The best time to visit Singapore is generally during the dry season, which occurs from February to April. During these months, you can expect less rainfall and more sunshine, making it ideal for outdoor activities and exploring the city-state. Additionally, Singapore hosts several major events and festivals during this period, such as the Chinese New Year celebrations, the Singapore Arts Festival, and the World Gourmet Summit, adding to the vibrant atmosphere.

However, Singapore's tropical climate means it experiences relatively consistent temperatures and high humidity throughout the year. If you prefer to avoid crowds and don't mind occasional rain showers, you can also consider visiting during the shoulder seasons of December to January or May to July. These months still offer pleasant weather for sightseeing and activities, with fewer tourists compared to the peak season.
