

[MatthewWon99]

I used "weather with aposthrophe s" instead of "weather is" and i got it wrong...

[TaffytheLogolept]

I said "so good" and got rejected. :(
