Best time to visit Singapore
Aim for January to June if you get the choice: humidity and rainfall are at their lowest, which is what actually varies here, and highs average 85°F (29°C) against roughly 24 wet days a month. For the same question asked the other way round, see where else is warm in January.
Pack for Singapore with light clothing for the warm months, proper waterproofs rather than an umbrella - wet days are the norm here and moisture-wicking fabrics for the humidity. May nights average 79°F (26°C), so evenings rarely match the afternoons.
