We has been there twice. The first time it rained, so we went back there on another evening and we were luckier becuase it was cloudy, breezy but without rain. (July is the month that the rain season started) However, it's recommended to visit the riverfront on the evening and at night to see a more stunning atmosphere and to avoid hot weather.
These are some of our pictures.
I'll be back soon with more pictures from the ferris wheel! ;)
