The climate in Singapore, just north of the equator, remains fairly constant at 85 degrees with high humidity and a chance of showers. 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 throughout any given day. It takes 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.
