Residents in the western end of Singapore are reporting incidences of hail.
Hail is a form of solid precipitation and consists of irregular lumps of ice.
Mr Lucas Ho, 28, playwright and teacher said: "The torrent came in a five-minute burst; something was clanging on my windows and I went to my front door to see what was going on. I never thought I'd see hail in Singapore."
There is no indication at the moment if the hail stones are related to the haze.
