Perched just north of the equator, Singapore’s weather is a fairly constant 85 degrees with high humidity and a chance of showers year-round. It rains slightly more than average between November and January, and slightly less from May to July. Rain clouds tend to swoop in quickly, unleash a torrent, and then clear out again, so it’s quite common to switch between sunglasses and an umbrella multiple times a day. It takes some time to adjust to the high humidity, so walk at a leisurely pace and drink plenty of water. The temperature doesn’t change much when the sun goes down, but you may need a light sweater or shawl to insulate yourself against the Singaporean tendency to over-air-condition indoor spaces.
