November to January and June to July are the best time to visit Singapore. However, season-wise Singapore remains more or less pleasant all year round.
November to January constitute the peak season in Singapore. Although the weather in this island country is pleasant throughout the year, these months see a high tourist footfall owing to the Christmas and New Year when this tourism hotspot sees the highest number of revellers and party-goers.
June to July is the shoulder season in Singapore as it sees Singapore host the shopping festival, which is a favorite among the shopping lovers. In addition to this, Singapore also hosts the Great Singapore Food Festival around the same time. The weather is hot and humid all year round, however, April sees the least likelihood of unexpected showers and is an ideal time to visit.
August to October is the off season to visit Singapore. However, mid-September sees a rush of motorsport fans as Singapore gets ready to host the Grand-Prix. The weather remains hot and humid with occasional heavy showers. However, it is a good time to get bargains on hotels and transport rates.
