Singapore Climate and Weather
Singapore enjoys a tropical climate, which means it's warm and humid year-round, with little variation in temperature. Travellers should expect sunshine, sudden downpours, and lush greenery no matter when they visit. The wettest months are typically from November to January, and the western part of the island tends to receive more rain than the east.
Daytime temperatures hover between 74°F (23°C) and 89°F (32°C), dipping slightly at night. April and May are usually the hottest months, while humidity stays consistently high, and is often above 75 percent. Thankfully, air-conditioning in most buildings offers a cool escape, though it can be chilly indoors; packing a light sweater isn't a bad idea.
From June to September, occasional haze from forest fires in Indonesia may affect air quality. While there's no definitive 'best' time to visit, many find the weather most pleasant between June and August.
